Mid Career Spaceflight Hardware Propulsion Engineer

Amentum•Houston, TX

About The Position

The Mid Career Spaceflight Hardware Propulsion Engineer supports NASA deep-space exploration programs by performing and leading engineering analysis, development, testing, integration, and certification of propulsion and spacecraft pressure systems. The role applies fluid mechanics, thermodynamics, heat transfer, materials, structures, and machine-design principles; develops and validates system models and analysis tools; evaluates architectures and technical trade studies; and assesses component, system, and vehicle-level effects. The engineer provides technical oversight of propulsion components, suppliers, and hardware development from concept through fabrication, assembly, testing, integration, and operation. Responsibilities include reviewing designs and verification evidence, evaluating test results, investigating anomalies and nonconformances, supporting certification and safety assessments, and coordinating technical activities with NASA, contractors, suppliers, and partner organizations. The position may also involve mission simulations, vehicle checkouts, propulsion console operations, flight support, mentoring, and travel to supplier, test, integration, launch, or program locations. The work is generally performed in an office environment but may involve indoor or outdoor work depending on the task. It may require extended sitting or standing and occasional lifting and carrying up to 25 pounds. Standard office equipment is used. Regular attendance is critical, and the schedule may need to be adjusted outside normal hours to meet peak periods and surge requirements. U.S. citizenship or permanent residency may be required, and the employee must be able to complete a U.S. government background investigation.
