Qualifikationen

You have strong proficiency in Go and deep understanding of distributed systems and service-oriented architecture. You are comfortable with JavaScript/TypeScript, or confident you can pick up Node.js quickly - with strong Go fundamentals, we expect the rest to come easily. You've worked on a team that builds and maintains a native mobile app. You don't need to write native code yourself, but you have real exposure to how mobile apps consume backend services and understand the constraints and caveats they introduce (API design for mobile, versioning and backwards compatibility, release cycles, latency, offline behaviour). You can spot when a backend decision won't fit the app and flag it early. You are well-versed in SQL and relational database design. You have general knowledge of the frontend world, and are able to perform basic tasks in our frontend apps. You're a self-starter with strong ownership, initiative, and the ability to quickly learn and navigate complex systems. You're open-minded and communicate with clarity, directness, and respect. You value humility, are low-ego, and thrive in a collaborative, transparent culture. You have excellent English skills and you are based in a European time zone. You are curious and eager to experiment with new and better ways of developing software, whether it's a new framework, the latest AI tool, or developing a new practice. Bonus: you're comfortable operating beyond your own squad - reviewing designs and guiding other engineers whose work touches the mobile app. This role has room to grow into a broader technical leadership scope for the right person. Erfahrung

You have 7+ years experience designing and building scalable backend services in a modern production environment. Existing Node.js experience is a plus. Ausbildung
