Perform inlet/engine/airframe matching analyses and trajectory optimization. Conduct sensitivities and Monte Carlo analyses to support concept evaluation and risk reduction. Create concepts of operation, requirements development, and initial system architectures for advanced hypersonic concepts.
• 40% - Generate advanced designs and conduct performance analyses for liquid and solid rocket propulsion concepts and air-breathing engines. Develop configuration layouts and mass properties using CAD tools (Creo/NX). Create and maintain math models of propulsion systems characterizing thermodynamic, aerodynamic, fluid dynamic and mechanical operation. Utilize CFD tools for external aerodynamics, inlet performance, and nozzle analysis. Perform aeroheating analysis and stability & control assessments. Design and analyze engine control systems and control logic for solid fueled, liquid fueled, and air-breathing engines.
• 20% - Support Business Development activities including RFI/RFP responses, white papers, and customer briefings. Prepare and deliver technical presentations to cross-functional and integrated product teams. Lead peer reviews and participate in technical proposals describing design approach, relevant heritage, risk assessment and mitigation planning. Provide mentoring and guidance to less experienced engineers. Support engineering improvement initiatives including tool development and integration, and standard work procedures.
• Willingness and ability to travel up to 10-15%.

Required Qualifications:

• Bachelor's Degree and minimum 12 years of prior relevant experience in propulsion system design and analysis. Graduate Degree and a minimum of 10 years of prior related experience. In lieu of a degree, minimum of 16 years of prior related experience.
• Active Secret Security Clearance

Preferred Additional Skills:

• Bachelor's or Master's Degree in Aerospace Engineering or equivalent
