SpaceX
Propulsion Engineer, Propulsion Simulation & Data Analysis
About this role
SpaceX is seeking a Propulsion Engineer to develop and maintain physics-based models of the Raptor rocket engine, conduct cycle analyses for design optimization, and perform data-driven anomaly investigation to support mission safety and engine performance prediction.
What you'll do
- Maintain and improve lumped-parameter thermofluid physics models of the Raptor engine
- Conduct engine cycle analysis to inform future design upgrades and thrust improvements
- Perform anomaly resolution using engine models and limited instrumentation data
- Develop deep understanding of rocket engine physics, performance variability, and measurement techniques
- Translate engine test data into accurate performance predictions for hundreds of simulations and hot-fire operations
- Support high-consequence decision-making for operations and component teams with data-driven insights
What they're looking for
- Rocket engine thermodynamics and cycle analysis
- Physics-based modeling and simulation
- Data analysis and interpretation
- Anomaly investigation and root cause analysis
- Control systems and optimization
- Instrumentation and measurement techniques
- Python or MATLAB programming
- Technical problem-solving under high-consequence scenarios
