Job Description

Welcome to our API squad! We’re just your friendly bunch of code wizards, crafting microservices, slaying SQL dragons, and keeping our systems safe from chaos. Join the party and help us level up! You’re not just coding APIs – you’re unlocking achievements in a high-paced, ever-changing arena. Be part of a small but mighty squad (currently 3 devs → soon +2). Knowledge-sharing culture & frequent code reviews = constant XP boost. Ownership of your code: monitoring, greenkeeping, improving. Hybrid playstyle: work remote, but meet IRL in Berlin HQ at least once a week. Work on complex systems where your input actually changes the meta.

Job Responsibility

  • Develop and maintain microservices that connect worlds (internal & external systems)
  • Command side quests (and sometimes the main questline) when the Tech Lead is away from keyboard
  • Shape the team’s strategy with your strong opinions and battle-tested experience
  • Master the arts of authentication & authorization (OAuth, Auth0 integrations, specs reading = your spellbook)
  • Design & optimize SQL databases like a level 99 architect (bonus points for PostgreSQL mastery)

Requirements

  • 5+ years XP as Backend/API Developer in Node.js + TypeScript
  • Legendary SQL & DB design skills (PostgreSQL = epic weapon)
  • ORM wisdom (knowing both the buffs and nerfs)
  • Strong in automated testing (jest/mocha, coverage quests)
  • Docker, Git, JavaScript, SQL – all mastered

Nice to have

  • AWS, Grafana, Prometheus, Graylog
  • Academic background (Computer Science, Software Engineering)
  • Leadership XP (professional, not disciplinary)

What we offer

  • Cutting-edge gear – Mac, Linux, or your weapon of choice
  • Flex mode – hybrid work, flexible hours, and even “Smart Fridays” (4-day week opportunity)
  • Level-up opportunities – trainings, hackathons, conferences & coaching
  • Perks & power-ups – JobRad, Deutschland-Ticket, Urban Sports Club, RTL+ Premium & more
  • Epic guild life – team events, knowledge sharing, and plenty of XP along the way
  • Anniversary Programme
  • Corporate Benefits
  • Gift Matching
  • Mental Health support
  • Referral Programme
  • RTL+ Premium account
  • Social Day
  • Sports support
  • Thank you Programme
