Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The propulsion team is responsible for successful development of engines powering Terran R, owning their design from concept through launch and reuse. The team partners heavily with manufacturing, test, launch, and integration teams to develop engines in record time and support Terran R's first launch in 2026.
As a Turbomachinery Engineer II in Turbine Development, you will help advance the state of the art of turbine design for space applications. You will collaborate closely with propulsion development and manufacturing teams to incorporate improvements into future designs. You will work at the interfaces of design, development, and analysis of turbomachinery, helping build, test, and iterate on the full product lifecycle of Aeon-R engine systems.
Success in this role requires thriving in ambiguity and driving your own projects to completion. You must have the passion, tenacity, and resolve to work through challenging issues unique to rocket turbopumps. The ideal candidate comes from a fast-paced aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.
Relativity emphasizes autonomy, ownership, and impact at every level. You will solve problems that haven't been solved before, collaborate across teams, shape decisions, and see your work come to life in record time. This is an opportunity to leave your mark on the product, process, and culture at a pivotal moment—early enough to influence direction but far enough along that Terran R is tangible and gaining momentum.
**Requirements:**
- Degree in engineering or related technical field and 2+ years of relevant experience
- Experience with turbine design, performing aerodynamic and structural analysis
- Experience with LCF (Low Cycle Fatigue) and HCF (High Cycle Fatigue) methodologies
- Knowledge of industry standard turbomachinery design and analysis tools
- Strong communication skills
- Knowledge of turbopump assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks
**Nice to haves:**
- Experience with transient thermal/aerodynamic analysis
- Experience with forced response analysis
- Experience with in-situ mode shape/blade deformation measurement
- Experience overseeing turbomachinery development and/or test campaigns
- Proficiency in Siemens NX and Teamcenter
- Experience in a startup or agile development environment
- Experience working in a flight development program
