✈️ One team trip per year to a destination that doesn't suck
About the role:
We are building ULTIMS, the e-commerce platform we always wished existed. Not a Shopify clone. A serious, API-first, multi-storefront commerce system with native marketing automation, AI-powered services, and the most reliable server-side event tracking in the industry. We're building it first for ourselves (TOSSIT, a fast-growing consumer brand operating across 10+ markets), then opening it to others.
The data model and event tracking architecture are already in progress with our co-founder. You are not inheriting someone else's finished decisions, you are walking into the most critical moment: validating the foundation and making the calls that will define everything built on top of it. That's not a warning. That's why this role is interesting.
Key responsibilities:
1. Technical leadership:
- Validate and finalize the system architecture alongside the co-founder before a single line of production code is written
- Define coding standards, API structure, service boundaries, and development processes for the entire team
- Lead and mentor a team of 5 engineers across backend, frontend, DevOps, and AI
- Review code, enforce quality standards, and make the hard calls when tradeoffs need to be made
- Implement CI/CD pipelines, automated testing strategy, and deployment processes
- Run standups, sprint planning, and technical retrospectives
2. System design & implementation:
- Design a multi-storefront e-commerce system where one Go backend serves multiple market-specific React frontends
- Architect the native marketing automation layer, product-aware, event-driven, deeply integrated
- Build a robust internal and external API framework
- Ensure the system is built to last 5+ years without a rewrite
3. Performance & reliability:
- Design for low latency and high throughput from day one, this will handle real transaction volume
- Implement caching, database indexing, and load balancing strategies
- Ensure maximum availability across all storefronts and markets
4. Security & compliance:
- Implement security measures across all aspects of the platform.
- Monitor and address vulnerabilities promptly.
- Ensure compliance with data protection and privacy regulations.

- Solid experience with Kafka, Kubernetes, and cloud-native infrastructure
- Expertise in building and scaling APIs under real traffic
- Familiarity with server-side event tracking architecture (Meta CAPI, GA4, etc.) is a strong plus
- CI/CD fluency and automated testing discipline
2. Leadership & mindset:
- Experience in Agile methodologies, you run the process, not the other way around
- You break down complex problems and delegate without losing quality
- Strong opinions, clearly communicated, we are not looking for someone who just executes
- You will work directly with a technical co-founder who has strong convictions; you need to be able to challenge them constructively and be challenged in return
3. Soft skills:
- High attention to detail, proactive mindset, and genuine adaptability
- Strong problem-solving ability and architectural creativity
4. Language proficiency:
- Excellent English. All communication, documentation, and code reviews are in English. You will be the technical voice of this project with founders and the team alike. Near-native fluency is a genuine requirement, not a formality.
Who we are looking for:
A technical leader who has shipped serious products and knows what "built to last" actually means in practice. Someone who thrives when the foundation isn't fully laid yet, because laying it correctly is the job. You don't wait for perfect specs. You ask the right questions, make defensible decisions, and move the team forward. You want to own something from the ground up and watch it scale.

- Comfortable with Docker, Kubernetes, and CI/CD pipelines
- You understand the difference between building for one market and building for ten
2. Problem-solving skills:
- Proven ability to diagnose and resolve complex backend issues under pressure
- Experience optimizing systems for performance and scalability at real traffic levels
- You ask questions early rather than building the wrong thing for two weeks
3. Soft skills:
- Attention to detail without losing sight of the bigger picture
- You communicate clearly in writing, because that is how this team operates
- Adaptable, you will be working on a system that evolves fast
4. Language proficiency:
- Strong written English. All documentation, code reviews, and async communication are in English. You don't need to be a native speaker, but your written clarity needs to be sharp. Technical precision in writing matters as much as in code.
Who we are looking for:
A backend engineer who takes ownership of what they ship. You have built serious systems before, you know what clean architecture looks like, and you are not afraid to push back when a technical decision is wrong. You thrive in early-stage environments where the scope is ambitious and the team is lean. You want to build something that lasts.

