About Relativity Space

Relativity Space builds reusable rockets that make access to space more reliable and routine—empowering science, exploration, and innovation beyond our planet. Backed by General Catalyst, Y Combinator and Lux.

About the role

As a Staff Materials and Process Engineer, you’ll bring deep metallurgical and manufacturing-process expertise into the Awerx design-for-manufacturing (DFM) systems. You’ll turn what you know about how metals solidify, deform, crack, and machine into the rules, models, and constraints our agents use to design and plan aerospace hardware. The focus is hybrid manufacturing. Found on 1752vc Careers, the job board for startup and VC roles.

What they're looking for

  • Bachelor’s degree in Materials Science, Metallurgy, Mechanical Engineering, or a related field
  • 10+ years of materials and process engineering experience on aerospace or other high-reliability metal hardware
  • Expertise in physical metallurgy across nickel superalloys, copper alloys, aluminum, and titanium, including solidification, phase transformations, heat treatment, and defect formation
  • Hands-on experience developing or qualifying directed energy deposition processes (WAAM, laser DED, or electron-beam DED) and integrating them with CNC machining
  • Experience designing and running test programs (coupons, metallography, NDE, mechanical testing) and generating statistically based design allowables (A- and B-basis) to NAVSEA, MMPDS, or comparable requirements
  • Proficiency in Python or a similar language for data analysis and scripting
More about this role

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...
