Mechanical Engineer II (Stack Engineering)
Status: Exempt (Salaried)
Department: Stack Engineering – 389
Location : Rochester, NY
Position Summary
In this exciting and creative role, you will be responsible for the design of custom fuel cell stack components and incorporation into higher level assemblies (both existing and new product configurations). Using engineering fundamentals, tools, and techniques, you will be responsible for the detailed design of various fuel cell components to meet cost, manufacturability, performance, and reliability requirements. The ideal candidate must be able to create and maintain large 3D CAD assembly models, individual part models/drawings, and associated bills of materials. As part of a cross functional team, you will plan out and conduct hands on prototype builds and testing to validate design functionality and feasibility for production release. The candidate should be creative, self-motivated, detail oriented, and able to handle multiple project assignments within a fast-paced engineering organization including ability to resolve quality and manufacturing related stack issues. This role is to be based out of Plug Power’s Rochester Innovation Center.
