Senior / Principal Embedded Firmware Engineer

Livingston

£50,000 - £75,000

Hybrid Working – regular time on-site working closely with hardware and lab-based systems

Job Overview:

An established engineering SME is looking for a Senior / Principal Embedded Firmware Engineer to play a key role in the development of advanced real-time control systems.

The company designs and builds high-performance electronic systems used in demanding, safety-critical environments. You’ll be working on complex, multi-disciplinary products where firmware is central to performance, reliability, and system behaviour.

This is a hands-on role working closely with electronics, systems, and control engineers, with real influence over architecture, technical direction, and long-term product development.

Key Responsibilities:

• Develop real-time embedded firmware in C for microcontroller and DSP-based platforms.
• Take ownership of firmware design across the full lifecycle: requirements, architecture, implementation, testing, and validation.
• Work closely with electronics and systems teams on board bring-up, integration, and lab-based testing.
• Support system-level design decisions and contribute to overall product architecture.
• Develop robust, scalable firmware for high-reliability environments.
• Contribute to engineering best practices including testing, documentation, and continuous integration.
• Provide technical guidance to other engineers and support project delivery where required.

Experience:

• Strong commercial experience developing embedded firmware in C.
• Deep understanding of real-time embedded systems and low-level architecture.
• Experience working with microcontrollers or DSP-based platforms.
• Strong knowledge of embedded interfaces (SPI, I2C, UART, CAN, Ethernet).
• Experience with system integration, hardware bring-up, and debugging in lab environments.
• Comfortable working across multiple workstreams and contributing to technical planning.
• Experience at Senior or Principal level, with the ability to influence technical direction.

Nice to Have:

• C++ for embedded systems
• Python or C# for tooling or test development
• RTOS experience and deterministic real-time systems
• ARM-based microcontrollers (e.g. STM32) or DSP platforms
• MATLAB / Simulink
• CI/CD, unit testing, and scalable firmware architecture
• Secure firmware design (secure boot, OTA updates, encryption)
• Experience with connected or networked embedded systems
• Background in high-reliability, control systems, or power-focused hardware
