Job Zusammenfassung
In dieser Position entwickelst du skalierbare Backend-Services in Kotlin/Java, gestaltest APIs für LLM-Integration und verbesserst die Systemstabilität sowie Testmethoden über den gesamten Lebenszyklus hinweg.
Job Technologien
Deine Rolle im Team
- 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.
