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. We are seeking a highly motivated and experienced Senior Flight Software Engineer to join Hermeus, a hypersonic aircraft startup company. As a senior Flight Software Engineer, you will work closely with our hardware and systems engineers to design, develop, and implement software for our cutting-edge aircraft systems.
