Specialist Liquid Hydrogen Engineer

ZeroAvia produces practical zero emission aviation powertrain targeting 9-19-passenger airplanes to start replacing dirty jet fuel.

ZeroAvia is a leader in zero-emission aviation, flying the world’s largest hydrogen-electric aircraft since September 2020. Our focus is the design and commercialization of hydrogen-powered aviation solutions to address a variety of markets. We work with leading airports, utilities, fuel service providers, and technology partners and we are building the future today.

ZeroAvia’s powertrain development focuses on tightly integrating H2 fuel cell power systems and storage, along with electric drivetrain components, to deliver a unified solution that is both environmentally friendly and economically superior to traditional aircraft drivetrain solutions.

Our Infrastructure Team is focused on supporting the decarbonization of airports through novel electrolytic operations and fueling transportation through liquid hydrogen. It is a small, highly talented, focused, and motivated team and we believe it will be possible to accelerate the productization of liquefaction, grid stabilization, and electrolyzer technologies within this decade.


We are seeking an experienced Hydrogen Engineer to join our Infrastructure Team, with opportunities to progress to a technical leadership position. This position involves close collaboration with product delivery, project management, and aircraft hydrogen teams, and plays a key role in driving hydrogen and energy infrastructure via a compelling use-case, namely airports as energy hubs, and aircraft as a primary off-taker. The successful candidate will possess excellent creative engineering skills, project management expertise, strong leadership qualities, and organizational abilities to oversee a diverse and expanding set of complex programs involving liquid hydrogen, gaseous hydrogen, and conversion technologies.

Although project sizes may be modest initially, we anticipate that they will become larger and more complex over the next 12-24 months, with multiple stakeholders and eventual scaling to multi-million dollar investments. Initially, this role will involve opportunities in the US, UK, and EU.

  • Excellent interpersonal skills, as well as good written and oral communication skills


  • Degree in Chemical Engineering or equivalent
  • Experience in building Liquid Hydrogen systems or other cryogenic systems
  • Have operational exposure to a variety of disciplines leading to design integration roles
  • Expertise in process safety