- Work closely with the Data and Tracking Engineer on event schema design and pipeline reliability
- Ensure tracking infrastructure is resilient to front-end failures, ad blockers, and browser-level restrictions
4. Kafka and data pipeline infrastructure:
- Manage and scale Kafka infrastructure for real-time event streaming across the platform
- Ensure data pipeline reliability and monitor for lag, failure, and data loss
- Build observability into every layer of the data infrastructure
5. Monitoring and reliability:
- Implement a full observability stack: metrics, logs, and traces using Grafana, Prometheus, or equivalent
- Define SLOs and build alerting that actually matters, no alert fatigue
- Ensure the team knows about problems before users do
- Own incident response processes and post-mortems
6. Security and compliance:
- Implement network security, secrets management, and access control across all infrastructure
- Ensure GDPR compliance at the infrastructure level, data residency, encryption at rest and in transit
- Conduct regular security audits and vulnerability assessments
Stack:
Kubernetes · Docker · CircleCI · Kafka · Terraform · AWS or GCP · Grafana · Prometheus · Git
Server-side tracking: Meta CAPI · Google Ads API · GA4 Measurement Protocol · TikTok Events API
Requirements:
1. Technical:
- Proven experience running production infrastructure for transactional systems, e-commerce experience is a strong plus
- Strong Kubernetes and Docker expertise in real production environments

- You document what you build so the team is not dependent on you alone
- You push back when architectural decisions will create operational nightmares
3. Soft skills:
- Clear written communicator in a distributed async team
- You escalate early when something is at risk, you do not wait until it is broken
- Detail-oriented but pragmatic, you know when perfect is the enemy of shipped
4. Language:
Working English. All documentation, runbooks, and code reviews are in English. Day-to-day collaboration can be supported locally. Written technical clarity is what matters here.
Who we are looking for:
A DevOps engineer who has run real infrastructure under real pressure and knows what breaks when traffic spikes. You understand that in e-commerce, downtime and tracking failures are directly measurable in lost revenue. You want to build the infrastructure layer of something ambitious from the ground up, own it completely, and make it something you are proud of.
AI / Automation Engineer

Work structure:
📅 Workweek: 40 hours
🏖️ Paid days off: 30 days per year (including public holidays)
🌏 100% remote, work from anywhere
⌚ Flexible working hours
💸 Salary: €4,000/month
💰 Performance bonus: Up to €4,500 annually based on individual performance and project delivery
✈️ One team trip per year to a destination that doesn't suck.
About the role:
ULTIMS is a next-generation e-commerce platform built API-first, designed to serve multiple storefronts across multiple markets from one robust backend. We are building it for ourselves first (TOSSIT, a fast-growing consumer brand operating across 10+ markets), then opening it to others.
As AI and Automation Engineer, you are building the intelligence layer of the platform. Not AI as a buzzword. AI as a genuine operational advantage: workflows that remove hours of manual work, translation pipelines that actually work at scale, automation that connects product data, pricing, inventory, and marketing into one coherent system. You will integrate with Anthropic's API as the primary AI backbone and build the orchestration logic that turns AI outputs into real, accountable business actions.
This is not a research role. Everything you build ships to production and handles real volume.
