An established IoT consultancy is looking for a Senior 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 or 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

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. Good understanding of embedded development processes. Clear communication skills and a collaborative approach. Able to work independently and deliver reliable, well-tested code.
