Staff Engineer – Stack Integration

**Key Responsibilities** * Lead the integration of multi-layer electrolyzer stack components (MEA, PTL, gaskets, bipolar plates) to ensure proper fit, function, and performance. * Define and optimize stack compression strategy, including compression windows, tolerances, and assembly sequences. * Analyse and control load transfer mechanisms across layers under hydraulic pressing and bolt torquing conditions. * Ensure uniform contact pressure distribution to balance sealing integrity, electrical contact resistance, and component durability. * Evaluate mechanical behaviour of layers (elastic/plastic deformation, creep, stress relaxation) under assembly and operating conditions. * Improve pressure handling capability of the stack, including resistance to leakage, deformation, and mechanical failure. * Correlate mechanical compression with electrochemical performance (efficiency, voltage losses, degradation). * Develop and use FEA models to predict stress, strain, and contact pressure distribution across the stack. * Design and execute validation tests (compression mapping, torque-tension, leak and pressure cycling tests). * Collaborate cross-functionally to ensure design robustness, manufacturability, and scalability of stack integration solutions. **Required Qualifications** * B.E or M.E in Mechanical or Chemical or Material science background * 5 to 10 years of experience required in Electrolyzer, fuel cell, or similar electrochemical stack systems or EV systems * Mechanical integration of multi-layer assemblies. * Strong understanding of: * Stack compression mechanics * Load transfer through layered structures * Torque-preload relationships in bolted joints * Experience with: * Hydraulic press assembly processes * Gasket sealing mechanics and material behaviour * Porous transport layer (PTL) compression characteristics * Ability to interpret: * Stress-strain curves * Contact mechanics * Nonlinear material behaviour. **Skills:-** Electrochemical Engineering, Fuel Cells, Hydraulic Systems, Integration, Pressure Management **Education: -** Bachelor of Engineering / Bachelor of Technology (B.E./B.Tech) - Chemical Engineering, Bachelor of Engineering / Bachelor of Technology (B.E./B.Tech) - Materials Science, Bachelor of Engineering / Bachelor of Technology (B.E./B.Tech) - Mechanical Engineering _Ohmium is an equal opportunity employer.
