Principal Embedded Software Engineer

<p>Lexington Medical, Inc. is hiring a Principal&nbsp;Embedded&nbsp;Software Engineer in Bedford, MA to develop&nbsp;embedded&nbsp;software for surgical stapling devices. You will build and own&nbsp;embedded&nbsp;software controlling a complex electromechanical surgical stapling system, while setting the architecture and technical standards that guide the platform longer term.&nbsp;</p>

<p><strong>About Lexington Medical</strong>&nbsp;</p>

<p>Lexington Medical, Inc. is a medical device company designing and&nbsp;manufacturing surgical stapling technology at our headquarters in Bedford, Massachusetts, just outside Boston. Our AEON™&nbsp;Endostapler&nbsp;is an FDA-cleared, minimally invasive surgical stapler used in operating rooms around the world. With engineering,&nbsp;manufacturing, and quality working closely together, engineers stay close to the product and see their work move from an idea through prototyping, testing,&nbsp;manufacturing, and&nbsp;ultimately into&nbsp;the operating room.&nbsp;</p>

<p><strong>About the Role</strong>&nbsp;</p>

<p>As a Principal&nbsp;Embedded&nbsp;Software Engineer at Lexington Medical, you will own&nbsp;embedded&nbsp;software architecture while&nbsp;remaining&nbsp;an active individual contributor. You will write production code, integrate drivers, debug at the hardware level, and work&nbsp;at&nbsp;the bench alongside electrical and mechanical engineers.&nbsp;</p>

<p>The software&nbsp;operates&nbsp;under tight real-time and safety-critical constraints and directly controls electromechanical actuation and sensing. You will help solve the problems that appear where software meets actual hardware, while also&nbsp;establishing&nbsp;the technical direction, development practices, and software quality standards for the platform.&nbsp;</p>

<p>This role is designed for a principal-level engineer who wants the scope and influence of a technical leader without moving away from engineering itself.&nbsp;</p>

<p><strong>Responsibilities</strong>&nbsp;</p>

<ul>

<li>Design, build, and integrate real-time&nbsp;embedded&nbsp;software for Lexington Medical's surgical stapling platform and supporting devices, primarily using ARM Cortex-M or equivalent microcontroller-based systems. </li>

<li>Define and evolve the embedded&nbsp;software architecture, including major structural decisions, technical tradeoffs, and longer-term platform direction. </li>

<li>Write production&nbsp;C and C++ code as an active contributor to core&nbsp;embedded&nbsp;systems. </li>

<li>Develop and debug low-level drivers, communication interfaces including SPI, I2C, CAN, UART, and USB, and application-layer logic controlling electromechanical actuation and sensing. </li>

<li>Use oscilloscopes, logic analyzers, JTAG/SWD, and other debugging tools to solve hardware/software integration problems at&nbsp;the bench. </li>

<li>Own the structure, standards, dependencies, and long-term health of the embedded&nbsp;software codebase. </li>

<li>Establish documentation, risk-management, and verification practices aligned with IEC 62304 and&nbsp;applicable&nbsp;FDA medical device requirements. </li>

<li>Lead code and design reviews, mentor other engineers, and help establish&nbsp;a high technical bar across the&nbsp;embedded&nbsp;team. </li>
