Senior Hypersonics & Advanced Propulsion Engineer

iRocket is seeking a highly motivated and technically accomplished Hypersonics & Advanced Propulsion Engineer to support the development of next-generation hypersonic flight systems, advanced propulsion technologies, and solid rocket motors (SRMs).

This is an opportunity for an engineer with a strong background in hypersonics, high-speed aerodynamics, propulsion, thermal protection, or experimental aerospace systems to contribute to challenging aerospace and defense programs while expanding their technical expertise into solid rocket motor engineering.

The ideal candidate will have experience in both hypersonic technologies and solid rocket motors. However, prior SRM experience is not required for candidates with strong hypersonics backgrounds who are enthusiastic about learning and contributing to SRM design, development, manufacturing, and testing.

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.

• Support the research, design, development, and testing of hypersonic and high-speed aerospace systems.
• Perform or support aerodynamic, aerothermal, thermal, structural, and propulsion-system analyses for high-speed flight applications.
• Contribute to the development of hypersonic vehicle concepts, propulsion integration, launch architectures, and flight-test systems.
• Evaluate thermal protection systems (TPS), high-temperature materials, and structural solutions for extreme flight environments.
• Support experimental testing, ground demonstrations, flight-test planning, instrumentation, data collection, and post-test analysis.
• Work on high-speed flight vehicle integration, launch-system interfaces, and advanced payload deployment concepts.
• Collaborate with internal engineering teams, suppliers, research partners, and government customers to advance hypersonic capabilities.

• Work alongside iRocket's SRM engineering and propulsion teams to develop expertise in solid rocket motor systems.
• Participate in SRM design, analysis, manufacturing, assembly, testing, and qualification activities.
• Develop knowledge of SRM internal ballistics, motor cases, nozzles, insulation, ignition systems, and propellant grain design.
• Support propulsion-system integration, structural and thermal analysis, and engineering trade studies.
• Participate in static-fire tests, instrumentation, data analysis, hardware inspection, and engineering improvements.
• Progressively assume greater responsibility across both hypersonics and SRM programs, with opportunities to contribute to complete propulsion-system development.
• Translate technical requirements into engineering analyses, hardware designs, test plans, and development activities.
• Work closely with multidisciplinary engineering, manufacturing, and testing teams.
• Support technical design reviews, customer presentations, proposals, and program execution.
• Identify technical risks, troubleshoot development challenges, and recommend practical engineering solutions.
• Help transition advanced propulsion technologies from early development into repeatable manufacturing and production.

• Bachelor's degree or higher in Aerospace Engineering, Mechanical Engineering, or a closely related engineering field. Master's or Ph.D. preferred.
• 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…
