At Fourier, we’re making on-site hydrogen universally accessible. Our breakthrough architecture enables highly modular and fully automated electrolyzer systems that scale efficiently across a wide range of operating conditions. Backed by leading venture investors, we’re building real hardware to accelerate the transition to a clean energy future.
About the RoleWe’re looking for a Manufacturing Engineer to help take our electrolyzer systems from prototype to scalable production. This role sits at the intersection of design, supply chain, and the factory floor. You’ll own manufacturing processes end-to-end—driving build quality, repeatability, cost reduction, and throughput as we scale. You will have the chance to bring up an electrolyzer system assembly line from scratch and shape how manufacturing at Fourier will transform.
This is a hands-on role working directly with hardware, technicians, and cross-functional engineering teams.
What You’ll DoDevelop, document, and optimize manufacturing and assembly processes for electro/mechanical/fluidic systems
Own manufacturing process flows, work instructions, tool selection, BOMs, and build documentation
Support prototype builds, pilot production, and transition to low- and mid-volume manufacturing
Identify and resolve manufacturing issues related to yield, quality, cost, and reliability
Collaborate with design engineers to influence DFM/DFA early in the design cycle
Work closely with supply chain and vendors to qualify parts, tools, inventory, and processes
Design or specify fixtures, tooling, and test setups to support production and validation
Support root cause analysis and corrective actions for build or field issues
Help define manufacturing KPIs and continuous improvement initiatives
BS in Mechanical, Manufacturing, Industrial Engineering, or equivalent practical experience
3+ years of experience in a manufacturing, production, or process engineering role
Strong understanding of mechanical assemblies, tolerance stack-ups, and production workflows
Experience supporting hardware builds from prototype through production
Comfortable working hands-on in a lab or factory environment
Ability to troubleshoot and solve problems at the system and component level
Clear communicator who works well across engineering, operations, and supply chain
Experience with complex electro-mechanical or fluid systems
Background in clean tech, energy, aerospace, automotive, or industrial equipment
Familiarity with Lean manufacturing, PFMEA, 5S, or continuous improvement methodologies
Experience scaling manufacturing in an early-stage or fast-growing companyWhy Join Fourier
