Full Stack Product Engineer (100% Remote - Germany | UK | Ireland)

Help build the open future of digital intelligence. At InnoCraft (trading as Matomo), we believe everyone has the right to data sovereignty, privacy and trusted analytics insights. Born from open source and backed by a global community, Matomo helps organisations understand their users and digital performance without surrendering ownership, privacy or control of their data. Today, Matomo is used on more than one million websites across 190 countries, supporting leading brands, national governments, universities and organisations in regulated industries.

We are looking for a Product Engineer to help organisations make sense of their digital performance as AI changes how people discover and interact with them. You’ll help decide which problems matter most, shape solutions and deliver software that gives customers clearer insights while protecting their privacy and ownership of their data. Working closely with Product and your engineering team, you’ll have the trust and responsibility to take ideas through to measurable customer outcomes. This is an opportunity to take real ownership, solve challenging product and platform problems, and see your work make a difference in a widely used open-source product.

Why this role matters

Customers need confidence in their data, a clear understanding of their users and tools that help them act on what they learn. As digital behaviour changes, Matomo needs to meet those needs while remaining accessible to smaller organisations and capable enough for demanding enterprise use. Our Product Engineering teams focus on five domains: Measurement Integrity, Human Analytics, AI Analytics & Digital Presence, Growth & Web, and Enterprise Platform. You’ll work within one of these domains, collaborating across teams where customer problems and technical decisions overlap.

You’ll build new capabilities and improve a mature, widely used product. That means understanding existing systems, choosing practical solutions and evolving Matomo with care for the customers, open-source users, integrations and plugins that depend on it.

Your work will directly influence:

• The accuracy and trustworthiness of the data customers use to make decisions.
• How clearly customers understand human behaviour and their digital presence as AI changes how people discover and interact with them.
• How easily customers get started, find value and grow their use of Matomo.
• How effectively enterprise customers manage access, governance and integrations at scale.

We make extensive use of approved AI tools throughout our engineering workflow, from exploring ideas and prototyping to building, reviewing and testing software. We expect you to use them to move faster and improve quality, while applying your own judgement and taking responsibility for the decisions you make and the software you ship.

What you’ll own

• Understand the problem. Work with Product, colleagues and customers to uncover needs, question assumptions and agree what a useful outcome looks like.
• Shape the solution. Explore options, test ideas through prototypes and make clear trade-offs about scope, complexity and what to deliver first.
• Build across the stack. Own the technical design and implementation, choosing practical solutions that fit the product and its existing systems.
• Build quality in from the start. Work with QA and Design as needed, considering privacy, security, accessibility, performance and compatibility throughout delivery.
• Deliver and learn. Ship in small increments, take responsibility for how your changes work in production, and use customer feedback and evidence to measure results and improve them.
• Use AI effectively throughout delivery. Give tools the context they need, challenge their suggestions and verify the results. Keep privacy, security and maintainability central to the work you ship.

What you bring

• 5+ years experience delivering full-stack software, with the technical depth to investigate difficult problems and make sound design decisions.
• Product judgement and a drive to solve real customer problems. You can explain why a change is worth building and care whether people use and benefit from it.
• Confidence taking ownership of outcomes, clarifying problems and shaping solutions without needing every requirement spelled out in a ticket.
• Confidence working in mature systems, understanding existing behaviour and improving it without unnecessary rewrites.
• The ability to balance delivery speed with quality, privacy, security and backwards compatibility.
• Strong experience using AI throughout development: refining requirements, preparing clear context for prompts, building and testing solutions, and checking the results. You keep reusable AI skills and instructions up to date, follow developments in models and tools, and experiment with new ways to improve delivery and quality.
• Strong written and spoken English, with the ability to communicate clearly in a global, asynchronous environment.
• A strong record of taking ownership, exercising sound judgement and delivering measurable outcomes.

Helpful experience

• You are happy working wherever the problem takes you: frontend, backend, databases, APIs, product flows, documentation, or customer feedback.
• Our stack includes PHP, MySQL, JavaScript, Vue.js, and TypeScript. Exact stack experience is useful, but not required. We care more about your ability to learn, reason, ship, and solve meaningful problems.
• Experience in product management, UI/UX design or building your own product or business.
• Contributing to or maintaining open-source projects, or building plugins, APIs and integrations used across different environments.
• Analytics, data-intensive systems or enterprise software.

You may not match every item, but you should bring strong capability in the core requirements and a clear record of creating meaningful impact.

Why Matomo?

Matomo is for people who want their work to matter. You will help build technology that protects data privacy, strengthens digital sovereignty and gives organisations a genuine alternative to surveillance-based platforms. We are intentionally lean, globally distributed and backed by a worldwide open-source community. Important work is not buried under layers. You will have access to meaningful problems, the context behind decisions and the opportunity to influence what Matomo becomes next.

We value people who take ownership, exercise strong judgement and turn complex problems into clear, valuable outcomes. People who raise standards, challenge assumptions and care about the complete result, not only their part of it. High performance at Matomo means choosing the work that matters most, moving it forward with urgency and leaving customers, colleagues and Matomo stronger because of your contribution.

You will have freedom over where and, within the needs of your role, when you work. In return, we expect clear communication, dependable follow-through and accountability for outcomes.

We also protect focused work through:

• No-meeting Fridays
• No more than two days each week with late meetings
• No meetings after 10pm in any time zone

This is a place for people who want meaningful responsibility, visible impact and the opportunity to help build something globally significant.
