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

This role focuses on Matomo Core, the foundation of the open-source analytics platform that open-source users, cloud customers and the plugin ecosystem depend on. As a Product Engineer, you will own problems end-to-end rather than tickets: understanding customer problems, shaping priorities, building across the stack, shipping incrementally and measuring outcomes. You will work on a mature, technically complex codebase, improving security, performance, scalability, reliability and data accuracy while evolving APIs, privacy and consent handling, and analytics capabilities. The position sits in a newly formed European team, where you will help shape how the team works and where Core can create the greatest impact, using AI as part of your everyday engineering workflow.
