Job Description
Role Purpose
You will design, develop and industrialise Matter-certified dimming products using Thread for smart lighting applications. This cross-disciplinary role spans hardware, embedded firmware and system integration with a strong focus on interoperability, regulatory compliance and exceptional dimming performance.
Your work will ensure products are ready for volume production, certified to industry standards, and deliver high-quality, flicker-free behaviour across a wide range of loads.
Key Responsibilities
Product & System Design
* Lead design of smart dimming products (leading/ trailing edge, 0–10V, DALI, PWM).
* Define system architecture including MCU, RF, mains power electronics, sensing and protection circuitry.
* Ensure robust dimming performance: flicker-free, low noise, wide load compatibility.
Hardware Engineering
* Create and review schematics and PCB layouts for low-power RF and mains-rated circuits.
* Evaluate and select Thread-capable SoCs (e.g., Nordic, Silicon Labs, NXP, Espressif).
* Design for EMC, ESD, thermal performance and manufacturability.
* Support prototype build-ups, bring-up and debugging.
Firmware & Connectivity
* Develop or integrate embedded firmware for Matter and Thread stacks.
* Implement relevant Zigbee/Thread device clusters for lighting control.
* Support OTA updates, commissioning and diagnostics.
* Interface with mobile apps and cloud / ecosystem partners (Apple, Google, Amazon).
Compliance & Certification
* Lead/support Matter and Thread certification activity.
* Drive compliance with UKCA, CE, LVD, EMC, RED, and RoHS.
* Manage engagement with test houses and certification bodies.
Manufacturing & Lifecycle Support
* Collaborate with contract manufacturers during NPI and mass production phases.
* Generate and maintain technical documentation (schematics, test specifications, production test plans).
* Investigate field issues and support continuous improvement efforts.
Required Skills & Experience
Essential
* Demonstrable experience designing embedded/electronics products for volume production.
* Strong understanding of Matter and Thread or closely related networks (e.g., Zigbee).
* Experience with dimming and lighting control electronics.
* Knowledge of mains-powered product design and safety requirements.
* Familiarity with UK/EU regulatory compliance and certification processes.
Desirable
* Hands-on experience achieving Matter certification.
* Exposure to smart lighting ecosystems (Apple Home, Google Home, Alexa).
* Knowledge of DALI, KNX or professional lighting control systems.
* Experience with design optimization and cost engineering for high-volume manufacture.
Qualifications
* Degree or equivalent in Electronics Engineering, Embedded Systems or a related discipline.
Personal Attributes
* Structured and analytical problem solver.
* Clear communicator and team player.
* Pragmatic yet quality-focused engineer who is looking for a growth opportunity.
