Embedded / Electronics Engineer – Matter & Thread Dimming Products
Location
UK Wiltshire HQ based
Occasional travel to UK or EU manufacturing / test sites may be required.
Role Purpose
To design, develop and industrialise Matter-certified, Thread-based dimming products for smart lighting applications, from concept through to production. The role spans hardware, firmware and system integration, with a strong focus on regulatory compliance, interoperability and high-quality dimming performance.
Key Responsibilities
Product & System Design
* Design smart dimming products (leading-edge, trailing-edge, 0–10V, DALI or PWM as applicable) compliant with Matter over Thread
* Define system architecture covering MCU, RF, power electronics, sensing and protection
* Ensure excellent dimming performance (flicker-free, low-noise, wide load compatibility)
Hardware Engineering
* Schematic design and PCB layout oversight for low-power RF and mains-rated electronics
* Selection of Thread-capable SoCs (e.g. Nordic, Silicon Labs, NXP, Espressif)
* Design for EMC, ESD, thermal performance and manufacturability
* Support prototype builds, bring-up and debugging
Firmware & Connectivity
* Develop or integrate embedded firmware for Matter and Thread stacks
* Implement device clusters relevant to lighting and dimming
* Support OTA updates, commissioning and diagnostics
* Work with mobile apps and ecosystem partners (Apple, Google, Amazon)
Compliance & Certification
* Lead or support Matter certification and Thread certification
* Ensure compliance with UK/EU regulations (UKCA, CE, LVD, EMC, RED, RoHS)
* Work with test houses and certification bodies
Manufacturing & Lifecycle Support
* Collaborate with contract manufacturers to support NPI and mass production
* Create technical documentation (schematics, test specs, production test procedures)
* Support field issues, root-cause analysis and continuous improvement
Required Skills & Experience
Essential
* Proven experience designing embedded or electronics products for volume manufacture
* Strong understanding of Matter and Thread (or closely related IoT protocols such as Zigbee)
* Experience with dimming or lighting control electronics
* Knowledge of mains-powered product design and safety considerations
* Familiarity with UK/EU regulatory requirements
Desirable
* Hands-on experience taking a Matter product through certification
* Experience with smart lighting ecosystems (Apple Home, Google Home, Alexa)
* Knowledge of DALI, KNX or professional lighting control systems
* Experience in cost-down and design optimisation for high-volume products
Qualifications
* Degree (or equivalent experience) in Electronics Engineering, Embedded Systems or a related discipline
Personal Attributes
* Structured, detail-oriented problem solver
