The posting

What You'll Do

Backend engineering at Legal Hero means full ownership. You'll design and run services in our Kotlin/Java stack with Micronaut on AWS, wire LLM capabilities reliably into product flows, harden production systems, and actively shape our testing, deployment, and observability practice — together with a team that takes the craft seriously.

  • Design and own scalable backend services from first commit to production — APIs, data models, versioning, SLOs, and on-call included
  • Build and evolve high-performance, secure infrastructure that handles real load — not just greenfield, but messy reality
  • Wire LLM-powered capabilities reliably into product flows: suggestion APIs, RAG-backed endpoints, agent tool calls — you make AI actually land in production
  • Work closely with frontend, product, and AI teams — your APIs are their foundation, so you design them to last
  • Make the hard tradeoffs: schema migrations, breaking changes, dependency upgrades — with judgment, not just best practices
  • Raise the quality bar through automated testing (unit, integration, end-to-end) and push for architectural improvements that matter
  • Lead incident investigations on your own services, write the postmortem, and escalate only once you have answers

What you bring

  • 6+ years in backend engineering, including 2+ years at senior level
  • Strong proficiency in Kotlin or Java — JVM idioms feel like home
  • Relational databases (MySQL or similar) and at least one public cloud in production, AWS preferred
  • Distributed systems thinking as a reflex: idempotency, retries, eventual consistency, observability
  • Business fluent English; German at B1 or a clear commitment to get there within 12 months

Nice to have — and what you'll pick up here:

  • Micronaut, Kubernetes, AWS Bedrock, LiteLLM, the official Claude Agent SDK, MCP-based architecture
  • Experience with regulated data environments (GDPR, BaFin, §203 StGB)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
