Job description

Design, develop, and maintain embedded software for IoT devices and edge-connected systems.
Develop low-level embedded software, including device drivers, board support packages (BSPs), and RTOS/kernel components.
Implement and optimise secure IoT communication protocols such as MQTT, BLE, Wi-Fi, Zigbee, and LoRa.
Develop connectivity, telemetry, remote monitoring, and device management functionality.
Build automated test frameworks, perform Hardware-in-the-Loop (HIL) testing, and support prototype validation.
Collaborate closely with hardware, cloud, and product teams to deliver end-to-end IoT solutions.
Troubleshoot embedded hardware/software issues and optimise system performance, reliability, and power consumption.
Maintain technical documentation and contribute to software architecture decisions.
Participate in CI/CD pipelines for automated testing, deployment, and software delivery.

Requirements

Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Electronics Engineering, or a related discipline.
Strong commercial experience developing embedded software in C/C++.

Hands-on experience with microcontrollers such as ARM Cortex-M, STM32, ESP32, or similar platforms.
Strong understanding of IoT architectures, edge devices, and connected product development.
Experience implementing wireless communication protocols including BLE, Wi-Fi, Zigbee, Thread, LoRaWAN, or cellular IoT technologies.
Knowledge of secure communications, device authentication, encryption, and secure data transmission.
Experience with low-power embedded design and battery-powered IoT devices.
Familiarity with automated testing frameworks and debugging tools such as JTAG, GDB, oscilloscopes, and logic analysers.
Experience using Git and CI/CD tools such as Jenkins, GitLab CI, or Azure DevOps.

Desirable Skills

Yocto Linux and embedded Linux customisation.
OTA firmware update systems and device lifecycle management.
Bootloader development and firmware architecture.
Experience with cloud IoT platforms (AWS IoT, Azure IoT, Google Cloud IoT, or similar).
Knowledge of SPI, I2C, UART, CAN, GPIO, and other embedded communication interfaces.
Experience with edge computing and real-time data processing.
TDD/BDD methodologies and hardware simulation/testing environments.
