Senior C++ Developer

Senior C++ Software Engineer (MedTech) - Contract | Germany | Long-Term Project

We're supporting a leading medical device company on a long-term software development programme focused on improving and modernising an existing, market-released product.

The successful engineer will work within a mature codebase, identifying technical limitations, refactoring existing components, and implementing sustainable software design improvements that support future scalability and maintainability.

Responsibilities

• Analyse existing software systems and identify areas for improvement
• Refactor and redesign legacy components to improve maintainability and performance
• Implement modern software design principles within an established architecture
• Collaborate with senior designers and architects to deliver long-term product improvements
• Contribute across multiple layers of the application, from core libraries to UI components
• Work within a regulated medical device development environment

Required Experience

• Strong commercial experience with C++ (modern C++, ideally C++20)
• Proven experience developing applications using Qt and QML
• Ability to work within large, complex codebases and improve existing systems
• Strong understanding of software design principles, architecture, and engineering best practices
• Experience refactoring and modernising legacy software
• Comfortable working across backend, middleware, and UI layers
• Experience within medical devices or another regulated industry

Nice to Have

• Perforce version control experience
• Experience with Qt Creator, QBS, Jenkins, and Jira
• Embedded Linux experience
• Familiarity with AI-assisted development tools

Ideal Profile

• Design-minded engineer rather than a feature-focused developer
• Able to understand architectural trade-offs and long-term product considerations
• Experienced in improving and stabilising production software
• Comfortable working in highly regulated, quality-driven environments

If you're an experienced C++/Qt engineer who enjoys solving complex technical problems and improving existing products rather than building from scratch, I'd be keen to discuss the opportunity further.
