About The Position

We are looking for an engineer who enjoys solving difficult technical problems, developing real hardware, participating in testing, and taking engineering concepts from initial design through demonstration. This role involves supporting the research, design, development, and testing of hypersonic and high-speed aerospace systems, as well as developing expertise in solid rocket motor systems. The engineer will perform analyses, contribute to vehicle concepts, evaluate thermal protection systems, and support experimental testing. There are opportunities to progress to greater responsibility across both hypersonics and SRM programs, contributing to complete propulsion-system development. The role also includes translating technical requirements into engineering execution, supporting design reviews, identifying technical risks, and helping transition technologies from development to production.

Requirements

Bachelor's degree or higher in Aerospace Engineering, Mechanical Engineering, or a closely related engineering field.
Relevant engineering experience in hypersonics, high-speed aerospace systems, advanced propulsion, aerothermodynamics, or related technologies.
Demonstrated technical involvement in at least one relevant aerospace development, analysis, research, or testing program.
Strong understanding of engineering fundamentals, including thermodynamics, fluid mechanics, propulsion, heat transfer, structural mechanics, or combustion.
Experience with engineering analysis, simulation, mechanical design, experimental testing, or hardware development.
Ability to work collaboratively across multiple engineering disciplines and solve technical problems independently.
Strong interest in developing expertise in solid rocket motors and willingness to work across both hypersonics and SRM programs.
Willingness to participate in hands-on development, manufacturing activities, and ground or flight testing.
Ability to work on-site in New York or Texas and travel to test facilities as required.
Ability to meet applicable U.S. export-control requirements for assigned work.
