The Role

• Design and develop modern end-to-end web applications (frontend, backend, API layer), integrating AI functionality directly into daily workflows.

• Make LLM-based features and AI services productive, from intelligent search to automated workflows, ensuring concepts become stable and secure features.

• Orchestrate AI backends, REST APIs, and data flows into a clean architecture, creating clear interfaces and ensuring reliable, performant, and secure data transfer.

• Ensure quality and scalability by thinking in scalable systems, establishing tests, observability, and monitoring, and taking responsibility for solutions in operation.

• Collaborate with AI/ML engineering, business departments, and product owners on architectural decisions, shaping technical standards in the AI application environment, and elevating the team through knowledge sharing.

What You'll Need

• A completed degree in Computer Science, Business Informatics, Medical Informatics, Mathematics, or a comparable field, with a focus on delivering clean models, code, and architectures.

• Demonstrable experience in integrating AI services and LLM features into productive applications (e.g., via REST, gRPC, OpenAI/Azure OpenAI/similar APIs), and turning prototypes into robust, maintainable interfaces.

• Solid knowledge in connecting REST APIs, data pipelines, and cloud services, with a strong awareness of security, performance, observability, and maintainability.

• A strong ownership mindset, high quality standards, and a passion for sharing knowledge. You communicate confidently in German and English and thrive in interdisciplinary, international teams.
