Embedded Software Engineer

Senior Embedded Software Engineer

Stroud, Gloucestershire | Up to £70,000

KO2’s client is a well-funded, fast-growing tech start-up building intelligent, ultra-low-power sensing systems for real-world environments. Their platforms combine embedded firmware, signal processing, secure wireless connectivity, and edge ML.

They need a Senior Embedded Software Engineer to take ownership from concept to production.

What You’ll Do

* Architect and develop low-power embedded firmware (C/C++)

* Design battery-powered, remote sensing systems

* Build sensor acquisition & real-time signal processing pipelines (MEMS mics, accelerometers, environmental sensors)

* Develop RF systems (LoRa / LPWAN, mesh networking)

* Implement secure communications (encryption, authentication, secure boot, OTA)

* Deploy optimised ML models for on-device acoustic detection

You’ll work closely with hardware, data and product teams to deliver secure, robust, production-ready systems.

What You’ll Bring

* Strong embedded C/C++ expertise

* Full product lifecycle experience (concept → production)

* Proven low-power design experience

* Sensor integration & real-time processing

* RF experience (LoRa or similar)

* Mesh networking & embedded security

* Strong debugging and hardware bring-up skills

Bonus: Acoustic ML, MEMS microphone systems, noise mitigation, start-up experience.
