- 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

- 5+ years of experience with Java 21+ and Spring Boot

- 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)
