Relativity Space is developing the Terran R rocket to deliver payloads to orbit using advanced 3D printing manufacturing. The Propulsion team focuses on designing, testing, and qualifying high-performance engines for the Terran R vehicle.
As a Propulsion Test Responsible Engineer I, you will be part of the Engine Systems & Test Team, responsible for the full lifecycle of propulsion test articles from design through qualification and flight. This is a highly varied role spanning multiple technical domains.
Key responsibilities include:
- Develop and execute test plans in collaboration with product owners and the Stennis test facility team
- Serve as the Responsible Engineer for propulsion test articles, owning exploratory operations and evaluations
- Troubleshoot technical challenges during test campaigns and analyze test hardware behavior
- Execute diverse technical tasks including writing test sequences, reviewing data, hands-on test article work, writing code, operating console during hotfire tests, and designing tooling
- Support engine subsystem troubleshooting and partner team investigations
- Contribute to engine system analysis, simulation, and trade studies
- Collaborate closely with component engineers, manufacturing teams, test facility teams, and launch operations
The role emphasizes ownership, autonomy, and impact at all levels. You will work in a culture that values bottoms-up decision-making and technical rigor, with the opportunity to shape both the product and the process. The team is currently advancing the flight configuration through qualification while exploring modifications for future engines including thrust upgrades and design for mass production.
This position offers the unique opportunity to work on cutting-edge propulsion systems at a critical inflection point—early enough to leave your mark on the product and culture, but far enough along that the Terran R vehicle is tangible and gaining momentum.
