Avionics Electrical 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, Quarter Horse.

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