Thermal Engineer

at  ZeroAvia

At ZeroAvia, we’re clean sky thinkers. For the world to achieve truly clean, guilt-free flight, we need a scalable solution; hydrogen-electric powertrains. As a leader in zero-emission aviation and a UK Jet Zero Council member, we’re designing and commercialising hydrogen-powered solutions that will positively impact the future of aviation, global connectivity, and the world.
Engineering designs our next-generation hydrogen electric engines. Working across Hydrogen, Propulsion and Integration divisions, they solve technical problems and help decarbonize aviation by finding solutions for electric propulsion, hydrogen storage, fuel cell technology, power distribution, thermal management and more.
Working closely with other engineering functions, assume responsibility for all aspects of thermal management of power and propulsion systems. Demonstrate recent practical experience and comprehensive knowledge of various thermodynamic technologies to help meet current and future system requirements. Be prepared to act as a subject matter expert and lead on thermal topics.
Dynamic approach to complex problem solving including utilising empirical methods, basic calculations from first principles and 1D & 3D simulation tools. Use CAD to create designs and drawings of related system components and assemblies, and maintain design data in PLM system in accordance with company and industry standards.
Self-starter, diligent, results focused and flexible. Aerospace experience, knowledge of CAA, EASA, FAA certification processes and objectives a plus.
