Launch Mechanical/Electrical Engineer Intern

"

Launch Mechanical/Electrical Engineer 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 Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. The Cape is the only place where you see it all come together, offering a level of exposure and responsibility unmatched elsewhere in the program. This is where first flights happen, where history is built on top of history, and where the scale of what's underway is unlike anything in modern aerospace. The mission stays the same, but the work evolves with every milestone: from first launch to reuse, high-cadence operations, and beyond. If you're looking to define what's next in space launch and write a new playbook, not just repeat what’s already been done, this is where it happens.

Launch Engineer Interns Will Be On The Following Teams

• Launch Mechanical (Cape Canaveral, FL; Long Beach, CA) - Perform end-to-end design of launch hardware, utilizing CAD, FEA, and hand calculations, collaborating closely with the launch site civil and fluids engineering teams
• High Power (Cape Canaveral, FL) - Support design, installation, and activation of power generation and control, power distribution and protection, and sequencing systems used in launch operations

About The Role As a Launch Intern, you will help out and take on an active role in the development, build-up, activation, and operation of launch site GSE, including fluid systems (liquid oxygen, liquid natural gas, gaseous helium, liquid and gaseous nitrogen, hydraulics, water, and environmental control systems), supporting infrastructure, mating hardware and mechanisms, procedure development, system maintenance, operational concept of operations, GUI and automation development, and support launch/integration preparations and operations.

About You

• Current undergraduate or graduate student earning degree in mechanical engineering, aerospace engineering, or a related field.
• Ability to work in a fast-paced and intense startup environment.
• Basic knowledge of common fluid & structural components and instrumentation, such as valves, regulators, hydraulic actuators, pressure transducers, thermocouples, flow meters, accelerometers, strain gauges, load cells.
• Ownership of projects from beginning to end, with minimal oversight.

Past Intern Projects (Just a few examples!)

• Designed, built, and tested Aeon R engine ground spin start system
• Developed automation for precise control of ground system valve actuation
• Oversaw design and build of load test boxes for Avionics hardware in the loop testing
• Coordinated/developed interdisciplinary rocket and ground system architecture for Terran R
• Tested flight quick disconnects
• Implemented computer vision on the robots to implemented live depth data
• Worked on test stand infrastructure to help run tests more often and more efficiently
• Designed and 3D printed tools for rocket integration

Cape Canaveral internships will require your own transportation. We are an equal opportunity employer and value diversity at our company.
