Mechanical Engineer

Lexington Medical, Inc. is hiring a Mechanical Engineer in Bedford, MA to design medical device mechanisms for our AEON™ surgical stapling platform. As a Mechanical Engineer at Lexington Medical, you will take designs from concept to production, with broad ownership of the work along the way.

About Lexington Medical

Lexington Medical, Inc. is a medical device company designing and manufacturing surgical stapling technology at our headquarters in Bedford, Massachusetts, just outside Boston. Our AEON™ Endostapler 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.

About the Role

As a Mechanical Engineer at Lexington Medical, you will join an R&D team developing precision surgical stapling devices across one of three areas. Placement is based on your experience and interests. Across the teams, you will design components and assemblies, build and test prototypes, iterate, and work with manufacturing to bring it into production.

This is a good fit for an engineer who wants to do more than own a narrow piece of a larger program. You will stay close to the physical product and the full development process across three specialized groups:

Reloads: Cartridge mechanisms, staple formation and geometry, firing sequences, and tissue compression.

Manual Handle: Linkages, gear trains, force transfer, ergonomics, and design for manufacturing.

Power Handle: Motorized systems integrating mechanical components, motors, sensors, electronics, and other electromechanical elements.

Responsibilities

• Design, prototype, and validate mechanical and mechatronic subsystems for the AEON™ surgical stapling platform.
• Develop 3D CAD models, engineering drawings, and assemblies using SolidWorks.
• Review designs for mechanical performance, reliability, manufacturability, and appropriate tolerancing.
• Select materials and components for precision, miniaturized mechanical systems.
• Build and test prototypes and use experimental results to guide design decisions.
• Partner with manufacturing engineers on DFM/DFA, process development, and design transfer.
• Document development work in accordance with medical device design controls and quality requirements.
• Support improvements to existing products with a focus on performance, quality, manufacturability, speed, and cost.

Qualifications

• Bachelor's degree in Mechanical Engineering or equivalent.
• Strong mechanical engineering fundamentals and hands-on problem-solving ability.
• Proficiency with 3D CAD; SolidWorks experience is preferred.
• Experience designing precision mechanical components and assemblies.
• Exposure to manufacturing processes such as injection molding, CNC machining, additive manufacturing, or stamping.
• Experience taking designs through prototyping and testing.
• Ability to communicate design decisions clearly and work closely with engineers across disciplines.
• Curiosity, sound engineering judgment, and a strong sense of ownership.
• Medical device or other regulated product-development experience is a plus.

What Success Looks Like

• Within your first 3 to 6 months, you are independently designing and testing components that contribute directly to active product programs.
• Within your first year, you have taken designs through development and into manufacturing.
• Your work reflects strong mechanical judgment, thoughtful experimentation, and attention to the details that determine whether a design performs.

Portfolio

Please submit a portfolio showing relevant engineering work, such as CAD, prototypes, technical drawings, testing, or other examples of how you approach engineering problems. Academic projects are welcome.