What you'll own:
1. Translation and content automation:
- Build the translation pipeline that is the first major AI service inside ULTIMS
- AI generates translations across all market languages, a human reviews and approves or overrides
- Design the approval workflow so it is fast, auditable, and genuinely useful to non-technical operators
- Ensure translation quality is measurable and improves over time through feedback loops
- Connect translations directly to the product catalog, pricing, and storefront content layers
2. Workflow orchestration:
- Design and build the workflow engine that powers automated processes across the platform
- Implement orchestration using Temporal or equivalent to manage long-running, stateful workflows
- Ensure workflows are observable, recoverable, and explainable to non-technical stakeholders
- Build the human-in-the-loop approval mechanisms that keep AI actions accountable
3. Anthropic API integration:
- Own the integration with Anthropic's API as the primary LLM backbone of the platform
- Design prompt architecture that produces consistent, reliable, production-safe outputs
- Implement output validation, failure handling, and fallback logic so AI failures degrade gracefully
- Stay current with Anthropic's model releases and evaluate when and how to adopt new capabilities
4. AI services expansion:
- After the translation pipeline, identify and prioritize the next highest-value automation opportunities inside the platform
- Candidates include: automated product description generation, dynamic pricing suggestions, marketing workflow triggers, customer segmentation logic
- Work closely with the product team and founders to evaluate what gets built next based on real operational pain
5. Integration with platform services:
- Connect AI services deeply with the backend: product catalog, inventory, order data, pricing, and the marketing automation layer
- Ensure AI services consume and produce clean, structured data that the rest of the platform can rely on
- Build APIs that expose AI capabilities to other services cleanly and safely
Stack:
Python or Go · Anthropic API · Temporal or equivalent workflow orchestration · REST APIs · Kafka · Docker · Git
Nice to have: experience with other LLM APIs, familiarity with e-commerce workflows, experience building human-in-the-loop systems
Requirements:
1. Technical:
- You have shipped AI-powered features in production, demos and prototypes do not count
- Solid experience integrating with LLM APIs, prompt engineering, and managing the unpredictability of AI outputs in production systems
- Experience with workflow orchestration tools, Temporal, n8n, Airflow, or equivalent
- Comfortable building in Python or Go, the team works in both
- You understand the difference between an AI feature that works in a notebook and one that works reliably at scale
- Experience building human-in-the-loop systems where AI acts and humans validate is a strong plus
2. Mindset:
- You are pragmatic about AI, you know when it is the right tool and when it is not
- You design for failure because LLMs fail in unpredictable ways and your systems need to handle that gracefully
- You think about the operator experience, not just the technical implementation
- You measure the impact of what you build, AI features that cannot be evaluated are not finished
3. Soft skills:
- You communicate clearly with non-technical stakeholders about what AI can and cannot do
- You document your prompt architecture and workflow logic so the team is not dependent on you alone
- Curious and fast-moving, this space evolves weekly and you keep up with it seriously
4. Language:
Strong written English. Documentation, code reviews, and async communication are in English. You'll work across the stack with multiple team members, so written precision is important. Conversational fluency is a plus.
Who we are looking for:
An engineer who has moved past the excitement of AI and into the harder work of making it reliable, useful, and production-ready. You have built things with LLMs that real users depend on, and you know where the sharp edges are. You want to build the AI layer of a serious commerce platform from scratch, own it completely, and expand it as the product grows. You are not waiting for someone to hand you a spec. You identify the highest-value problems and go solve them.
Data & Tracking Engineer
📍 Location: Fully remote, worldwide. Occasional team meetups.
Work structure:
📅 Workweek: 40 hours
🏖️ Paid days off: 30 days per year (including public holidays)
🌏 100% remote, work from anywhere
⌚ Flexible working hours
💸 Salary: €4,000/month
💰 Performance bonus: Up to €4,500 annually based on individual performance and project delivery
✈️ One team trip per year to a destination that doesn't suck.
About the role:
ULTIMS is a next-generation e-commerce platform built API-first, designed to serve multiple storefronts across multiple markets from one robust backend. We are building it for ourselves first (TOSSIT, a fast-growing consumer brand operating across 10+ markets), then opening it to others.
As Data and Tracking Engineer, you are building one of the most critical and most underbuilt layers in e-commerce: an event tracking system that actually works. Not GTM tags that fire half the time. Not browser-dependent pixels that ad blockers kill. A proper server-side tracking infrastructure that captures every meaningful event accurately, in real time, and feeds it to every platform that needs it. This is the core reason ULTIMS exists. You own it.
You sit at the intersection of engineering and marketing performance. You need to understand both sides deeply enough to build something that engineers trust and marketers can actually use to make decisions.
