Job summary

Amentum is seeking a Mid Career Spaceflight Hardware Propulsion Engineer to join the JETSII Contract in Houston. The role focuses on propulsion and spacecraft pressure systems, requiring leadership in analysis, modeling, and test oversight.

You will develop fluid-flow and thermodynamic models, review designs, and coordinate with NASA offices and suppliers. Travel may be required to support hardware development and flight-readiness activities.

Qualifications

• Bachelor's degree in Engineering and 5–10 years of related experience.
• Demonstrated knowledge of fluid mechanics and thermodynamics.
• Working knowledge of heat transfer, engineering materials, mechanical systems, structures, or machine design.
• Experience analyzing propulsion, pressure, fluid, or thermal systems.
• Experience supporting hardware development, testing, integration, certification, or operation.
• Experience processing, analyzing, and interpreting engineering or test data.
• Ability to evaluate requirements, technical drawings, analyses, test plans, test results, and verification evidence.
• Ability to investigate technical issues and develop defensible engineering recommendations.
• Ability to assess component-level issues in a broader system and vehicle context.
• Strong written and verbal communication skills.
• Ability to organize and coordinate multiple technical activities and priorities.
• Willingness and ability to travel.

Responsibilities

• Apply fluid mechanics, thermodynamics, heat transfer, materials, structures, and machine-design principles to propulsion and spacecraft pressure systems.
• Independently perform or lead propulsion and pressure-system analyses.
• Develop and maintain engineering models and data-processing tools (Python, MATLAB).
• Evaluate system architectures and contribute to technical trade studies.
• Review designs, drawings, and fabrication methods; ensure acceptance criteria.
• Support propulsion hardware development from concept through test and operation.
• Plan, coordinate, witness, or evaluate component- and system-level tests.
• Provide technical oversight of propulsion components and suppliers.
• Mentor less-experienced engineers and travel as required.
