Posted on Friday, January 12, 2024
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 an engineer to perform the mechanical design, specify the manufacturing processes, and define validation tests and build test equipment for hydrogen electrolyzer stacks. You will work closely with the electrochemists who have responsibility for the MEA. You will have overall responsibility for the design of the gasketing, clamping, and multiphase flow field and thermal design. You will manage the supply chain chain for the mechanical integration You will manage resources for assembly as well as working with our internal staff to aid in the design, assembly, testing, and optimization of our system. Fourier engineers work in a hands-on, collaborative environment to solve problems and push progress forward. Qualified candidates should have prior hands-on experience building and testing PEM electrolyzers and/or fuel cells.

Roles and responsibilities

  • Overall ownership of mechanical stack design, management and integration of components designed by other Fourier engineers
  • Perform two phase flow analysis to design the flow field components
  • Analyze the heat transfer from the system.
  • Design the clamping and gasketing system to provide reliable operation over many stop start cycles
  • Be the domain expert for mechanical stack materials.
  • Provide expertise in metal coating including spraying, plating, sputtering, and evaporation
  • Identify primary and secondary sources for all components; define OQC (outgoing quality control) for vendors and establish Certificates of Compliance (CoC’s)where required
  • Identification of fabrication process and design of tooling
  • Creation of test stands for evaluation of the performance and reliability of the system and its components
  • Establish metrics for IQC (internal quality control)



  • B.S. in Mechanical Engineering / Chemical Engineering / Materials Science or related degree/experience + 4 years industrial experience
  • Hands on experience with fabrication and testing of PEM based devices or similar technology
  • Portfolio should include examples of projects involving medium scale manufacturing and equipment test stands
  • Ability to perform cost models and skilled at design for cost down.


  • Advanced degree (M.S. or Ph.D) in relevant field
  • Experience with metal coating processes such as sputter, evaporation, spray, or plating
  • Expertise with manufacturing processes: conventional machining + etch + additive
  • Manufacturing experience with sealing of hygroscopic materials with compression-set
