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.

If you want to build intelligent sensing platforms from the ground up — and see your work deployed in the real world — KO2 would love to speak with you.
