ELECTRIC DISTRIBUTION MECHANIC (3879) (REVISED 11/25/25)

Hermeus is a startup developing hypersonic aircraft to radically accelerate air travel. At Mach 5, more than twice the speed of the supersonic Concorde, passengers will be able to cross the Atlantic in 90 minutes. On the path to hypersonic passenger aircraft, Hermeus is partnering with government agencies including the US Air Force and NASA to develop a series of autonomous aircraft that derisk the technology and solve urgent national security challenges. These products provide the data and confidence necessary to certify, produce, operate, and maintain safe and comfortable commercial aircraft. Hypersonic aircraft have the potential to create trillions of dollars of new global economic growth per year, unlocking significant resources that can be utilized to solve the world’s greatest problems.
