About the role

Propulsion Engineer focused on propulsion systems modeling, data analysis, and prediction of Raptor engine performance. Responsible for physics-based simulations, engine cycle analysis, anomaly resolution, and developing tools to translate test data into flight-ready predictions within SpaceX’s Raptor Systems Modeling and Control Team.

Responsibilities

  • Maintain and improve the accuracy of the lumped-parameter thermofluid physics model of the Raptor engine
  • Conduce engine cycle analysis to steer future-state engine design and thrust upgrades
  • Conduct anomaly resolution utilizing the engine model and sparse instrumentation
  • Develop a detailed understanding of the physics underlying rocket engine performance, sources of performance variability, as well as related modeling and measurement techniques
  • Maintain and improve the accuracy of the representation of the Raptor engine used in integrated vehicle simulations, control software validation and flight Monte Carlo analysis
  • Develop tools and portals to understand the sources of engine performance variability and enact improvements to manufacturing and engine hardware design
  • Automate processes and software tools that are used to predict test performance and generate flight performance predictions for GNC and flight software
  • Collaborate with engineers across the company to extend and improve interoperability among existing tools as well as to standardize hardware and software practices, tools, and methods to maximize functionality and value while minimizing future overhead and obsolescence

Qualifications

  • Bachelor's degree in computer science, engineering, or a STEM discipline
  • 1+ year experience with physics-based simulations of real dynamic systems
