Cfd Jobs in California (NOW HIRING)

To support these efforts, Stratolaunch is seeking a Computational Fluid Dynamics (CFD) Engineer (Level II or Senior level) to join our advanced hypersonic design team. In this role, you will support the conceptual and detailed design of current and future Stratolaunch hypersonic vehicles, focusing on advanced CFD analyses, aerodynamic and aerothermal modeling, and the development of analytical tools. Responsibilities include contributing to design trade studies, detailed analyses, tool development, and flight test support. The ideal candidate will have a strong background in aerodynamics and aerothermal analysis, with hands-on experience modeling complex flow interactions across the subsonic to hypersonic flight regimes. 

ESSENTIAL RESPONSIBILITIES 

• Conduct advanced CFD analyses of captive carry and hypersonic vehicles, with emphasis on: 
• Interference effects (e.g., multi-body, control surface, propulsion-airframe interactions) 
• High-speed, high-enthalpy flows (Mach 5+) aero and aerothermal predictions 
• Develop, manage, and validate large CFD databases for a variety of vehicle configurations using CFD and supporting test data
• Contribute to aerodynamic and aerothermal databases by integrating analytical, numerical, wind tunnel, and flight test data
• Support trajectory analysis and optimization for current and future vehicles
• Analyze wind tunnel and flight test data as required to validate CFD models
• Develop and maintain CFD automation tools to support the team
• Collaborate with multidisciplinary teams to integrate CFD results into broader vehicle design and performance analyses
• Support business proposals and technical presentations to government and industry partners
