Senior Embedded Firmware Engineer
Salary: Up to £85,000 plus equity
Location: Fully remote, UK wide (company events in Cheshire)
This is not one of those roles where you inherit a dusty codebase and a twelve month backlog of bug tickets. It's a genuinely novel piece of engineering in one of the most consequential sectors in the country, and our client is after a proper seasoned firmware engineer to take the technical lead on the device side.
The opportunity
Our client builds intelligent connected hardware for the energy sector: devices at the very edge of the grid that talk to all manner of third party equipment over multiple radios and wired protocols, reporting securely back to the cloud. The engineering team is deliberately small and exceptionally senior, and they've invested heavily in AI driven development pipelines to accelerate the build. They don't want an army; they want a handful of very capable engineers who can steer those tools intelligently and bring the deep hardware understanding no model can replace.
The technology
ESP32 handling comms: WiFi and BLE now, Thread next, multi radio beyond that
Multiple RP2040 class microcontrollers running the bulk of the application firmware
A dedicated processor acting as security firewall and orchestrator
STM32 class parts, FreeRTOS, embedded C with some C++
SPI and UART between processors, MQTT with mutual TLS to the cloud, Modbus to third party kit
A substantial codebase, already around 300,000 lines
The role
You'll lead the build out of the device firmware, taking ownership of the meaty, low level problems that sort the seasoned from the merely enthusiastic: SPI bus behaviour, timing across processors, tight memory footprints, radio coexistence and field reliability. You'll set standards, mentor the wider team and have a real say in where the platform goes next.
What you'll bring
Strong embedded C on resource constrained microcontrollers
FreeRTOS or comparable RTOS experience
Real depth in hardware facing debugging with scopes and logic analysers
Wireless connected device experience; ESP32, BLE, WiFi or Thread
MQTT, TLS and secure device to cloud communication
An open mind towards AI assisted de...
