ZeroAvia is leading the transition to zero-emission aviation through the development of hydrogen-electric propulsion systems for civil and defence aerospace applications. As the world's only Design Organization Approved business focused exclusively on hydrogen-electric aviation, we have achieved significant flight test and regulatory milestones with the UK CAA and FAA and secured more than 3,000 pre-orders from airlines, OEMs and defence customers globally. Joining ZeroAvia means being part of a team pioneering the future of aviation and delivering lasting impact for the planet and its people.
As ZeroAvia scales its hydrogen-electric propulsion programmes, the Fuel Cell Systems Engineer will play a key role in transforming fuel cell technology into a fully integrated, certifiable aerospace product. Working across system architecture, requirements, interfaces and validation activities, you will bridge the gap between component technologies and aircraft-level integration. This role offers the opportunity to solve complex engineering challenges, collaborate across multiple disciplines and help deliver the systems that will enable safe, reliable and commercially viable zero-emission flight.
Responsibilities:
- Lead supplier management and development activities for LTPEM fuel cell systems, ensuring timed delivery, quality, and compliance with programme requirements.
- Act as the technical expert for LTPEM fuel cell, providing subject matter expertise and supporting design reviews for interfaces and balance-of-plant fluid systems.
- Support the test team in diagnosing, troubleshooting, and resolving fuel cell system performance issues during development and validation testing.
- Own and maintain fuel cell system documentation, including technical requirements, interface definitions, compliance evidence, and supporting design documentation.
