Jobbeschreibung

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.

Responsibilities

• 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 elevate 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

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

Benefits

• Office-first company: Hybrid setup with 3 days in the office and 2 days working from home, offering flexibility in how you structure your work
• Modern, air-conditioned office with plenty of natural daylight
• Central location between Gleisdreieck and Potsdamer Platz with excellent public transport access
• Spacious rooftop terrace with stunning views over Berlin
• Full coverage of a Germany-wide public transport ticket
• Dog-friendly office – we’re happy to welcome four-legged team members
• Corporate benefits platform with attractive offers and discounts across many brands
• Company pension scheme with a 20% employer contribution – we invest in your future
• Regular company and team events to strengthen collaboration and team spirit
• After-work fun: Nintendo Switch, PS5, darts, and table football
• Free drinks, fresh fruit, and muesli available at all times
