Additive Manufacturing Engineering Intern

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 Powder Bed Fusion Additive Manufacturing team is pushing the boundaries of what's possible in rocket propulsion hardware. Responsible for development, process, and production, the team oversees initial concept to final hardware with rigorous quality and precision. From developing print parameters on state-of-the-art 3D printers to enabling fast iteration for partner departments, the team plays a critical role in taking engine designs from concept to hot fire. The team was instrumental in producing Aeon 1 engines for Terran 1 launch and is now pioneering next-generation processes and designs for our Aeon R engines that will power Terran R. With flight hardware production scaling up rapidly, now is the time to join and make a direct impact.

About The Role:

• Develop, improve, and validate in-house additive manufacturing processes towards scaling future Terran R launch vehicle demand.
• Resolve manufacturing challenges and issues by implementing root cause corrective actions related to additive products and assets.
• Author and maintain standard operating procedures and work instructions for PBF production operations.
• Clear barriers to production operations with live issue resolution on the shop floor.

About You:

• Obtaining BS or MS in aerospace, mechanical, manufacturing, or industrial engineering.
• Demonstrated ability to define and implement a process from scratch and effectively communicate to a diverse team
• To be successful in this role, you need to be able to thrive in ambiguity, identify problems and quickly resolve them, and provide definition to the previously undefined
• You will need to balance a scrappy, get-it-done attitude with a vision for the long-term processes required for scaling and efficiency!

Nice to haves but not required:  

• Knowledge of design for additive manufacturing (DFAM) of metal components
• Familiarity with additive manufacturing technologies, specifically metal AM technologies like Laser-Powder Bed Fusion, WAAM, DED, etc
• Basic understanding of metallurgy, heat treatments, and additive manufacturing post-processing
• Familiarity with rocket propulsion system concepts
