HIL Engineer

  • Kemble, UK
  • Engineering

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.

A key engineering role working closely with the product delivery, project management and aircraft hydrogen teams, this role needs strong creative engineering skills, project engineering and organisation to manage a thriving and growing set of complex programmes in liquid hydrogen, gaseous hydrogen and conversion technologies. Project sizes may be small today but are complex and we expect them to grow in the next 12-24 months to multi-stakeholder projects that will eventually scale to multiple million-dollar investments. The role will primarily be based out of the UK, with the opportunity to travel.
