Contract Embedded Software Engineer

We are seeking an experienced and self‑driven Consultant Embedded Software Engineer to contribute critical, low‑level expertise to our next‑generation embedded products. This is a hands‑on, mission‑critical contract role focused on the core foundation of our systems: RTOS adaptation, Hardware Abstraction Layers (HAL), and robust driver development. As a contractor, you will be expected to rapidly integrate with our engineering team, take ownership of key technical work packages, and deliver high‑quality, fully tested code within agreed‑upon timelines. RTOS Integration: Independently manage and execute the porting, configuration, and adaptation of Real‑Time Operating Systems (e.g., FreeRTOS, Zephyr) to novel, bare‑metal microcontroller/microprocessor platforms. Low‑Level Driver Development: Architect, develop, and meticulously test device drivers and HAL components (e.g., I2C, SPI, UART, ADC) to ensure reliable interaction with on‑board and external peripherals. Vendor SDK Utilisation: Integrate and leverage established HAL SDKs from leading manufacturers (e.g., STM32Cube, NXP MCUXpresso) to accelerate development and ensure platform compatibility. Hardware‑Software Integration: Collaborate closely with the hardware team to bring‑up new boards, troubleshoot complex hardware‑software interaction issues, and read/interpret schematics and component datasheets. Connectivity Implementation: Design and implement robust embedded software for communication protocols (e.g., Wi‑Fi, BLE, cellular), ensuring reliable and efficient data transfer. Security Contribution: Implement foundational embedded security features such as secure boot components, cryptographic routines, and secure communication layers. Quality & Documentation: Adhere to high coding standards, perform thorough unit testing, participate in code reviews, and provide clear, concise technical documentation for all delivered work packages. Professional Experience: 5+ years of demonstrated, hands‑on professional experience in embedded software development. Programming Mastery: Expert proficiency in Embedded C/C++ with a focus on resource‑constrained environments. RTOS Expertise: In‑depth knowledge of RTOS principles, concurrency, and practical experience with porting/developing applications on at least one major RTOS (e.g., FreeRTOS, Zephyr). Microcontroller Architecture: Strong understanding of 32‑bit microcontroller/microprocessor architectures (e.g., ARM Cortex‑M, Risc‑V). Hardware Interfacing: Proven ability to develop, debug, and optimise low‑level drivers for standard interfaces (SPI, I2C, UART, ADC, DAC, GPIO). Tool Proficiency: Expertise with debugging tools (JTAG/SWD, Logic Analyzers, Oscilloscopes) and version control systems (Git). Autonomy & Delivery: Proven ability to work autonomously, manage work packages, and deliver high‑quality results within fixed contract deadlines. Communication: Excellent written and verbal communication skills for technical documentation and cross‑functional team collaboration. Highly Desirable (Bonus) Skills Experience with safety‑critical or high‑integrity coding standards (e.g., MISRA C). Experience with embedded Linux, kernel modules, or Yocto/Buildroot. Familiarity with IoT communication protocols (e.g., MQTT, CoAP). Experience with automated unit testing and Continuous Integration (CI) for embedded systems.
