About you

You enjoy working on and improving complex safety-critical systems. You’ll have a good understanding of either Linux, MCU or test engineering and care about writing clean, reliable code. You’ll be a strong collaborator and communicator who’s happy to work closely with developers. You’ll also be interested in the full development lifecycle and in working to standards like IEC 62304.

Your skills and experience

Whilst you do not need to meet all of these points, please ensure you meet the majority within your specialism before making an application.

Essential

• Around 3–5 years’ experience in embedded software development
• Strong C and/or C++ skills
• Solid understanding of hardware–software interfaces, embedded architectures, or test automation frameworks
• Experience with system-level integration, debugging, or verification
• For Senior Engineer positions, you'll also bring experience leading technical workstreams, influencing architecture decisions and mentoring other engineers. You'll be comfortable balancing hands-on development with technical leadership responsibilities and helping teams deliver high-quality, compliant software solutions.

Salary

• For these roles we are considering salaries of up to £53,000 (or up to £73,954 for Senior Engineers). As part of your application, we will ask you to state your desired salary. If you would like to discuss your salary expectations in more detail, please reach out.
