Activities

We are looking for a backend specialist who loves the intersection of stability and scalability. Your focus will not be on a title, but on the impact of your code. You will:

• Bridge Systems: Build and maintain robust microservices that ensure seamless communication between internal and external environments.
• Drive Implementation: Take full ownership of features from a raw idea to a production-ready deployment.
• Evolve the Architecture: Contribute to our technical roadmap by questioning the status quo and proposing scalable solutions.
• Secure the Flow: Implement and refine authentication and authorisation flows (OAuth, Auth0) to keep our systems safe and accessible.
• Optimise the Core: Ensure our data layer is lean and fast, applying deep knowledge of SQL and PostgreSQL to solve complex data challenges.
  
  

Team

• Ownership over tickets: You’re trusted with real responsibility, not just tasks. No unnecessary bureaucracy, no micromanagement – we rely on you to take things forward.
• Build > Talk: We test what works – not what sounds good. Fail fast, learn faster.
• High standards, low ego: We take our work seriously, but not ourselves. Direct feedback, honest collaboration, no drama.
• Stay sharp: Hackathons, conferences, community – we invest in your growth and keep you at the cutting edge.
• And yes – the fundamentals are covered too: 30 days of vacation + Dec 24 & 31 off, Smart Fridays (4 days week possible), mobility (Germany ticket & JobRad), sports & health offerings, mental health support, corporate benefits, RTL+ access, and more.
