Summary
🤩
Rockstar🎓
Top SchoolMatt Hazley is a Principal Firmware Engineer with over a decade of hands-on experience designing and shipping IoT products from prototype to production, currently based in Belfast. He blends low-level embedded C/C++ expertise on ARM and 8-bit MCUs with cloud, mobile, and UX thinking—having led cross-disciplinary teams and acted as product owner to deliver connected devices at Dyson and other companies. A Matter standards contributor and CSA ambassador, he’s applied that work to real products (including fan control in the widely watched connectedhomeip project), bridging standards leadership with practical firmware implementations. Known for pragmatic system design, custom PCB and protocol work, and tooling that accelerates teams, he mentors engineers while still diving into code and hardware when it matters. He’s equally comfortable shaping strategy for smart-home ecosystems and solving subtle edge cases in resource-constrained firmware.
