Job description

Key Responsibilities

• Head 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, Chemical, or Materials Science background.
• 5 to 10 years of experience in electrolyzer, fuel cell, or similar electrochemical stack systems or EV systems.
• Mechanical integration experience of multi‑layer assemblies.
• Strong understanding of stack compression mechanics, load transfer through layered structures, and torque‑preload relationships in bolted joints.
• Experience with hydraulic press assembly processes, gasket sealing mechanics and material behaviour, and porous transport layer (PTL) compression characteristics.
• Ability to interpret stress‑strain curves, contact mechanics, and nonlinear material behaviour.