What you'll own:
1. Server-side event tracking architecture:
- Design and implement the complete server-side tracking infrastructure from scratch
- Build the event pipeline that feeds Meta CAPI, Google Ads API, TikTok Events API, GA4 Measurement Protocol, and any additional platform as needed
- Ensure every purchase, add-to-cart, checkout initiation, and custom conversion event is captured accurately and in real time regardless of browser behavior, ad blockers, or client-side failures
- Define the event schema and naming conventions that the entire platform will use consistently
- Work closely with the DevOps engineer on infrastructure reliability and the Frontend Engineer on client-side data layer implementation
2. Attribution and data quality:
- Design an attribution model that goes beyond last-click and gives the marketing team a genuine picture of what is driving revenue
- Implement deduplication logic so the same event is never counted twice across server-side and client-side sources
- Build data quality monitoring so tracking failures are detected immediately, not discovered weeks later when the numbers look wrong
- Ensure event data is clean, consistent, and trustworthy enough to make real budget decisions on
3. Marketing data layer:
- Define and maintain the full data layer architecture across all storefronts
- Ensure product data, pricing, inventory status, and customer signals are available to the tracking layer in the right format at the right time
- Build the connection between the Kafka event stream and the external tracking platforms
- Work with the AI and Automation Engineer to ensure marketing automation workflows are fed accurate, real-time behavioral data
4. Analytics and reporting infrastructure:
- Build the internal analytics infrastructure that gives the TOSSIT marketing and performance teams visibility into what is happening across all markets
- Ensure data flows cleanly from storefront events through to reporting dashboards
- Work with the product team to define what metrics actually matter and make sure they are measurable
5. Compliance and data governance:
- Ensure all tracking implementation is GDPR compliant, consent-aware, and respects user privacy preferences across all markets
- Implement data retention policies and anonymization where required
- Document the full tracking architecture so any team member can understand what is being collected and why
Stack:
Server-side tracking: Meta CAPI · Google Ads API · GA4 Measurement Protocol · TikTok Events API
Data infrastructure: Kafka · MongoDB · SQL · Python or Go · Docker · Git
Analytics: Grafana or equivalent · custom dashboarding
Nice to have: experience with attribution modeling, CDP platforms, or previous work on high-volume e-commerce tracking
Requirements:
1. Technical:
- You have built server-side tracking systems in production, installing GTM tags is not this job
- Hands-on experience with Meta CAPI and at least two other server-side tracking APIs
- Solid understanding of event-driven architecture and how to design reliable event schemas
- Comfortable with Kafka or equivalent for event streaming
- Proficient in Python or Go for building tracking services and data pipelines
- You understand deduplication, event matching, and why these matter for ad platform performance
- Experience with data quality monitoring and alerting
2. Analytical mindset:
- You understand attribution well enough to explain its limitations honestly to a marketing team
- You know the difference between data that looks right and data that is right
- You can translate between engineering concepts and marketing performance language without losing either audience
- You make decisions based on data quality, not just data volume
3. Soft skills:
- Clear communicator with both technical and non-technical stakeholders
- You document everything because tracking systems that only one person understands are a liability
- Detail-oriented to a degree that most engineers find excessive, in this role that is a requirement not a quirk
- You escalate data quality issues immediately, you do not wait to see if they resolve themselves
4. Language:
- Strong English. You'll work with both engineers and marketers, and the ability to communicate clearly across both worlds is part of the job. Documentation, specs, and async communication are all in English. This role requires you to translate technical complexity into plain language regularly.
Who we are looking for:
An engineer who has felt the pain of bad tracking firsthand and decided to fix it properly. You have built server-side event pipelines that marketing teams actually trust, and you understand why that trust is so hard to earn and so easy to lose. You care about data quality the way a backend engineer cares about uptime. You want to build the tracking foundation of a serious commerce platform from scratch and make it the most reliable part of the system.
Technical Product Manager
📍 Location: Fully remote, worldwide. Occasional team meetups.
Work structure:
📅 Workweek: 40 hours
🏖️ Paid days off: 30 days per year (including public holidays)
🌏 100% remote, work from anywhere
⌚ Flexible working hours
💸 Salary: €3,500/month
💰 Performance bonus: Up to €4,000 annually based on individual performance and project delivery
✈️ One team trip per year to a destination that doesn't suck.
About the role:
ULTIMS is a next-generation e-commerce platform built API-first, designed to serve multiple storefronts across multiple markets from one robust backend. We are building it for ourselves first (TOSSIT, a fast-growing consumer brand operating across 10+ markets), then opening it to others.
