About this job

About us

Legalhero is the modern platform for legal protection insurance and lawyers. We pursue the ambitious goal of revolutionizing the claims settlement process for legal protection insurance. To this end, we integrate directly into the insurers' systems. Our partner lawyers handle cases highly efficiently and in a customer-oriented manner on our tech platform with the help of AI. Legalhero was founded in 2017 and has helped hundreds of thousands of policyholders to date. Our approximately 90 colleagues are based in Berlin, near the Gleisdreieck.

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

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)
