• Developing and delivering embedded software solutions using C/C++.
• Working with microcontrollers, RTOS and embedded systems.
• Translating product requirements and feature requests into clear engineering and software requirements.
• Contributing to system and software architecture across complex electronic products.
• Reviewing and challenging designs throughout development, test and delivery.
• Supporting technology and component decisions, including processors and associated hardware.

• Assessing existing platforms and identifying where new development or architectural changes are required.
• Working closely with electronics, firmware, Product Management, Programme Management, Quality, Manufacturing, Sourcing and Certification teams.

What we’re looking for:

• Strong embedded C/C++ development experience.
• Good experience working with microcontrollers and RTOS.
• Proven experience developing software for complex embedded electronic products.
• Strong understanding of the interaction between software, firmware and electronics.
• Experience translating specifications into clear software/system requirements and technical solutions.
• Strong debugging and hands‑on technical problem‑solving skills.
• The technical credibility to challenge designs and contribute to engineering decisions.
• Experience working within multidisciplinary product development environments.

This contract would particularly suit an experienced Embedded Software Engineer who wants more than a coding‑only role and enjoys having genuine influence over how complex embedded products are designed and delivered.
