## About the Role

* 4+ Jahre Produktiv-Erfahrung mit TypeScript im Frontend und Backend
 * Solide Next.js / React-Kenntnisse und mindestens ein Node-Backend-Framework (Fastify oder Nest)
 * Routine mit PostgreSQL, einem ORM (Drizzle/Prisma) und Redis-basierten Queues
 * Grundverständnis von Docker und Kubernetes - kein SRE-Niveau, aber kubectl describe schreckt dich nicht ab
 * Klare Meinungen zu API-Design, Type Safety und wo Validierung hingehört
 * Pragmatische Haltung zu KI-Tooling - weder Hype-getrieben noch allergisch

 * Drizzle-Migrations, Zod-First-API-Verträge, OpenAPI 3.1
