Staff Engineer Stack Integration (India)

Job Description: 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. We are seeking a highly skilled Senior Stack Integration Engineer to lead the integration and optimization of electrolyzer stack architectures. This role focuses on ensuring robust mechanical, electrochemical, and pressure-performance integration across stack layers to achieve superior durability, efficiency, and operability. The ideal candidate will have deep expertise in load transfer mechanisms, compression behaviour, and torque-induced sealing performance, along with a strong understanding of electrochemical stack physics.
