Additive Manufacturing Modeling & Simulation Intern - Fall 2025New

Relativity Space
$28 - $36 an hour
Long Beach, California
Internship
May 29, 2025

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

Team:

Relativity is looking for an Intern to join our Additive Simulation Team within our multifaceted Additive Development Group. The Additive Simulation team at Relativity is responsible for developing modeling and simulation solutions to predict key physical phenomena of components during the manufacturing process, enabling other teams to make informed decisions using first-principles, data-driven and advanced intelligent methods. We value team members from diverse backgrounds who can contribute to the core responsibility of developing tools and models capable of advancing Relativity’s additive manufacturing technology.

What you'll do:

Our mission is to induce a paradigm shift in how rockets are built and flown.

The Additive Development group is looking for an intern to join us in solving the most complex problems in Additive Manufacturing. You will be expected to leverage your creativity and problem-solving skills to architect, develop, and deploy new tools, models, and processes focused on a wide array of physical, technical problems and phenomena related to manufacturing an orbital launch vehicle.

Your ability to exercise technical judgment in solving engineering challenges will be necessary to succeed in this internship!

Past intern projects (just a few examples!)

  • Tested flight quick disconnects
  • Implemented computer vision on the robots to implement live depth data
  • Worked on adding automated sanding/grinding capabilities to our print cells
  • Worked on test stand infrastructure to help run tests more often and more efficiently
  • Oversaw designing the PCB for the High Voltage Battery Management System (HVBMS)
  • Helped set up an anomaly detection framework for stargate printers
  • Modeling the manufacturing of rocket components
  • Printed rocket engine parts!

Skills/Competencies we're looking for (it’s not necessary to meet every individual skill requirement):

  • Obtaining BS, MS or PhD in Aerospace Engineering, Mechanical Engineering, Materials Science, Computer Science, Data Science or related field
  • Experience with finite element analysis and/or Multiphysics analysis
  • Experience in using scripting languages to automate modeling and simulation pipeline
  • Experience with automated and adaptive meshing techniques
  • Experience with calibration, verification and validation of models through physical testing
  • Experience in metal part design and topology optimization
  • Experience in data collection, manipulation and analysis
  • Experience with advanced manufacturing methods

We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required.

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!

Hiring Range:
$28 - $36 USD

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
