Rocket Propulsion Engineer
Design and build solutions in the field.
What is a Rocket Propulsion Engineer?
Rocket Propulsion Engineers design, develop, and test rocket engines and propulsion systems. They work with various propellants, combustion processes, and nozzle designs to optimize engine performance and efficiency. Their responsibilities include system integration, performance analysis, and ensuring reliability and safety.
You split time between desktop analysis and hands-on test work: running CAE and performance simulations, performing detailed calculations, preparing technical drawings and specifications, and then inspecting installations or observing hot-fire tests to verify conformance. You confer with vendors and teammates, compile reports, and adjust designs based on inspection and test data to keep the project on schedule and within budget.
