Your tasks

• Design & Development: You will design and implement high-performance microservices in Go – idiomatic, testable, and production-ready. You will use modern development tools, including AI-powered tools, to improve quality and speed.
• Architecture : You actively participate in the design of event-driven architectures (including REST and gRPC interfaces), adhere to established messaging patterns (idempotent consumers, dead message queues), and document architectural decisions as ADRs.
• DevOps & Operations: Following the principle "You build it, you run it," you are responsible for the entire technical lifecycle of the software, Kubernetes deployments on our STACKIT cloud, as well as monitoring, structured logging, and tracing of your services. You define SLOs (Service Level Objects) together with the product and team.
• Teamwork: You derive technical requirements from user stories and conduct code reviews.
