At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.
About the Team:
The Components team is responsible for all fluid control devices across Terran R, from propulsion to stage systems, enabling a more integrated and informed design approach. Engineers own every aspect of multiple products and integrate with partner teams such as Propulsion, Avionics, and Stage Fluids to ensure their components function seamlessly within the scope of the broader vehicle. With design, manufacturing, and test assets co-located, you’ll see firsthand how your designs perform and can iterate quickly based on real world data. We’re continuously advancing our products, including developing novel clean-sheet designs for upcoming vehicle and engine upgrades, while creatively improving existing designs to enhance performance, reliability, and manufacturability.
About the Team:
The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.
About the Role:
Propulsion Hardware Development Engineers are responsible for taking the Aeon-R engine from paper designs to highly reliable, high-performance hardware. This role requires deep engagement with both the design and production teams to ensure our designs are readily manufacturable and our manufacturing processes are reliable and production-ready. You will also be responsible for developing new manufacturing processes to improve Aeon-R engines and the Terran-R vehicle. You should have strong engineering fundamentals as well as a knowledge of aerospace manufacturing techniques to be an effective Hardware Development Engineer. The role demands close interaction with propulsion hardware, including defining build procedures and hands-on build and integration of hardware.
Responsibilities:
- Develop manufacturing processes, new techniques, and tools to enable high rate productions and increase engine performance
- Work hand-in-hand with the design and analysis teams to simplify our propulsion systems
- Participate in design reviews and lead design for manufacturing (DFM) initiatives
- Design test set-ups, coordinate and execute development, qualification, and acceptance testing of systems, and conduct data reviews
- Participate in test failure investigations and implement corrective actions
- Design, analyze, and procure tooling for piece part manufacturing and system testing
- Create and maintain development build and test schedules
About You:
- Bachelor’s degree in a science, engineering, technology, or mathematics field
- Hands-on hardware experience with fluid and/or mechanical systems
- Demonstrated drive to deliver on ambitious schedules, especially if unconventional & creative solutions are necessary to do so
Nice to haves but not required:
- 1+ years of related experience
