Low-Speed Propulsion Engineer

About the Role

We are seeking an experienced Low-Speed Propulsion Engineer to lead and contribute to the development, modeling, and experimental evaluation of propulsion concepts operating in subsonic and transonic regimes. You’ll serve as a technical contributor and mentor, providing subject-matter expertise in propulsion fundamentals while collaborating with multidisciplinary teams to solve complex problems that directly support national defense missions.

Responsibilities

• Lead propulsion analysis and design efforts for low-speed applications, including cycle analysis, performance modeling, and integration studies.
• Design, plan, and oversee experimental campaigns, including wind tunnel tests, ground-based propulsion experiments, and hardware evaluations.
• Develop, refine, and validate propulsion system models for use in design trades and system-level assessments.
• Mentor junior engineers and provide technical guidance in propulsion fundamentals and experimental best practices.
• Present technical findings and recommendations to sponsors, stakeholders, and leadership.
• Contribute to innovative research initiatives in advanced propulsion technologies, air-breathing systems, and hybrid propulsion concepts.
• Utilize propulsion modeling tools to conduct trade studies, performance assessments, and conceptual design studies of various weapon systems.

Requirements

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field.
• 5+ years of professional experience in propulsion system design, analysis, or testing.
• Demonstrated expertise in propulsion fundamentals, thermodynamics, and fluid mechanics.
• Experience with propulsion modeling and simulation tools (e.g., NPSS, CFD codes, MATLAB, Python).
• Strong track record of delivering technical results independently and as part of a collaborative team.
• Excellent communication skills with the ability to brief sponsors and document results.
• Ability to obtain a Secret level security clearance. Eligibility requirements include U.S. citizenship.

Qualifications (Preferred)

• Master’s degree or Ph.D. in Aerospace or Mechanical Engineering.
• Experience leading propulsion test campaigns, including facility coordination, test article design, and data analysis.
• Familiarity with multiple propulsion speed regimes to include solid rocket motors, ramjets, and scramjets.
• Working knowledge of uncertainty quantification, experimental methods, and system-level trade studies.
• Active DoD Secret or higher clearance.
