Turbomachinery Engineer - Fluid Dynamics

• If you hear “blade runner” and picture an impeller, this is for you
  
• If you can look at a head-flow curve and tell whether the pump is happy or about to cavitate, this is for you
  
• If you think the best CFD result is the one that matches the water-flow test and the hot-fire data, this is for you
  

• Design, analyze, build and test fluid aspects of flight turbopumps for liquid-fueled rocket engines, taking designs from concept to flight and owning every aspect of the turbomachinery design.
  
• Perform hydrodynamic sizing & flowpath design of impellers, inducers and diffusers, including high-power, low-flow-rate pumps, using meanline analysis and CFD.
  
• Run coupled aerodynamic/hydrodynamic and mechanical design, with detailed structural, thermal and life analysis of all turbopump components and assemblies.
  
• Own secondary flow analysis & axial thrust balance modeling to ensure hardware meets performance targets.
  
• Develop first-principles-based models, simulations and quick-estimate tools to predict turbopump performance and operability, and explore innovative concepts that push the state of the art.
  
• Work with manufacturing & assembly teams so that designs are producible, low in cost and weight, and quick to build, and drive manufacturing improvements
  
• Work closely with the engine, vehicle, feedline, valve and controls teams to integrate the turbopump and balance risk across the system.
  
• Prepare technical reports and present results and recommendations in design reviews & milestones.
  
• Create & maintain analysis tools and automation scripts to streamline the design and analysis workflow.
  

Requirements

• Master’s degree in an engineering discipline ; a degree in aerospace, mechanical or controls engineering, or any degree that sharpened your ability to model systems mathematically
  
• experience in the design, modeling or testing of liquid pumps or turbomachinery (relevant internship and project experience counts)
  
• Strong grounding in fluid mechanics, thermodynamics, heat transfer, structural analysis, and materials and processes
  
• Hands-on experience with CAD software needed for fluid systems design of turbomachinery
  
• A fascination with bringing space closer to everyone on Earth
  
• Must be able to work six days in a week, including extended hours and weekends as required.
  
• Willingness to travel in support of hardware testing and launch campaigns
  

• Experience carrying out rotordynamic analysis, including critical speeds, bearing and seal behavior, and stability, and assess turbomachinery failure modes.
  
• Experience reviewing drawings and ensure designs meet life, reliability and safety standards.
  
• Strong understanding of pump hydrodynamic and aerodynamic design, and of high-speed rotating equipment
  
• Experience with meanline analysis, and with turbomachinery and engine testing
  
• Experience with secondary flow and axial thrust balance modeling
  
• Experience in rotor dynamics, turbine and pump performance, impeller research and design, and turbomachinery failure modes
  
• Experience with turbomachinery manufacturing and design for manufacturability, including hands-on hardware builds
  
• Professional experience with CAD packages, and with simulation packages (for fluid flow, Mechanical, Thermal)
  
• Skill in building analytical and numerical models of engineering devices and processes, and proficiency in a scripting or programming language for automation
  
• Experience in a nimble engineering organization or a highly technical role that called for a scrappy, entrepreneurial approach under tight time and budget constraints
  
• Highly self-motivated, with strong communication and teamwork skills
