Job summary

Fourier is seeking a Senior Mechanical Engineer to lead mechanical design, analysis, integration, and validation of our commercial hydrogen production systems. This high-ownership role covers all subunits and the balance‑of‑plant envelope to tie them together.

This role interfaces with mechanical, electrical, and manufacturing teams to ensure safe HV/LV packaging, thermal management, and full integration into production enclosures.

Qualifications

• B.S. in Mechanical Engineering or equivalent; 6+ years in commercial product design and development.
• First-principles understanding of statics, mechanics, materials science, heat transfer, thermodynamics, and fluid dynamics.

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.
• 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 with electrical/electronics teams to integrate HV and LV systems into mechanical enclosures.
• Design packaging for HV assemblies with insulation, creepage/clearance and thermal management.
• Design and validate cooling technologies for electrolyzer stacks, power electronics, and components.
• Ensure enclosure designs meet electrical safety standards (UL, IEC, NFPA).
• Define ICDs between mechanical and electrical subsystems.
• Embed DFM/DFA principles from concept through production release.
• Create and maintain BoP docs, BOMs, P&IDs, and fluid specs.
• Hands-on experience with gas/water piping, including pressure ratings and leak testing.
• Develop test plans and lead validation activities.
