Senior Mechanical Engineer II

Werfen•Bedford, MA

1d•$130,000 - $160,000

About The Position

The Senior Mechanical Engineer II leads the design, development, and integration of complex electromechanical systems for medical diagnostic and IVD products, including motion systems, precision fluidics, and thermal management solutions. The role applies advanced engineering principles, parametric CAD modeling (Creo preferred), simulation tools, and expertise in GD&T, tolerance analysis, and complex assemblies to deliver robust, manufacturable designs. The engineer translates product requirements into system architecture and mechanical solutions, making design trade-offs that balance performance, cost, manufacturability, and time-to-market while ensuring compliance with medical device quality and regulatory standards. The position has broad ownership across the product development lifecycle, from concept through verification, validation, and design transfer, and collaborates with cross-functional teams to guide technical decisions and product success. The Senior Engineer II brings experience designing for a range of manufacturing processes and large-scale systems, contributes to product architecture decisions informed by customer and marketing inputs, and provides technical leadership by guiding project direction, influencing engineering practices, and mentoring junior engineers. This is an individual-contributor role that may also serve as a core team member or technical lead for a project or product line. It includes authoring design-control documentation, independently planning and prioritizing complex work, evaluating designs and processes, identifying and documenting product defects, supporting CAPA and complaint investigations, and communicating technical information to multidisciplinary teams. Some domestic and international travel may be required. The annual base salary range is $130,000 to $160,000. The role is eligible for medical, dental, and vision insurance, a 401(k) retirement plan with employer match, and paid vacation and sick leave.
