What does a rocket engine design engineer do?

A Rocket Engine Design Engineer is responsible for designing, testing, and improving rocket propulsion systems. They work on creating engines that provide the necessary thrust for rockets to launch and operate in space. This involves detailed calculations, simulations, material selection, and close collaboration with other engineering teams to ensure safety, efficiency, and performance. Their work is crucial for both government space programs and private aerospace companies, and often requires a strong background in mechanical or aerospace engineering.
