• Review test data, technical reports, drawings, requirements, and verification documents.
• Help investigate hardware anomalies, nonconformances, and unexpected test results.
• Support the preparation and closure of action items, variances, hazard reports, change documentation, and other certification products.
• Assess how component designs, changes, or anomalies may affect the propulsion system or spacecraft.
• Support compliance with pressure-system safety, hardware cleanliness, and contamination-control requirements.
• Assist with propulsion-system integration into spacecraft or test vehicles.
• Participate in mission simulations, vehicle checkouts, console activities, or flight operations as assigned.
• Coordinate technical work with engineers, technicians, analysts, project personnel, suppliers, and contractor organizations.
• Prepare and present clear technical status updates, analyses, and recommendations.
• Travel to supplier, test, integration, launch, or program locations when required.
• Perform other duties as required.
