Principal Embedded Software Engineer

Responsibilities

• Personally design, build, and integrate real-time embedded software for Lexington's surgical stapling platform and supporting devices, primarily on ARM Cortex-M or equivalent microcontroller-based systems.
• Hands-on ownership of code, not just architecture review.
• Lead software architecture discussions and decisions, driving consensus across engineering on structure, trade-offs, and long-term direction for the embedded platform.
• Own and manage the embedded software codebase, structure, standards, dependencies, and long-term health, as the engineer accountable for its integrity.
• Lead code reviews across the team, setting the bar for code quality, style, and best practices, and using reviews as a hands-on mentoring tool.
• Write production code on a day-to-day basis as an active, hands-on contributor to core embedded systems, not solely in an oversight capacity.
• Write, integrate, and debug low-level drivers, communication interfaces such as SPI, I2C, CAN, UART, and USB, and application-layer logic that directly controls electromechanical actuation and sensing, working at the bench with hardware, not only in the codebase.
• Set embedded software technical standards, establish documentation and verification processes in alignment with IEC 62304 and FDA Class II/III medical device requirements, and apply them in your own day-to-day engineering work.
• Work side-by-side with electrical and mechanical engineers on the physical hardware to solve real-time integration problems, troubleshoot electromechanical failure modes, and validate system behavior on the bench and in test rigs.
• Provide technical leadership and mentorship to senior and staff-level engineers through design reviews and hands-on pairing on hard technical problems, while partnering with management on hiring and skill development.
• Own technical deliverables and risk mitigation for embedded software projects end to end, from architecture through bring-up, debug, and verification on physical hardware, to supporting the product through its entire lifecycle post-launch.

Qualifications

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Software Engineering, or related discipline.
• 12+ years of embedded software development experience, with substantial hands-on work building embedded systems for electromechanical products, preferably in regulated or safety-critical industries.
• Expert-level proficiency in C and C++ for embedded systems, with additional experience in Python or C# considered a plus.
• Deep, hands-on experience with RTOS-based systems, embedded development workflows, and hardware-level debugging tools (oscilloscopes, logic analyzers, JTAG/SWD).
• Direct, bench-level experience integrating software with complex electromechanical systems — not just theoretical hardware/software boundary knowledge.
• Proven track record leading and mentoring engineers while remaining an active hands-on contributor.
• Deep understanding of software quality systems, documentation control, and risk management.
• Working knowledge of version control and issue tracking tools such as Git and JIRA.
