Jobbeschreibung

Company Description

Remote in our day-to-day work. On-site when it matters.

We work remote by default – focused, efficient, and with full ownership. For larger features, architectural decisions, and real brainstorming sessions, we come together in Berlin – fast, hands‑on, and without unnecessary meeting overhead.

We use AI to accelerate – not to replace thinking.

We design the system, steer the output, and take responsibility for what we ship.

Fast where it makes sense. Careful where it matters.

Job Description

Your mission

• 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).

Qualifications

Your skills

Must-haves:

• 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-haves:

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