Senior Mechanical Engineer, Additive Weld
Long Beach, California
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 w 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 w 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 w 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 Additive Technology team operates at the frontier of research and development, w creativity meets capability. This is an R D-driven environment w problems are open-ended and solutions are yours to define. You'll work alongside welders, robotics engineers, data scientists, and systems engineers at the intersection of hardware and software, creating an end-to-end additive manufacturing platform that serves a wide variety of applications. From exploring new materials to unlocking faster speeds, to designing complex,anic geometries that can't be built any other way, it's high-impact work that sets the foundation for the future of additive manufacturing.
About the Role:
Mechanical engineer that will collaborate with the additive weld team on designing and advancing proprietary metal 3D ing processes and equipment on Stargate ers
Capable of integrating concepts and principles of mechanical design and analysis of several different projects in a fast-paced environment - projects will vary in size and scale
Collaboration with weld, robotics, simulation, and process teams to derive requirements, set goals, and meet needs of the company and customers
Manage projects including vendor selection, fabrication, inspection, equipment installation, and commissioning of designs
Excellent analytical and problem-solving skills
Utilize rapid prototyping to iterate and refine designs quickly
About You:
Bachelor's degree or higher in Mechanical Engineering or a related field
5+ years of experience of design, build, and testing, of mechanical structures and mechanisms
Solid understanding of design for manufacturability and design for assembly including experience taking products from prototype design to production
Proficiency in CAD and creating drawings
Able to take initiative in a fast-paced environment
Strong communication and collaboration skills
Nice to haves but not required:
Experience with designing automation equipment and mechanisms
Solid understanding of general 3D ing design, limitations, and use
Experience with hands on fabrication including mills and lathes
Knowledge on running and programming a CNC is a plus
Ability to use rapid prototyping methods and technologies to advance designs
At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.
Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! , please visit .
