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)
