Together, we are shaping the healthcare system of the future. Become part of our mission and make a difference for a world where knowledge saves lives!

Your Impact

• You design and develop high-end C++ components for our medical desktop applications, with a strong focus on performance, stability, and scalability.
• You architect, implement, and review complex multithreading and parallelization concepts to ensure efficient, safe, and responsive execution in everyday clinical use.
• You analyze, refactor, and optimize our large existing codebase (QT, CMake, Conan, MSVC, and embedded CEF), identify bottlenecks, and systematically raise the performance and quality of long-lived products.
• You work closely with Architecture, QA, and Product Management, drive the modernization away from legacy MFC / ATL / Win32 and Delphi towards modern C++ and current .NET, and actively raise the overall C++ engineering bar.
• You use AI agents and tools like Claude Code in your daily work to accelerate refactoring, code analysis, and legacy modernization, and you continuously improve our shared agents, skills, and workflows.

Your Profile

• Several years of senior-level experience in professional C++ development, ideally in high-performance, highly parallelized desktop systems with significant ownership and end-to-end responsibility.
• Excellent academic background with a completed university degree in computer science, mathematics, physics, electrical engineering, or a comparable technical discipline with very good grades.
• Deep expertise in modern C++ (C++ 14/17/20), multithreading and concurrency, debugging and performance tuning, plus hands-on experience with Qt, CMake, Conan, MSVC, and integrating components such as CEF; confident, effective use of AI in software engineering, ideally including Claude Code or similar agentic coding tools as well as AI pipelines and context engineering.
• Fluent German and fluent English, both in spoken communication and in writing, enabling you to work seamlessly in cross-functional, international teams and with German-speaking stakeholders.
• A structured, analytical way of working, high-quality standards, strong problem-solving skills, innovation drive, proactive ownership and a pronounced sense of entrepreneurship with genuine enthusiasm for shaping the future of healthcare IT.
