Desirable

• We’re looking for a Senior IoT Engineer to help design, build, and scale the connected hardware powering the Energy Network
• This is a hands-on role spanning embedded systems, networking, device security, and fleet connectivity — from prototype through to deployment
• You’ll contribute to building resilient connectivity, secure provisioning, and robust telemetry across a growing fleet of distributed energy devices
• You’ll play an important role in shaping how our devices connect, communicate, and evolve securely at scale, working closely with firmware, hardware, and backend teams to deliver production-ready systems
• Develop and maintain connectivity across Ethernet, Wi-Fi, Thread, Zigbee, and BLE
• Build and optimise secure, reliable device messaging using protocols such as MQTT, CoAP, HTTP, or WebSockets
• Support reliable device time synchronisation using NTP or PTP
• Contribute to secure boot flows, key and certificate provisioning, and hardware-backed device identity using TPMs or secure elements
• Help build and maintain signed firmware update pipelines, including OTA update and rollback mechanisms
• Support security best practices across the device lifecycle, including vulnerability management and secure provisioning
• Integrate devices with cloud IoT platforms and backend services
• Define and improve telemetry, health monitoring, and observability for deployed devices
• Support reliable operation of connected devices in the field, including debugging fleet issues and improving resilience
• Support testing and validation for safety, EMC, radio, and related product requirements
• Help prepare test plans, certification artefacts, and validation documentation
• Work with manufacturing and cross-functional teams through engineering and production validation cycles
• Work closely with firmware, hardware, power electronics, mechanical, and software teams to deliver production-ready devices
• Contribute to design reviews, technical documentation, and interface specifications
• Share knowledge and contribute to engineering best practices across connectivity, embedded systems, and device security
