Backend Engineer

Annual releases gave way to two-week sprints years ago, and the platform now handles over 200 million API calls a day. Marblebound Labs employs 700 people across engineering hubs in Berlin and three other locations, building ERP software for mid-market manufacturers. Most engineers work remotely and come into the office one week a quarter for planning.

Job summary:

This role opened up after a team member moved internally. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. Backend role focused on API design, data modelling and making slow things fast. This role is fully remote within Germany.

What you'll do:

• Review code for correctness, performance and failure handling.
• Tune slow queries, add indexes and read query plans.
• Secure endpoints with OAuth 2.0, JWT validation and proper input checks.
• Instrument services with metrics, structured logs and OpenTelemetry traces.
• Add caching with Redis where it actually helps, and remove it where it doesn't.

What you'll need:

• 3+ years of backend development experience in a production environment.
• Strong SQL and relational data modelling skills.
• Working knowledge of message queues or streaming platforms.
• Proficiency in at least one of Go, Java, Kotlin, Python, C# or Node.js.
• Experience designing and versioning HTTP APIs.

Perks and benefits:

€81,000 - €93,000 a year
