We're seeking an Embedded Software & Firmware Engineer to join a team developing advanced lighting and safety systems for high-reliability environments. The role involves working on embedded solutions that power intelligent cabin technologies used across commercial aviation sectors.

You'll be contributing to projects that combine innovation with sustainability - including systems designed to reduce environmental impact through energy-efficient operation and eco-conscious materials. This is a hands-on engineering role with real-world impact, ideal for someone who enjoys solving complex technical challenges and working closely with hardware.

This will be a hybrid role with a minimum of 4 days a week in the office which is based in South Wales.

What you'll do:

• Design and implement embedded software and firmware for microcontrollers and programmable logic devices.
• Develop low-level drivers, communication protocols, and real-time control logic.
• Contribute to system architecture, requirements definition, and integration with hardware.
• Debug and resolve firmware issues across development and production stages.
• Support secure firmware update mechanisms and bootloaders.
• Participate in verification and validation activities, including unit and system testing.
• Maintain clear technical documentation throughout the development process.
• Work closely with cross-functional teams including hardware, systems, and QA.

What you'll need:

• 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).
• Confident 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:

• 25 days annual leave plus 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
