Embedded Electronics Engineer - Matter & Thread Dimming Projects

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
