📋 Description

• You are the technical point of contact in the development team: you actively code, make technical decisions in day‑to‑day work and support colleagues through technical mentoring, without having disciplinary management responsibilities. • Actively contribute as a developer during the sprint, including implementing your own features and bug fixes. • Take on more complex technical tasks and resolve architectural challenges in everyday team work. • Participate in architecture decisions within the team, for example around modularization, interfaces and security. • Actively contribute to the further development of our core systems (C#/.NET, MS SQL) toward resilient, containerized services in a Kubernetes cluster. • Consider non‑functional requirements such as observability, performance, scalability, security and deployment. • Actively help expand and optimize CI/CD pipelines (GitHub Actions, ArgoCD, Azure DevOps) and establish Clean Code, code reviews and automated tests (unit & system tests) with a clear shift‑left mindset. • Contribute to shorter development cycles and more reliable deployments within the team. • Promote knowledge sharing instead of siloed expertise: ensure that knowledge is accessible across the team, documented and not bound to individual persons. • Work on structured, understandable and up‑to‑date process and system documentation. • Develop practical best‑practice guides and technical standards with a focus on quality and efficiency. • Provide technical guidance and coaching to developers in the areas of architecture, Clean Code and systems thinking, without disciplinary responsibility. • Support onboarding of new team members through technical input and knowledge transfer. • Encourage continuous learning and constructive technical exchange within the team. • Closely coordinate with the Engineering Manager on technical questions and the team’s technical direction.

• C#/.NET experience and solid backend knowledge • Several years of experience with web applications in C#/.NET • Confident experience with scalable database systems (MS SQL, PostgreSQL) and modern backend architectures (modular services) • Ideally experience with Angular (v15+) and RabbitMQ • High quality standards without a quick‑fix mentality, combined with pragmatism and a holistic product mindset • Experience with AI / large language models (LLMs) in development • Experience integrating new technologies and digital solutions • Solid understanding of the capabilities and limitations of AI in an enterprise context • Experience in AI/LLM‑assisted development and ideally in integrating AI‑based features • Hands‑on experience with Docker / Kubernetes, fully automated deployments and Infrastructure as Code • Strong expertise in designing, scaling and orchestrating services • Routine in using GitHub, Azure DevOps, CI/CD pipelines (GitHub Actions, ArgoCD) and automated tests (unit & system tests) • Enjoy sharing your technical knowledge and helping other developers grow • Ability to explain complex technical topics clearly, including to non‑technical stakeholders • Interest in understanding the business and actively participating in discovery processes with product managers and stakeholders • Languages: English at least C1 (team), German at least B2 (stakeholders)
