Job description

Social network you want to login/join with:

Imagine joining a company where your ideas shape the future of intelligent LED lighting cabin technologies working for some of the biggest names in commercial aviation. Where you're trusted with autonomy, encouraged to collaborate closely with hardware and electronics engineers, and given the freedom to lead a new project from the ground up.

It's an opportunity to be part of a small, close-knit team that values flexibility, innovation, and a family-like culture. You'll play a key role in developing advanced lighting and safety systems for high-reliability environments, with real-world impact across the commercial aviation sector.

As an Embedded Software & Firmware Engineer, you'll be hands-on with cutting-edge embedded solutions that prioritise both performance and sustainability. Designing systems that reduce environmental impact through energy-efficient operation.

This is a hybrid role, requiring a minimum of 4 days per week on-site at the South Wales office.

What You'll Be Doing

• Designing and implementing embedded software and firmware for microcontrollers and programmable logic devices
• Developing low-level drivers, communication protocols, and real-time control logic
• Writing efficient, maintainable code in C/C++
• Contributing to system architecture, requirements definition, and hardware integration
• Debugging and resolving firmware issues across development and production
• Supporting secure firmware update mechanisms and bootloaders
• Participating in verification and validation activities, including unit and system testing
• Maintaining clear technical documentation throughout the development lifecycle
• Collaborating closely with hardware, systems, and QA teams

What We're Looking For

• A degree in Computer Science, Electronics, or a related field
• Solid experience in embedded software/firmware development
• Proficiency in C/C++ and experience with real-time or bare-metal systems
• Strong understanding of microcontrollers and digital communication protocols (I2C, SPI, UART, CAN)
• Confidence using lab tools such as oscilloscopes and logic analysers
• Familiarity with version control systems (e.g., Git) and Agile development practices
• Experience with safety-critical or high-integrity systems (e.g., aerospace, automotive)
• Exposure to FPGA development or low-level hardware programming
• Understanding of CI/CD pipelines and automated testing

What You'll Get in Return

• 25 days annual leave + 8 bank holidays
• Christmas shutdown
• 5% company pension contribution
• Annual bonus scheme (based on company and individual performance)
• Early finish Fridays (1pm finish)
• Free annual eye test
• Cycle to work scheme
• Employee Assistance Programme (EAP)

You'll be joining a supportive and technically capable team that values clear communication, practical problem-solving, and continuous improvement. The company offers flexible working arrangements and encourages ongoing professional development.
