## Description

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.

Connectivity & Networking ------------------------

- 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.

Device Security & OTA Management ---------------------------------

- 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.

Edge & Cloud Integration -------------------------

- 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.

Compliance & Testing ---------------------

- 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.

Cross-Functional Collaboration ------------------------------

- 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.

Requirements ------------

- Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent practical experience.

- 5+ years of experience building connected embedded products, or strong relevant industry/project experience.

- Good proficiency in C/C++ for embedded systems, with experience working with RTOS environments such as Zephyr or FreeRTOS.

- Experience with Python for testing, tooling, or automation.

- Solid understanding of device connectivity and networking fundamentals, including IP networking and common transport/application protocols.

- Experience implementing or supporting secure device communications using TLS, certificates, or device provisioning workflows.

- Familiarity with firmware update systems, bootloaders, or CI/CD workflows for embedded software.

- Practical debugging experience using lab and software tools such as logic analysers, protocol analysers, network sniffers, or observability platforms.

- Strong problem-solving skills and the ability to work across hardware and software boundaries.

Nice to Have -------------

- Experience with low-power wireless technologies such as Thread, Zigbee, or BLE.

- Familiarity with cloud IoT services on AWS, Azure, or GCP.

- Exposure to secure boot, TPMs, secure elements, or hardware attestation.

- Experience with EMC/RF testing, antenna bring-up, or factory test processes.

- Awareness of relevant cybersecurity or privacy standards such as IEC 62443, ETSI EN 303 645, ISO 27001, or GDPR.

- Experience working on industrial, energy, or other distributed device deployments.

Benefits --------

- Competitive salary and an equity sign-on bonus

- Biannual bonus scheme

- Fully expensed tech to match your needs

- Paid annual leave

- Breakfast and dinner allowance for office-based employees
