Job Description:

• 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 Y14.5 or ISO 2768/1101 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 new designs from concept through pilot to production scale.

Required Qualifications

• Bachelor’s degree in mechanical engineering or a related discipline (master’s degree a plus).
• 2-5 years of hands-on experience mechanical design, product development & engineering execution across product lifecycle ideally in Electrolyzers, fuel cells, batteries, pressure vessels, heat exchangers, or other precision electromechanical assemblies.
• Strong proficiency in 3D CAD (SolidWorks preferred) and 2D drawing creation for Sheetmetals & Machined components with proper GD&T and tolerancing practices.
• Practical experience with DFMEA methodology and root-cause/failure analysis (e.g., 8D).
• Hands on experience with sheetmetal, plastic part & machined component design, and manufacturing processes such as Injection moulding, casting, machining, and fabrication.
• Ability to develop mechanical designs, perform engineering calculations, create technical drawings, and execute design verification activities.
• Strong communication & problem-solving skills, with experience producing clear engineering documentation.
