Senior Embedded Software Engineer
Location: Stroud, Gloucestershire
Salary: Up to £70,000
KO2’s client is an ambitious, well funded and fast-growing technology start-up based in Stroud, developing advanced sensing and monitoring systems that combine low-power embedded platforms, intelligent signal processing, and secure wireless connectivity.
The Role – Senior Embedded Software Engineer
You will be responsible for the full embedded development lifecycle:
* Scoping and requirements definition
* System architecture (hardware & software)
* Simulation and modelling
* Firmware development
* Integration and verification
* Validation and production release
The successful Embedded Software Engineer will work closely with hardware, data, and product engineers to deliver robust, secure, and power-efficient sensing platforms operating in demanding real-world environments.
Key Responsibilities
* Architect and develop low-power embedded firmware (C/C++) for sensor platforms
* Design for ultra-low power consumption in battery-operated and remote systems
* Implement sensor data acquisition and processing pipelines (e.g. MEMS microphones, accelerometers and other environmental sensors)
* Develop and optimise RF communications systems, particularly:
* LoRa or similar LPWAN technologies
* Mesh networking architectures
* Implement secure communications including encryption, authentication and secure boot mechanisms
* Develop machine learning-enabled acoustic detection and classification systems:
* Data pre-processing and feature extraction
* Deployment of optimised ML models on constrained embedded devices
Essential Experience
* Significant experience in embedded C/C++ development
* Strong experience across the full product lifecycle (concept → production)
* Proven expertise designing for low-power embedded systems
* Experience with sensor data acquisition and real-time signal processing
* Strong RF communications experience, particularly LoRa or comparable technologies
* Experience implementing mesh networking protocols
* Solid understanding of embedded security (encryption, authentication, secure firmware updates)
* Strong debugging and hardware bring-up skills
Highly Desirable
* Machine learning for acoustic detection/classification
* Experience with MEMS microphone-based systems
* Wind/ambient noise mitigation design (hardware and software)
* Secure OTA update mechanisms
* Experience in a start-up or high-growth environment
