As an Embedded Software Engineer at Lexington Medical, you will contribute to the development, testing, and integration of embedded firmware in the AEONTM surgical stapling platform and the products behind it. You will implement and debug low-level drivers and communication interfaces (SPI, I2C, CAN, UART, USB) as well as the application logic that commands and monitors electromechanical subsystems, then take that firmware to the bench and prove it works against real hardware. You will work day to day with embedded, electrical, mechanical, and systems engineers, particularly during hardware bring-up, when firmware, board, and mechanism all meet for the first time.

Design, implement, and test embedded firmware running on ARM Cortex-M or equivalent microcontroller-based systems in C and C++.

Develop and integrate low-level drivers and communication interfaces, including SPI, I2C, CAN, UART, and USB.

Build and debug the application-layer logic that controls and monitors electromechanical systems, including motor control and sensor feedback.

Work with electrical and mechanical engineers on hardware bring-up, debugging, and system integration, confirming that firmware interacts correctly with motors, sensors, and physical mechanisms.

Debug at the bench using oscilloscopes, logic analyzers, and JTAG or SWD hardware debuggers, and isolate whether a failure is in firmware, hardware, or the mechanism.

Participate in code reviews and design discussions, and apply the modular, maintainable firmware patterns the team uses.

Support verification and validation activities through bench testing and system-level testing.

Document software requirements, design decisions, and test results in alignment with FDA design controls and IEC 62304 expectations.

Contribute to firmware quality, reliability, and traceability as the platform matures.
