Powertrain Responsible Engineer
Hermeus
Los Angeles, CA, USA
Posted on Feb 21, 2025
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.
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.

- Fully own critical flight hardware
- Work with system owners to architect and place components within systems
- Component level architecture and sizing
- Component design, analysis, development testing, qualification, production introduction
- Scope vehicle level operational methods and limits to ensure reliability and personnel safety through all phases of production and operation
- Making risk conscious decisions aligned with program posture
- Prioritize broad work scope to meet top company objectives
- Design/build cutting edge gearboxes, pumps, motors, and generators for hypersonic aircraft
- Design/build required testing infrastructure to validate, accept and qualify novel designs
