Posted on Wednesday, July 12, 2023

ZeroAvia is a leader in zero-emission aviation, flying the world's largest hydrogen-electric aircraft. Our 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 19-seater Dornier 228. We successfully flew the Dornier in January 2022 and we are now gearing up for commercial production. Our achievements to date have been rewarded with significant investment and being invited by UK Prime Minister to be a member of 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 not only be without carbon emissions but also cheaper to operate.

Role

Integrating a novel propulsion system within existing aircraft designs is an important opportunity in decarbonising aviation. To meet this challenge, ZeroAvia require an ambitious and capable senior stress engineer to help deliver effective solutions for modifying and re-certifying aircraft.

The successful candidate will predominantly work on integrating ZeroAvia’s propulsion system onto airframe primary structures including understanding and mitigating against the impact the modifications have on the original aircraft type certificate. The candidate may also be involved in the structural verification of the powertrain and power generation system itself along with rig design.

Job responsibilities will include the design and analysis of aircraft mounting structures and structural assessment of primary aircraft structures to accommodate novel powertrain systems. The work will involve material selection, proposing solutions to achieve stress, stiffness, durability and damage tolerance requirements and weight and cost optimization. Strong experience with FEA is essential, as well as hand calculations. Experience in aircraft preliminary design and working on CS-23 certified or regional aircraft programs a benefit.

Must have a strong mechanical engineering experience and ability to work independently. Experience with complex components and assemblies. Experience with Aircraft and Automotive drivetrain systems a plus. Knowledge of FAA, EASA, CAA regulatory structures, rules, and regulations a plus.
