Because we have strong reason to believe the position will be approved soon, we are proceeding with identifying qualified candidates and conducting interviews. **

The Mid Career Spaceflight Hardware Propulsion Engineer will:

• 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, review, and validate fluid-flow, pressure-system, thermodynamic, and thermal models.
• Develop and maintain engineering analysis and data-processing tools using Python, MATLAB, or similar software.
• Evaluate system architectures and lead or contribute to technical trade studies.
• Establish technical assumptions, document analysis methods, and communicate results and limitations.
• Assess component-to-system and system-to-vehicle technical effects.
• Provide technical oversight of propulsion components, suppliers, and hardware-development activities.
• Review designs, drawings, material selections, fabrication methods, assembly processes, and acceptance criteria.
• Support or lead propulsion hardware development from concept through fabrication, assembly, test, integration, and operation.
• Plan, coordinate, witness, or evaluate component- and system-level tests.
• Review acceptance-test data, qualification reports, verification evidence, and flight-readiness documentation.
• Evaluate test results and determine whether the available evidence satisfies technical and program requirements.
• Lead or support investigations of anomalies, nonconformances, and unexpected system behavior.
• Develop technically defensible recommendations for issue disposition and risk mitigation.
• Review and coordinate closure of variances, nonconformance reports, hazard reports, changes, waivers, reuse documentation, and certification action items.
• Develop verification approaches and support formal certification of propulsion systems and flight hardware.
• Assess pressure-system safety, cleanliness, contamination-control, and hardware-integration requirements.
• Support propulsion-system integration with spacecraft, test vehicles, or small satellites.
• Coordinate technical activities with NASA program and project offices, spacecraft organizations, suppliers, prime contractors, sub-tier contractors, and international partners.
• Organize and track concurrent document reviews, technical issues, risks, and action items.
• Delegate or coordinate reviews with appropriate hardware and technical points of contact.
• Prepare and present technical status, risks, nonconformances, and recommendations to program stakeholders.
• Participate in mission simulations, vehicle checkouts, propulsion console operations, and flight support.
• Provide technical guidance and mentoring to less-experienced engineers.
• Travel to supplier, test, integration, launch, or program locations when required.
• Perform other duties as required.
