Full Job Description
Fourier is on a mission to make on-site hydrogen universally accessible. Our breakthrough architecture delivers highly modular, fully automated electrolyzer systems that scale to any capacity and optimize efficiency across all load profiles. We are building the infrastructure necessary for a purely sustainable, emission-free global energy future — and we need exceptional engineers to help us get there. ABOUT THE ROLE We are seeking a Senior Mechanical Engineer with deep hands-on expertise to lead mechanical design, analysis, integration, and validation of our commercial hydrogen production systems. This is a high-ownership role spanning all subunits and design aspects and the full balance-of-plant envelope that ties them together. This role sits at the intersection of mechanical, electrical, and manufacturing disciplines. You will co-own DFM/DFA strategy with our manufacturing partners and serve as the primary mechanical interface to our electrical and electronics engineering teams — ensuring that both high-voltage (HV) power conversion systems and low-voltage (LV) control and sensing electronics are packaged safely, thermally managed, and fully integrated into production enclosures. ROLES AND RESPONSIBILITIES - Lead concept development, design trades, and down-select decisions for all mechanical subsystems from water purification through post-production H₂ purification - Own 3D CAD design of complex parts and assemblies using SolidWorks or equivalent — including sheet metal, plastics, insulation systems, sealing methods, connectors, and fasteners - Review and develop process flow diagrams, P&IDs, and mechanical design documentation - Perform first-principles hand calculations for sizing and performance of fluid, thermal, and structural systems - Collaborate closely with the electrical and electronics engineering teams to integrate high-voltage (HV) power electronics and low-voltage (LV) control, sensing, and communications systems into mechanical enclosures - Desig
