• 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:
