About the role We are seeking an experienced embedded software engineer to help develop, maintain, verify, and document the software running on a medical device. The contractor will work on the device's Linux-based console control firmware, collaborating with hardware, FPGA, systems, quality, and regulatory stakeholders. Responsibilities Implement and maintain embedded C and C++ features across drivers, managers, state-machine logic, data collection, and signal-processing components. Diagnose defects using source inspection, logs, target-device behavior, hardware interfaces, and reproducible test cases. Design changes that preserve deterministic behavior, timing requirements, error handling, and safe device responses. Develop unit, integration, hardware-in-the-loop, and regression tests appropriate to the change and available test infrastructure. Follow all applicable quality-system procedures. Required qualifications Demonstrated professional experience developing production embedded software in C and C++ for medical devices. Strong knowledge of C++11 or later, including memory ownership, low-level data handling, interfaces, and debugging. Experience with Linux-based embedded systems, cross-compilation, shell tools, and build systems such as Make. Experience debugging concurrent systems using threads, mutexes, queues, timers, and synchronization primitives. Preferred qualifications Experience with Yocto/OpenEmbedded, cross-toolchains, Docker/Podman, Jenkins, and Linux target deployment. Experience developing software for medical devices, laboratory instruments, cardiovascular systems, imaging, energy delivery, or other safety-critical products.
