- 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.

- 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.
