From Fourier's posting. “We” and “our” refer to the employer.
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.
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.
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
Design packaging solutions for HV electrical assemblies — including bus bars, power modules, and high-current connectors — ensuring proper insulation, creepage/clearance compliance, and thermal management
Partner actively with manufacturing engineering to embed Design for Manufacturability (DFM) and Design for Assembly (DFA) principles from the earliest concept phase through production release
Create and maintain full Balance-of-Plant (BoP) documentation including Bills of Materials, P&IDs, and fluid system specifications
Hands-on experience or strong familiarity with gas (hydrogen, nitrogen, oxygen) and water piping systems, including pressure ratings, material compatibility, and leak testing protocols
Develop test plans and lead laboratory test and validation activities to confirm product reliability, safety, and performance
Create and maintain PLM documentation including Bills of Materials, engineering drawings, design calculations, and FMEAs
