What your work will look like:
- Design, build, test, and operate cloud-based microservices (Java/Spring Boot, Kafka)
- Write automated tests (unit, integration, and end-to-end) as an integral part of your daily work
- Contribute to product design by writing technical specifications – clear enough to
guide both engineers and AI agents
- Use AI-assisted development (coding agents, AI code review, spec-driven workflows)
in your daily work and help us evolve how we use it
- Work with the Unzer Tech standards and processes and help us improve them
- Be actively involved in team and organizational knowledge-sharing
What you need to be successful in this role:
- 5+ years of experience with Java 21+ and Spring Boot
- Solid knowledge of data structures, algorithms, operating systems and distributed systems
- Experience with SQL databases (schema design, migrations); NoSQL is a plus
- Experience with microservices, event-driven messaging (Kafka, Avro) and
Git-based workflows (feature branches, pull requests, code review)
- You diligently test (ideally test-first/TDD) and document your deliveries
- Experience in architecture design (e.g. Domain-Driven Design) and common design patterns
- Experience with observability tools such as Coralogix or OpenTelemetry
- Hands-on experience with AI coding assistants/agents (e.g. Claude Code, GitHub Copilot):
you use them productively and critically review, test and own the code they produce
- Hands-on mentality
Nice to have:
- Frontend experience with Angular
- Know-how in delivering software to the AWS cloud platform
- Experience with Docker, Kubernetes and GitOps (e.g. Argo CD)
- Experience building agentic workflows (MCP integrations, custom agent skills,
AI steps in CI such as automated PR review)
- Experience in regulated environments (payments, PCI-DSS, GDPR)
