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 skilled and experienced Senior Fluid Systems Engineer to join our dynamic team and contribute to the development of the next generation of hypersonic vehicles. As a Senior Fluid Systems Engineer at Hermeus, you will play a pivotal role in designing, analyzing, and testing fluid systems for our hypersonic vehicles. You will collaborate closely with a multidisciplinary team of engineers to ensure the safe and efficient operation of our cutting-edge propulsion and thermal management systems.
