We are looking for an experienced Software Engineer, specialized in C++, to strengthen our growing
software engineering team. In this role, you will contribute to the entire software development
lifecycle—architecting, coding, testing, and deploying—while ensuring performance, reliability, and
reusability. You will collaborate closely with cross-functional teams and help shape best practices
within our entire organization.

Your tasks and responsibilities

• Design, develop, and maintain efficient, reusable and reliable cross-platform C++ components and applications.
• Collaborate with cross-functional teams to define, design, and ship new features.
• Write unit tests and integration tests to ensure code quality and reliability.
• Participate in code reviews and contribute to the improvement of coding standards.
• Contribute to the system design process.
• Troubleshoot and debug applications to identify and resolve issues.
• Stay up-to-date with the latest C++ standards and software development best practices.
• Contribute to the development of technical documentation and user guides.
• Mentor junior developers and contribute to best practices in coding and architecture.

You don’t need to tick every box — the more you bring, the better, but we value curiosity and
continuous growth just as much as experience.

Your profile

• Master degree in Computer Science, Software Engineering, or a related field (or equivalent
  through experience).
• 5-10 years proven experience as a C++ Developer or similar role.
• Strong proficiency in C++ programming, including modern C++ standards.
• A working knowledge of python, bash and/or other scripting languages.
• Experience with object-oriented design and design patterns.
• Familiarity with software development tools (git, CI/CD, unit testing frameworks).
• Knowledge of build systems and support tools like Conan and CMake.
• Experience with cross-compilation and multiple platform support.

What We Offer

• Congestion-free working environment with flexible hours, including the option to work up to 2 days at home depending on the job content.
• Engaging team activities with friendly colleagues.
• Varied job in a stimulating, high-tech working environment.
• Continuous opportunities for personal and professional development.
• Permanent position with a market-based salary, supplemented with company benefits
  including a car.
