Principal Embedded Software Engineer

The role

You will build and own embedded software controlling a complex electromechanical surgical stapling system. You will set the architecture and technical standards for the platform while remaining an active individual contributor.

What you will do

• Design, build, and integrate real-time embedded software for the surgical stapling platform.
• Define and evolve the embedded software architecture and technical tradeoffs.
• Write production C and C++ code.
• Develop and debug low-level drivers and communication interfaces.
• Use oscilloscopes, logic analyzers, and JTAG/SWD to solve hardware/software integration problems.
• Own the structure, standards, and long-term health of the codebase.
• Establish documentation, risk management, and verification practices aligned with IEC 62304 and FDA requirements.
• Lead code and design reviews and mentor other engineers.
• Own embedded software technical deliverables and risk mitigation.

Required qualifications

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Software Engineering, or a related discipline.
• 12+ years of embedded software development experience.
• Expert-level proficiency in C and C++ for embedded systems.
• Deep experience with RTOS-based systems and embedded development workflows.
• Experience developing for ARM Cortex-M or comparable microcontroller platforms.
• Strong hardware-level debugging skills using tools such as oscilloscopes, logic analyzers, and JTAG/SWD.
• Direct experience integrating embedded software with complex electromechanical hardware.
• Experience leading technical architecture and mentoring experienced engineers.
• Strong understanding of software quality systems, documentation control, risk management, and IEC 62304 or comparable regulated software-development requirements.
• Working knowledge of Git, JIRA, or similar version-control and issue-tracking systems.

Nice to have

• Experience in a regulated or safety-critical industry.
• Experience with Python or C# is a plus.
