Job description

Are you an Embedded Software Engineer with 2+ years' experience looking for your next challenge?

I'm working with a globally leading engineering business that is expanding its innovative embedded software team, working on high-reliability systems and technically challenging projects. The working split is three days per week onsite and two from home.

What makes this opportunity particularly interesting?

You won't be boxed into one area of embedded development. With projects spanning the full embedded software stack - from low-level C through to higher-level C++ and Linux-based systems - the team can shape the role around your experience and technical interests.

Hybrid - Southampton (3 days onsite and 2 from home)

What you'll be working on:

• Developing and maintaining embedded software using C/C++
• Designing, testing and integrating software for complex embedded systems
• Working across the full software development lifecycle
• Collaborating closely with hardware, FPGA and systems engineers
• Developing robust, reliable and high-performance software
• Working on technically challenging projects within a high-reliability engineering environment

I’m interested in engineers with experience in:

• Embedded Software Development
• Object-Oriented Design (OOD), SOLID principles or design patterns
• Unit testing and modern software development practices
• Communication protocols such as CAN, RS232/RS422, UDP, TCP/IP or equivalent
• 2+ years of relevant industry experience

Experience in any of the following would be a bonus:

• MATLAB / Simulink
• OpenGL / Vulkan
• CUDA / OpenCL
• FPGA or HDL exposure
• Video processing or machine learning
• Defence, aerospace, automotive or other high-reliability industries

Please note: Due to security requirements, applicants must have lived in the UK for at least the last five years.

Why consider it?

If you're an embedded engineer who wants to work on genuinely interesting technology, broaden your experience across the embedded stack and join a team where your technical strengths can help shape your projects, this could be a great next step.
