Test Engineer: Fuel Cell Systems

Kemble, Gloucestershire, United Kingdom
Full Time

ZeroAvia is a leader in zero-emission aviation, flying the world's largest hydrogen-electric aircraft since September 2020. Its focus is the design and commercialization of hydrogen-powered aviation solutions to address a variety of markets, initially targeting short-haul, sub-regional commercial flights up to 500 miles. To date, ZeroAvia has secured the UK CAA and FAA experimental permit to fly for its 6-seat aircraft powered by hydrogen-electric powertrain, passed significant flight tests, and is on track for commercial deliveries by 2024. Its achievements to date were rewarded by the UK prime minister by inviting ZeroAvia as a member to the UK Jet Zero Council. 

ZeroAvia’s powertrain development focuses on integrating hydrogen storage tanks, fuel cell systems, and electric motors, delivering a solution that will be not only without carbon emissions but also cheaper to operate. Commercializing the solution requires the establishment of a new clean aviation ecosystem, encompassing hydrogen production from renewable energy sources and tackling public perception of safety.

We are looking for talented, hands-on practical test-engineers to join our dynamic team of development engineers and scientists.
