Mechanical Engineer

Company Overview:

Lexington Medical, Inc. is a medical device company developing and manufacturing minimally invasive surgical stapling solutions in the Boston area. With the highest standards in design engineering and smart manufacturing, our team delivers disruptive technology to healthcare providers, improving surgical outcomes for patients in a thriving $6B+ surgical stapler market.

Rooted in a talent-dense culture, we are committed to innovation, foster continuous growth, and achieve great heights together. At Lexington Medical, Inc., you will have the opportunity to impact the lives of millions of patients worldwide and thrive in a fast-growing MedTech company.

Role Overview:

We are hiring a Mechanical Engineer to join Lexington Medical's R&D team in Bedford, MA. Ideal for engineers who want broad ownership and exposure to the full product development lifecycle.

Join a hands-on mechanical engineering team developing precision surgical stapling devices across three specialized groups:

• Reloads – Cartridge mechanisms, staple formation/geometry, firing sequences, and tissue compression
• Manual Handle – Linkages, gear trains, force transfer, ergonomics, and DFM for manual handle platforms
• Power Handle – Motorized systems integrating mechatronics, motors, sensors, and electronics

Placement is based on experience and interest. Across all three teams, you will design components and assemblies, build and test prototypes, iterate rapidly, and support design transfer to manufacturing.

Responsibilities:

• Design, prototype, and validate mechanical and mechatronic subsystems for minimally invasive surgical devices.
• Develop 3D CAD models, drawings, and assemblies; review peer designs with a focus on performance, reliability, and manufacturability.
• Select materials and components appropriate for precision, miniaturized mechanisms.
• Execute hands-on testing and experimentation to characterize performance and inform design decisions.
• Partner closely with manufacturing to optimize designs for DFM/DFA and support design transfer.
• Document development activities in accordance with medical device requirements (design history, test reports, technical documentation).
• Contribute to continuous improvement of existing products with a focus on quality, speed, and cost.

Qualifications:

• B.S. in Mechanical Engineering or equivalent.
• Strong mechanical engineering fundamentals and hands-on problem-solving ability.
• Proficiency in 3D CAD (SolidWorks preferred).
• Experience designing precision mechanical components, with exposure to manufacturing processes such as injection molding, CNC machining, additive manufacturing, or stamping.
• Curiosity, ownership mindset, and ability to operate effectively in a fast-paced, collaborative environment.
• Medical device experience is a plus, but not required.

What Success Looks Like In This Role:

• Within the first 3–6 months, you are independently designing and testing components that feed directly into active product programs.
• Within the first year, your designs have shipped to manufacturing and supported procedures in the operating room.
• You are known for strong engineering judgment, bias toward action, and thoughtful collaboration across disciplines.

Portfolio Required: Please submit a portfolio demonstrating relevant engineering projects, including CAD work, prototypes, technical documentation, or other examples of your engineering experience. Academic projects are welcome.

Location & Work Arrangement:

This position is based in Bedford, Massachusetts (near Boston) and is an onsite role.
