• Participate in the selection of stack component suppliers: membrane, GDL, bipolar plates and gaskets;
• Participate in fuel cell stack test campaigns by contributing to protocol development, test execution, and data analysis to support design validation and iteration;
• Collaborate with the manufacturing team to ensure correct assembly protocols are followed and with the simulation team to ensure the adequate models and hypotheses are taken;
• Support the company in the development of the technical strategy roadmap regarding fuel cell stacks;
• Support HR on recruitment activities in the fuel cell stack team;
• Support IP development and technical documentation.

Your Profile

• MSc or PhD in Mechanical Engineering, Electrochemistry, Chemical Engineering, Energy Systems, or related fields;
• 5 year experience in designing and developing fuel cell stacks for mobility applications;
• Proven track record in testing and delivering functional fuel cell stacks prototypes;
• Familiarity with CAD, CFD, FEA and multiphysics electrochemical softwares;
• Prior experience in aerospace applications is a strong plus, especially in the context of lightweight design, high-reliability systems, and compliance with aviation standards;
• Experience with systems engineering methodologies (e.g., requirement flow-down, interface definition, functional architecture) is a significant asset;
• Ability to thrive in a fast paced environment bringing innovative solutions;
• Strong team spirit with great communication skills across technical and non technical audiences;
• High level of written and spoken English mandatory. French and other languages would be a bonus.
