We are building a modern billing platform to replace a 12 year old billing solution used by Corporate & FI customers across the group. The new platform will be cloud-native, hosted on AWS and deployed to our Kubernetes environment. It is being developed with a Java Spring backend, Angular frontend and PostgreSQL.

Lead a small engineering squad (you + 2 developers) and work closely with 2 BAs, QA/test automation and DevOps.
Hands-on development in Java Spring; design and maintain REST APIs/OpenAPI specs (API-first).
Drive Spec-driven Development workflows (SpecKit/bMAD), introduce AI-assisted tools for spec, code and test generation.
Define and enforce CI/CD, observability, security, performance and deployment patterns for AWS + Kubernetes.
Perform code reviews, mentor team members, run architecture / design sessions and coordinate with stakeholders.

Your core competencies:
University degree in Computer Science or equivalent experience.
8+ years software development experience; 3+ years as a technical lead / software architect.
Strong expertise in Java Spring, REST/OpenAPI design, PostgreSQL and cloud-native patterns.
Practical experience with Kubernetes, Docker, AWS and CI/CD toolchains (e.g., GitHub Actions, Jenkins, ArgoCD) and Helm.
Familiarity with Angular (collaborating with frontend), test automation practices and DB design/performance tuning.
Experience with spec-driven development tools (SpecKit / bMAD) or similar is highly desirable.
Proven experience in designing secure, performant systems in regulated environments (banking/payments/billing is a plus).
Fluent English (spoken and written), German is a plus.
