• 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
• Death in service benefit
• Annual bonus scheme (based on company and individual performance)
• 37.5-hour work week
