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 Hermeus Test discipline owns the cradle to grave testing of the fastest unpiloted reusable air breathing aircraft on the planet. These are extraordinary vehicles, and we're seeking extraordinary Test Engineers who can drive, thrive, and survive in a Mach 5 environment.

At Hermeus, we are constantly iterating and integrating. We test early and often to minimize technical and program risk. We build the test campaigns that support our full range of test programs spanning development, operational and certification testing.
