About the role

<p><span data-contrast="auto">As a Senior Mechanical Engineer at Lexington Medical, you will design AEON surgical stapling instruments in Bedford, MA while mentoring a team engineers. You will stay hands-on in mechanism design, guide mechanical and product engineers through real projects, and own the work from first requirements to updating the Design History File.  The mentoring role is designed to grow into managing the team directly.</span><span data-ccp-props="{}"> </span></p>

<p><strong><span data-contrast="auto">About Lexington Medical</span></strong><span data-ccp-props="{}"> </span></p>

<p><span data-contrast="auto">Lexington Medical is a medical device company designing and manufacturing surgical stapling technology at our headquarters in Bedford, Massachusetts, just outside Boston. Our AEON Endoscopic Stapler is an FDA-cleared, minimally invasive surgical stapler used in operating rooms around the world. With engineering, manufacturing, and quality working closely together, engineers stay close to the product and see their work move from an idea through prototyping, testing, manufacturing, and ultimately into the operating room.</span><span data-ccp-props="{}"> </span></p>

<p><strong><span data-contrast="auto">About the Role</span></strong><span data-ccp-props="{}"> </span></p>

<p><span data-contrast="auto">As a Senior Mechanical Engineer at Lexington Medical, you will be a senior technical voice and mentor for mechanical and product engineers working on our AEON surgical stapling instruments. You will carry products through the full development lifecycle: new product development, design for manufacturability and other DFX improvements, transfer to production, and sustaining changes after launch. You will own meaningful design work yourself, from CAD and tolerance analysis through prototyping and bench testing, while helping the engineers around you sharpen their technical skills.</span><span data-ccp-props="{}"> </span></p>

<p><span data-contrast="auto">This role has a deliberate path into people management. You will start by mentoring the group, reviewing their designs, and coaching them through their projects. Because R&D, manufacturing, quality, regulatory, and supply chain all work in the same Bedford building, you will partner with those teams directly and see the results of your decisions on the production floor.</span><span data-ccp-props="{}"> </span></p>
