Senior GNC Engineer - Aircraft Engine Dynamics & Control



Atlanta, GA, USA
Posted on Wednesday, May 22, 2024
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.
The Senior Engine/Prop Dynamics and Control Engineer will be responsible for:
1) Engine/Prop dynamics modeling and control system design
2) Implementation of Engine/Prop dynamics + controller in6DOF high fidelity simulation environment + development
3) Supporting the development efforts on advanced guidance, navigation and control systems for our aircraft, as needed.
The successful candidate will work closely with our team of engineers and stakeholders to ensure that our aircraft meets safety, performance and efficiency standards.
Note: This position is open to both Senior Engineers and Level II Engineers. All candidates will be evaluated and placed into the appropriate level based on their experience and qualifications. Our goal is to capture a broad range of excellent candidates and match them with roles that best fit their career stage and skill set.
