Firmware Engineer / Senior Firmware Engineer
Hybrid – Edinburgh (2 days on-site)
Salary: £45,000 - £65,000
Job Overview:
An established embedded systems consultancy is looking for a Firmware Engineer to join their team. You’ll work across a variety of client projects, developing the low-level software that powers real products - from early prototypes right through to production-ready systems.
The work is hands-on, hardware-focused, and offers plenty of technical variety. You’ll be in the office around two days a week for hardware testing, collaboration and project work, with the flexibility to work remotely the rest of the time.
Key Responsibilities:
* Develop firmware in C/C++ for microcontroller-based systems.
* Build and test device drivers, hardware interfaces and real-time features.
* Own tasks across the full lifecycle: requirements, design, coding, debugging and system testing.
* Work closely with electronics engineers during bring-up and prototype development.
* Support technical discussions and help shape solutions with internal teams.
* Senior engineers will take on leadership responsibilities - guiding junior engineers, reviewing code, and helping steer technical decisions on projects.
Experience:
Mid-Level:
* Around 3+ years in embedded or firmware development.
* Strong C or C++ experience.
* Exposure to real-time systems (RTOS or bare-metal).
* Familiar with peripherals and protocols (SPI, I2C, UART, CAN, networking etc.).
* Comfortable working through design, implementation and testing.
Senior:
* 6+ years in commercial firmware or embedded engineering.
* Strong track record of owning features or subsystems end-to-end.
* Experience providing technical leadership, mentoring junior engineers and supporting team delivery.
* Confident in reviewing designs and helping guide technical decisions.
* Comfortable handling client-facing technical conversations.
Both levels:
* Good understanding of embedded development processes.
* Clear communication skills and a collaborative approach.
* Able to work independently and deliver reliable, well-tested code.
Additional Requirements:
* You must already have the right to work in the UK.
* This is a hybrid role - 2 days per week on-site is required.
