About The Position

Aether Aerospace, a Defense Technology platform formed by JHNA, CTSi, and EXPANSIA, is seeking a Senior Propulsion Engineer to support the NOVASTAR program. This role involves a broad range of work including the guidance, navigation, propulsion, control, software, modeling, and simulation of rocket-propelled aerospace vehicles. The engineer will be responsible for addressing customer inquiries related to propulsion systems, specifically liquid rocket engines and solid rocket motors, and formally responding through technical reports. The candidate must be able to work autonomously and occasionally contribute to collaborative technical reporting.

Requirements
