Fuel Cell Mechanical Engineer Jobs (NOW HIRING)

Senior Systems Engineer – Fuel Cell SystemsStatus: Exempt (Salaried)Department: Fuel Cell Platforms - Systems EngineeringPosition SummaryPlug is building the global hydrogen ecosystem. We are the only company delivering a complete hydrogen platform, from production and liquefaction to storage, delivery, and power generation. They are integrated, end-to-end solutions designed to make hydrogen work at industrial scale across regions, industries, and applications.The Senior Systems Engineer serves as the technical authority for systems architecture within Plug’s Hydrogen PEM fuel cell product development — translating customer requirements into system and subsystem architecture, owning requirement traceability through production release, and leading cross-functional teams through structured stage-gate development. The ideal candidate brings deep systems engineering fundamentals, experience launching industrialized products in a regulated environment, and the ability to drive alignment across mechanical, electrical, controls, and software disciplines. Fuel cell experience is a plus; a track record of bringing complex power or energy systems from concept to production is the core requirement.
