Career Overview

Propulsion engineers design, test, and improve the systems that power aerospace vehicles. They work on rocket engines, spacecraft propulsion systems, jet engines, and emerging technologies that help vehicles travel through the atmosphere and space.

Without propulsion systems, rockets would never leave the launch pad, satellites could not reach orbit, and spacecraft could not travel to distant destinations.

Propulsion engineers work on projects such as:

  • Designing rocket engines

  • Testing propulsion systems

  • Improving fuel efficiency

  • Analyzing engine performance

  • Developing spacecraft thrusters

  • Solving engine-related problems

  • Researching new propulsion technologies

They often collaborate with aerospace engineers, systems engineers, and scientists to ensure vehicles can safely and efficiently complete their missions.
