Exercise engineering judgment, creativity, and technical leadership to resolve technical issues and prove/disprove the feasibility of ideas, innovations, and modifications to liquid propulsion system components and overall performance.
Provide technical oversight to aerospace engineering studies with elements or components from related disciplines such as systems engineering, thermodynamics, heat transfer, fluid dynamics, and integrated propulsion system design and operation.
Provide recommendations on the development and production of human-rated liquid propulsion systems while navigating dynamic and unpredictable environments with multiple variables and unknowns affecting planning, design, risk, cost, and schedule.
Provide technical oversight to the development and design of complex aerospace liquid propulsion technology, equipment, or systems that impact major programs and result in major advancements in the state-of-the-art of broad technologies.
Serve as point of contact for project and program offices in executing assigned responsibilities as the Center's engineering expert for development and design of complex aerospace liquid propulsion systems.
Manage and further develop partnerships with external organizations integral to propulsion system research, development, and production (e.g., international counterparts, prime contractors, subcontractors, academia).
Manage engineering efforts for programs/projects involving human space flight propulsion systems and vehicles, including design and operational requirements definition, hardware testing, safety, integration, flight certification, and operations.
