Responsibilities
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.
- 4+ 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.
