Senior Embedded Software Engineer

A growing international security technology manufacturer is expanding its R&D team. With several new products in development, they need a senior embedded engineer to lead architecture decisions, get hands-on with hardware and help shape the next generation of their technology.

• Lead embedded architecture and system-level design for new and existing products
• Develop real-time C/C++ firmware under tight timing and memory constraints
• Build peripheral drivers (SPI, I2C, UART, USB, DMA, Ethernet) and bootloaders
• Configure and optimise RTOS scheduling, memory and ISRs
• Lead board bring-up, hardware debugging and validation
• Ensure designs meet security, reliability and EMC requirements
• Run design reviews and mentor junior engineers

• 7+ years in embedded electronics engineering
• Expert C/C++ with GCC, IAR or Keil tool chains
• Strong experience with ARM Cortex-M, STM
  32, ESP
  32 or NXP processors
• RTOS and low-power design experience (FreeRTOS ideal)
• Knowledge of embedded security and encryption
• Unit testing, Git and CI/CD experience
• Solid hardware skills: schematics, Altium, debugging and prototyping
• Familiarity with CAN, RS-485, TCP/IP, BLE or Wi‑Fi

This is a genuinely hands-on senior role with real ownership, working across the full product lifecycle alongside an experienced, collaborative team.
