Senior Embedded Software Engineer - (Linux, Yocto, Buildroot)

Join a pioneering team building the next generation of space-powered IoT solutions. My client are developing a highly advanced satellite network that connects billions of devices worldwide - enabling users to sense, track, and act on data anywhere on the planet.

As a Senior Embedded Software Engineer, you’ll design and optimize software for low-power, battery-operated IoT devices that communicate through space-based systems. You’ll focus on performance, power efficiency, system reliability, and automated testing frameworks.

Key Responsibilities

Embedded Development

• Design, implement, and maintain low-level software including BSPs and device drivers.


• Optimize firmware for minimal power consumption and reliable real-time performance.


• Customize and tune RTOS (e.g., FreeRTOS) or embedded Linux kernels.


• Integrate secure and efficient IoT communication protocols (e.g., MQTT, BLE).

Testing & Automation

• Develop automated unit, integration, and regression test frameworks.


• Conduct prototype and hardware-in-the-loop (HIL) testing for validation.
  
• Implement CI/CD pipelines using tools such as Jenkins, GitLab CI, or Azure DevOps.


• Use oscilloscopes, logic and protocol analyzers, and other debugging tools to test embedded systems.


• Work closely with hardware engineers to ensure seamless software-hardware integration.


• Maintain detailed documentation for development, testing, and validation processes.

Skills & Experience

• Strong programming skills in C, C++, and Python (Shell/Bash scripting a plus).


• Proven experience with ARM Cortex, ESP32, or STM32 microcontroller platforms.


• Experience with Yocto or similar build systems.


• Understanding of wireless communication (Wi-Fi, Bluetooth, Zigbee, LoRa).


• Knowledge of SPI, I2C, UART, and GPIO interfaces.


• Experience with OTA firmware updates and secure bootloaders.


• Familiarity with hardware simulation and mock testing environments.


• Exposure to TDD/BDD methodologies.

Qualifications

• Bachelor’s or Master’s in Computer Science, Electrical Engineering, or related field.


• Eligible to work in the UK (no visa sponsorship available).

Why Join

• Be part of a mission to expand global connectivity and make space technology more sustainable.


• Work in a culture that values innovation, curiosity, and collaboration.


• Competitive compensation, professional development, and wellness benefits.
