Description
Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.
As a Powertrain Responsible Engineer you will own the mechanical components and assemblies that generate and transmit power in all forms (fluid, mechanical and electrical) throughout our hypersonic vehicles. This includes gear boxes, generators, motors, and turbomachinery. This highly interdisciplinary role requires strong 1st principles in mechanics, fluid dynamics, thermal analysis, materials science, and manufacturing. You will need to be able to communicate requirements clearly and concisely in a rapidly changing environment while driving the development of cutting-edge hardware that will accelerate the future of hypersonic travel.
