We are looking for a passionate and skilled Firmware Engineer to join our team developing software for Heart-Lung Machines and other safety-critical medical devices. In this role, you will design, implement, and test low-level embedded software for microcontroller-based systems, working closely with hardware and software teams to ensure IEC 62304 Class C compliance. Reporting to the Manager-Firmware Engineering, you will contribute to the delivery of robust and reliable embedded software for life-saving technologies.

• Design, implement, and maintain software for microcontroller-based medical devices, ensuring compliance with safety and regulatory standards.
• Work with RTOS-based systems, focusing on real-time performance, reliability, and efficient resource usage.
• Collaborate with architects, test engineers, and system engineers to define interfaces, hardware abstraction layers, and low-level drivers.
• Participate in code reviews, design reviews, and risk assessments to ensure high code quality and adherence to design constraints.
• Apply unit testing, static code analysis, and other industry best practices for safety-critical software.
• Support integration testing, debugging, and root cause analysis of issues arising in system-level testing (e.g., HIL/SIL)
• Develop and maintain technical documentation, including software design, implementation details, and traceability to requirements.
• Contribute to continuous improvement of development processes, tool chains, and testing frameworks.

• Strong programming skills in C programming, with experience in real-time embedded software development.
• Familiarity with RTOS platforms (e.g., Keil FuSa RTX, FreeRTOS, Zephyr, or similar).
• Experience with low-level hardware interfaces (e.g., SPI, I2C, UART, ADC/DAC, PWM, GPIO).
• Knowledge of software development for safety-critical systems, preferably in compliance with IEC 62304, ISO 13485, and ISO 14971
• Experience with unit testing, static analysis tools (e.g., Polyspace, Vector cast, Cppcheck, PC-lint, Coverity), and code coverage analysis.
• Familiarity with version control (e.g., Git), issue tracking, and CI/CD pipelines for embedded projects.
• Understanding of CAN protocols, digital I/O, and embedded debugging tools (e.g., oscilloscopes, logic analyzers, JTAG/SWD).
• Basic knowledge of hardware schematics and datasheets is a plus.
• Bachelor's or Master's degree in Electronics, Computer Engineering, Embedded Systems, or a related field.
• 3-10 years of experience in embedded software development, preferably in medical or other regulated industries.
• Experience in developing software for microcontrollers (e.g., STM
  32, NXP, Renesas) in a real-time environment.
• Knowledge of regulatory and quality requirements for medical device development is an advantage.

• Occasional travel may be required

• A role within a young and motivated team, with structured training and development programmes.
• A stimulating working environment in the fields of cybersecurity and IT, with opportunities to develop your skills on complex projects.
• Annual salary commensurate with experience
