Senior Mechanical Engineer

Fourier is working on making on-site Hydrogen universally accessible. Our breakthrough architecture enables highly modular and fully automated electrolyzers that scale to any size and optimize efficiency at all loads. We are on a mission to transition the global energy landscape towards a purely sustainable and emission-free future. About the Role We are looking for a Senior Mechanical Engineer to aid in the design, assembly, testing, and optimization of our system. The Fourier hardware platform integrates complex systems, including low to medium-pressure water and gas piping, medium-voltage high-power electronics, and hydrogen gas production and processing in outdoor environments. We're looking for a Senior Mechanical Engineer with a strong background in designing robust, safety-critical hardware systems. Fourier engineers work in a hands-on, collaborative environment to solve problems and advance progress. Qualified candidates should have prior hands-on experience in a mechanical lab or an industrial company. Roles and responsibilities Complete lifecycle ownership (concept & detailed design, prototyping, assembly, deployment & support) of major components and assemblies within the Fourier product line Create and maintain supporting documentation for your systems, including engineering drawings and Bill of Materials Assess failure modes that involve thermal/structural/electrical/chemical/fluid interactions Problem-solving and risk mitigation Oversee the assembly and setup of benchtop test rigs, prototypes, and production units Qualifications Required: B.S. in Mechanical Engineering or equivalent 4+ years of relevant experience Hands-on experience assembling mechanical and piping systems Experience designing and building structures, from 3D CAD and/or 2D drawings through fabrication and assembly Experience designing and developing cost-optimized solutions Comfortable performing hand calculations Preferred: Advanced degree (M.S. or Ph.D) in Mechanical Engineering or relevant field Experience in the following areas: FMEA (Failure Mode & Effects Analysis) High-pressure industrial gas systems Designing and analyzing energy and/or thermal management systems Designing gas and/or liquid processing systems Designing enclosures, busbars, and/or wire harnesses for electromechanical systems Leak detection methodologies and implementation Industrial-scale fluid handling systems What we offer Fully paid Medical, Dental, and Vision coverage Competitive salary and equity compensation commensurate with experience 401k Diverse and inclusive work environment Paid sick days and vacation Free lunches