As Technical Product Manager, you are the person who makes the team build the right things in the right order. You sit between ambitious founders with a large vision and a team of engineers who need clear, actionable specs to execute against. Without you, the team builds fast in the wrong direction. With you, every sprint moves the product measurably forward.
This is not a coordination role. This is not someone who schedules standups and updates Jira tickets. You need to understand the technical architecture deeply enough to write specs engineers do not have to rewrite, understand the business well enough to make hard prioritization calls, and have the spine to push back on scope creep from founders, from the team, and from yourself.
What you'll own:
1. Roadmap and prioritization:
- Own the product roadmap and ensure it reflects genuine business priorities, not just the loudest voice in the room
- Make hard calls about what gets built now, what gets built later, and what does not get built at all
- Balance the short-term operational needs of TOSSIT against the long-term platform ambitions of ULTIMS
- Revisit and update priorities based on what the team learns in production, not just what was decided six months ago
2. Specification and requirements:
- Translate founder vision and business requirements into technical specs that engineers can build from without ambiguity
- Write user stories, acceptance criteria, and edge case documentation that covers what happens when things go wrong, not just when they go right
- Work directly with the Lead Dev to validate that specs are technically feasible before they enter a sprint
- Maintain a backlog that is always groomed, always prioritized, and never a graveyard of half-baked ideas
3. Sprint management and delivery:
- Run sprint planning, standups, and retrospectives with discipline but without bureaucracy
- Track delivery against commitments and flag risks early, not after the deadline has passed
- Remove blockers fast, whether that means making a decision, escalating to founders, or cutting scope intelligently
- Ensure the team ships working software regularly, not perfect software eventually
4. Founder and team interface:
- Be the primary interface between the founders and the engineering team on a day-to-day basis
- Translate founder priorities into engineering language and engineering constraints into founder language
- Push back clearly when scope creep threatens delivery, with data and alternatives, not just resistance
- Keep founders informed on progress, risks, and decisions without requiring them to be in every meeting
5. Documentation and knowledge management:
- Ensure product decisions are documented so the team does not relitigate the same conversations repeatedly
- Maintain a clear record of what was built, why it was built that way, and what was deliberately left out
- Build a culture of written communication in a distributed async team
Requirements:
1. Technical:
- You have managed technical products in e-commerce, SaaS, or complex backend systems before
- You can read and understand technical architecture decisions without needing them explained from scratch
- You write specs that developers ship from directly, not specs that generate ten clarifying questions before work starts
- Comfortable with Agile methodologies, you adapt the process to the team rather than forcing the team into the process
- Familiarity with API-first architectures, data modeling concepts, and distributed systems at a conceptual level
- Experience with project management tools, Jira, Linear, Notion, or equivalent
2. Product thinking:
- You have strong opinions about what makes a product good and you can defend them with user and business data
- You understand the difference between features that users ask for and features that solve real problems
- You have killed features before because the data said to, and you would do it again
- You think in systems, not in isolated features, you understand how one decision affects five other things
3. Mindset:
- Scope creep is your natural enemy and you fight it without apology
- You make decisions with incomplete information because waiting for certainty is not a strategy
- You are comfortable being wrong and changing course quickly when reality contradicts the plan
- You operate with a bias toward action, a meeting that produces no decision is a failed meeting
4. Soft skills:
- Exceptional written communicator, this team is distributed and async, written clarity is how you earn trust
- You listen carefully before forming opinions, but you form them quickly and defend them clearly
- You build genuine relationships with engineers, not a manager-report dynamic
- You stay calm when things break because things will break
5. Language:
Excellent English. Every spec you write, every ticket you create, every async message you send is a communication product. Near-native fluency in English is a hard requirement.
Who we are looking for:
A product manager who has worked in the engine room of a technical product and knows what it actually takes to ship. You have felt the pain of a poorly written spec, a bloated backlog, and a roadmap that nobody believes in, and you have fixed all three before. You thrive in early-stage environments where the product is still being defined and the team is lean. You want to own the product process of something ambitious from the ground up and build a way of working that scales as the team grows. You are not here to manage, you are here to ship.
