Principal Propulsion Engineer

Hermeus is an aerospace and defense technology company founded to radically accelerate air travel by delivering hypersonic aircraft.

The company aims to develop hypersonic aircraft quickly and cost-effectively by integrating hardware-rich, iterative development with modern computing and autonomy.

This approach has been validated through design, build, and test of the company's first combined turbojet-ramjet engine and is now being scaled through its first flight vehicle program, Quarterhorse.

Hermeus is also developing Darkhorse an uncrewed hypersonic aircraft designed to deliver unique asymmetric capabilities to the warfighter.

The Engines team is responsible for the engine development efforts that will propel all of Hermeus' hypersonic vehicles. The primary focus now is on the development of Chimera, which will provide the necessary thrust for Quarterhorse to take flight in the near future.

Through multi-disciplinary efforts to develop air-breathing engines that facilitate ground take-off and flight at supersonic and hypersonic speeds, we are addressing challenges that very few engineers have the opportunity to solve and doing so at a strategic and rapid pace.

It is an exciting time to join the team as we dive into the design of the first flight engines. Work and learn with motivated and passionate individuals.

Let's make some fire!
