What you will do

• Design, develop, integrate, and support liquid propulsion systems, components, and subsystems from concept through qualification, production, and fielded operation.
• Perform propulsion analyses and trade studies covering combustion, fluid flow, thermodynamics, heat transfer, pressure, loads, performance, and system sizing.
• Develop engineering models, calculations, drawings, specifications, interfaces, bills of materials, and configuration-controlled documentation.
• Support the design of combustion chambers, injectors, turbomachinery, valves, regulators, feed systems, tanks, manifolds, and pressurization systems.
• Support component, subsystem, qualification, acceptance, and hot-fire testing; analyze test data and investigate failures.
• Collaborate with engineering, manufacturing, quality, test, suppliers, and program teams to resolve technical issues and improve propulsion hardware.

Requirements

• Bachelor’s degree in aerospace, mechanical, chemical, or a related engineering field with 4 years of relevant experience; a related master’s degree with 2 years of experience or 8 years of relevant experience may substitute.
• 4–10 years of professional experience in liquid propulsion, rocket propulsion, aerospace, defense, turbomachinery, fluid systems, or a related discipline.
• Experience designing, analyzing, developing, testing, or integrating propulsion systems or complex fluid and thermal systems.
• Working knowledge of fluid mechanics, thermodynamics, heat transfer, combustion, pressure systems, fluid system design, and propulsion performance.
• Experience with engineering analyses, models, calculations, technical reports, drawings, specifications, and hardware development or production troubleshooting.
• Must be able to obtain and maintain a U.S. security clearance if required and meet U.S. person/export-control requirements.

Nice to have

• Experience with cryogenic or storable propellants, pressure-fed or pump-fed architectures, injectors, combustion devices, turbopumps, valves, feed systems, or pressurization systems.
• Experience with MATLAB/Simulink, Python, CFD, FEA, NPSS, or similar engineering tools.
• Experience with aerospace or defense standards and qualification testing.
