- We are seeking a highly capable Senior Mechanical Design Engineer to support the design and development of alkaline electrolyser stacks for large scale industrial hydrogen production systems, with a focus on multi-MW class electrolyser stack as product platform.
- This role will drive the mechanical design of critical stack components and subassemblies from concept development and detailed design through prototyping, testing, validation, scale-up and industrialization.
- The ideal candidate should bring in robust hands-on experience in complex fluid and pressure-bearing assemblies, including stack architecture, compression systems, sealing, manifolding, structural design, thermal management, tolerance stack-up, materials selection, and design for manufacturability.

Key Responsibilities:
- Own the mechanical design and development of multi-MW scale industrial alkaline electrolyser stack, electrolysis cells and related components, subassemblies such as end plates, cell frames, tie-rod or compression systems, elastic elements, manifolds, separators, electrodes, seals & gaskets,



flow distribution features, structural & electrical interfaces.
- Develop 3D CAD models, detailed drawings, GD&T;, tolerance stack-ups, bill of materials, and engineering change documentation for stack and stack subcomponents.
- Own the design of stack hardware to achieve mechanical integrity, uniform compression, leak-tight sealing, uniform flow & temperature distribution, manufacturability, serviceability, and long-term durability under operating conditions.
- Perform engineering analyses including structural analysis, tolerance analysis, thermal considerations, flow distribution assessment, and failure risk evaluation using analytical methods and simulation tools such as FEA and CFD.
- Collaborate closely with electrochemistry, systems engineering, manufacturing, quality, supply chain, and testing teams to ensure stack design meets performance, reliability, cost, and schedule targets.
