Start Date: Immediate

JHNA,CTSi, and EXPANSIA have come together to form a Defense Technology platform named Aether Aerospace focused on delivering high-impact technologies, technology-enabled services and advanced manufacturing solutions to the U.S. Department of Defense and related national security customers. Backed by Falfurrias Management Partners, the platform brings together deep domainexpertiseacross Army, Navy, and Air Force and Space Force programs, digital engineering, systems integration, and specialized manufacturing capabilities.

The combined organizationoperatesas a multi-entity aerospace and defense technology and tech-enabled services and manufacturing enterprise positioned for scalable growth, operational excellence, and long-term value creation.

OVERVIEW

Full-time/Permanent Employee
Location: Dayton, OH (Travel: Up to 30% within continental United States)

Our client is seeking a Senior Propulsion Engineer to support the NOVASTAR program. This position will support a broad range of work involving the guidance, navigation, propulsion, control, software, modeling, and simulation of rocket-propelled aerospace vehicles.

The selected candidate willbe responsible foraddressing customer inquiries related to propulsion systems, including liquid rocket engines and solid rocket motors. Additionally, the candidate will be expected to formally respond to these inquiries through technical reports based on professional experience, background research, professional propulsion databases, rudimentary design analyses, and other technical resources.

The candidate must be able to work autonomously with minimal guidance. On occasion, the candidate will also be expected to contribute to collaborative technical reporting for our customers.
