Senior Embedded C Software Engineer
You will join a multidisciplinary engineering team developing embedded software for microcontroller‑based systems used within our magnet technology. The software you create will run directly on the system, helping monitor performance, interact with sensors, manage control functions, log data and support safe, reliable operation.
What You’ll Be Doing
- Designing, developing and maintaining embedded software in C for ARM‑based microcontroller platforms.
- Building reliable firmware for real‑time environments, including RTOS‑based applications.
- Translating requirements into clear, structured software designs, implementation plans and testable outputs.
- Developing low‑level drivers, peripheral interfaces and hardware‑facing software components.
- Integrating software with hardware subsystems including sensors, communication interfaces and control electronics.
- Debugging and resolving software and hardware integration issues using tools such as JTAG/SWD debuggers, oscilloscopes and logic analyzers.
- Creating and supporting unit, integration and system‑level testing to ensure robust performance.
- Producing clear technical documentation and supporting structured development, release and configuration‑control processes.
- Contributing to code reviews, continuous improvement, software quality practices and shared engineering standards.
- Collaborating with electronics, systems, verification, manufacturing, service and product teams to deliver maintainable solutions.
Required Experience and Skills
- Strong experience developing embedded software or firmware in C.
- Practical experience with ARM‑based microcontrollers, ideally Cortex‑M platforms.
- Good working knowledge of real‑time systems and RTOS concepts.
- Experience with embedded interfaces such as UART, SPI, I2C, CAN or USB.
- Confidence debugging embedded systems and solving technical problems methodically.
- Experience using version control tools such as Git or Azure DevOps.
- Ability to work closely with electronics and hardware teams, including reading schematics or supporting board bring‑up.
- Clear communication skills, with the ability to explain technical topics and contribute constructively in design reviews and project discussions.
Helpful (Optional) Experience
- Bootloaders, firmware update mechanisms or secure update processes.
- Safety or regulatory frameworks such as MISRA C, IEC 62304, IEC 61508, ISO 26262, DO‑178C.
- Static analysis, unit test frameworks, automated testing or hardware‑in‑the‑loop testing.
- Python or other scripting tools for test automation or build support.
- CI/CD pipelines for embedded software.
- Communications stacks, diagnostics or fieldbus protocols.
Industry Background
Experience can be gained in a variety of industries. We welcome candidates who have developed embedded software for products involving sensors, control systems, monitoring, data logging or real‑time interaction with hardware. Examples include medical technology, automotive, aerospace, industrial, consumer technology, marine, energy or other regulated or complex engineering environments.
Benefits
