Job Description:
Key Responsibilities
Design and develop mechanical components for PEM Electrolyzer stacks, including bipolar/end plates, gaskets and seals, current collectors, tie-rod/tension assemblies, and manifolding, using SolidWorks or equivalent CAD tools.
Create and maintain detailed part and assembly drawings with GD&T;, tolerance dimensioning, and third-angle projection per ASME standards.
Perform engineering analysis such as tolerance stack-up, structural/stiffness calculations for endplates, sealing calculations for gaskets, flow field analysis like pressure drop calculations for Bipolar Plates, and material compatibility assessments
Lead or contribute to DFMEA studies for design changes (e.g., materials, coatings, surface finishes), identifying failure modes, causes, and effects, and defining mitigations.
Develop and validate stack assembly processes, including uniform torquing/compression strategies, torque sequencing, and pressure distribution verification
Author and maintain detailed component specifications for stack mechanical components (bipolar/end plates,



gaskets/seals, current collectors, tie-rods), including dimensional, material, and performance requirements.
Collaborate with supply chain and quality teams to validate that specifications are achievable at the intended production volume, and refine specs based on DFM/DFA feedback.
Collaborate with manufacturing and quality teams to define assembly work instructions, inspection & acceptance criteria, and fixture/tooling requirements.
Support root-cause investigations for field & test failures and translate findings into design improvements.
Prepare and maintain engineering documentation: design reports, drawings, BOMs, ECNs, and DFMEA records.
Work closely with R&D;, test engineering, and supply chain to bring current designs from concept through pilot to production scale.
