Currently we are looking for an experienced Senior Embedded Software Engineer to support the development of next-generation chemical and explosive trace detection products. This is a highly technical, hands-on role involving embedded C++ development for ARM Cortex-M33 microcontrollers, hardware integration, and collaboration with a multi-disciplinary team of engineers and scientists.

This assignment will be a 12-month engagement, inside IR35, with flexibility for hybrid working. However, the consultant must be commutable to Hertfordshire as onsite attendance may be required at short notice (within 24 hours) to work closely with target hardware and attend design reviews.

Key Responsibilities

• Design, implement, test, and integrate embedded software in C++20 on ARM Cortex-M33 with FreeRTOS.
• Bring-up and interface with hardware: SPI, I²C, UART, CAN, USB, FRAM, LCD, sensors/actuators.
• Contribute to system architecture and design (UML where appropriate), code reviews, and rigorous debugging (including JTAG).
• Collaborate with electronics, mechanical, and science teams to deliver robust and secure embedded solutions.
• Support lab and field testing of prototypes and production hardware.
• Use Jira for planning/defect tracking and MCUXpresso IDE for development.

Essential Skills & Experience

• 5+ years’ embedded software development in C/C++.
• Strong knowledge of ARM Cortex-M33 / Armv8-M and embedded system design.
• Experience with FreeRTOS (or similar RTOS such as Keil RTX, ThreadX).
• Practical experience with hardware interfaces (SPI, I²C, UART, CAN, USB).
• Skilled with embedded IDEs such as MCUXpresso, Keil uVision, STM32CubeIDE, or CodeWarrior.
• Hands-on debugging (JTAG) and software bring-up.
• Eligible for BPSS on start and capable of obtaining SC clearance.
• Must be commutable to Hemel Hempstead, with flexibility for hybrid work but able to attend site within 24 hours’ notice.

Desirable

• Modern C++20 techniques (smart pointers, RAII, adapter patterns, polymorphism).
• TDD experience and use of UML for design/architecture.
• Knowledge of DMA/cache consistency, linker script/scatter-file modification, and ISR configuration.
• Experience developing embedded GUIs and companion PC applications.
• Security-aware software development.
• Familiarity with state machine design for device workflows.
