You'll contribute to building resilient connectivity, secure provisioning, and robust telemetry across a growing fleet of distributed energy devices.

As an IoT Engineer, 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.

Responsibilities:

• 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.
