Senior C++ Engineer – Multithreading (f/m/d)

As the leading company in the field of software solutions for healthcare, we operate in 19 countries and employ over 9,000 dedicated staff members. You will work in a dynamic and innovative environment full of opportunities. With your commitment and passion, you have the chance to make a sustainable difference.

CGM Leverages AI: We’re looking for people who feel the power of AI in the healthcare environment, who want to help shape change, and who are driven by a curious passion to see how technology can make healthcare smarter, simpler, and better.

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!

Are you passionate about groundbreaking products? Do you have the talent to turn ideas into real, valuable solutions—while always keeping the bigger picture in mind? Then we’d love to meet you!

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.
