Senior Propulsion Simulation & Data Analysis Engineer

Sr. Software Engineer, Propulsion Simulation & Data Analysis (Raptor) Hawthorne, CA SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal ofenabling human life on Mars. SR. SOFTWARE ENGINEER, PROPULSION SIMULATION & DATA ANALYSIS (RAPTOR) The Raptor Systems Modeling and Control Team is responsible for the power-balance, optimal control, and calibration of one of the worlds most prolific and advanced rocket engines. In addition to this we aid in root cause analysis for anomaly resolution, providing data and model driven insights supporting operations and components teams in high-consequence decision making. Our models and analysis are relied upon day-in-and-day-out to evaluate the safety and optimality of flight trajectories. With hundreds of engines, hundreds of simulations, and hundreds of hot fire operations, the work we do guides both the engine design process and operation of every single mission and engine test. In this role you will work with brilliant, passionate engineers to develop rapid, seamless processes to translate engine test data into accurate predictions of future performance for the most reliable and cutting-edge rocket engines in the world.
