Lead Hybrid-Electric Powertrain Engineer

Location: Los Angeles, CA (on site)

Package: $160,000 to $250,000 base + Equity + Comprehensive Benefits

iO Associates have partnered with a well funded, early stage pioneer in sustainable aviation, with serious financial backing and a multi-billion dollar sales pipeline already. They have technology that is already proven in the sky, making them a leading contender to dominate the space.

They’re at a critical inflection point as they move through certification and commercialisation. We need a Lead Engineer to own the hybrid powertrain unit, integrating the reciprocating engine, electric motor/generator, and auxiliary equipment.

This is a rare opportunity to get in early, make your mark and take ownership of a powertrain system that will fundamentally change how the world flies.

You will be:

  • Owning the firewall-forward fluid, thermal and structural auxiliary equipment through to commercial readiness.
  • Designing, building and running powertrain test fixtures – standalone bench and on-wing configs.
  • Setting up and managing instrumentation across the powertrain system, to build out test stand GUIs.
  • Executing dynamometer and thermal management testing, then owning the data analysis and certification reporting.
  • Feeding directly into commercial certification reviews

You must have:

  • A solid background in aviation reciprocating engine systems – you must know these inside out.
  • Powertrain integration or test environment within aerospace.
  • Proven track record running dynamometer and thermal management test programmes.
  • Working knowledge of high-voltage and high-power systems and safety requirements.
  • Direct experience on aviation certification programmes for powertrain systems.
  • Background in electric/reciprocating/gas turbine powertrain engineering.
  • Hands-on work with vibration testing and data systems.
  • Degree educated in Mechanical, Aerospace, Electrical or a related engineering discipline.
