3D Printing • Aerospace • Hardware • Robotics • Software • Manufacturing
We are building the future of aerospace.
The Role
Responsible for engineering design analysis, software tooling improvement, and collaboration across Vehicle Engineering for rocket development.
Summary Generated by Built In

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.

About the Team: 

Relativity’s Integrated Performance teams ensure that our products work across all systems and disciplines, from trajectory design to aerodynamics to reliability analysis and beyond. Our groups size the Terran R rocket, design its missions for customer success, reliability, and reusability, and ensure that every system on the rocket and ground is engineered correctly for the demanding environments of launch and entry. Recently, we completed the preliminary design and analysis of Terran R including Relativity’s first-ever work on launch vehicle reusability, spanning advanced trajectory simulations, wind tunnel testing, and structures analysis, among many other projects.

About the Role:

  • You will be responsible for:

    • Carrying out analysis for engineering design trades and driving design decisions based on the results.
    • Implementing, maintaining, and improving software tooling in a variety of languages, ranging from peripheral analysis utilities to core simulation capabilities.
    • Maintaining, establishing, and sometimes leading collaborative relationships with key teams across Vehicle Engineering.

About You:

  • A graduate degree (MS/PhD) in Engineering, Computer Science, Physics, or related field
  • 8+ of related experience working on projects that you utilize numerical techniques such as ODE's and optimization routines
  • Have previously worked on projects that required you to utilize numerical techniques such as ODE's and optimization routines
  • High proficiency in high-level programming languages (e.g. Python, Julia, MATLAB)
  • Demonstrated strong critical thinking skills and ability to solve problems from first principles

Nice to haves but not required:  

  • Experience with launch vehicles and trajectory design
  • Prior work in a startup or agile development environment
  • Demonstrated experiences in taking complex analysis results and clearly communicating conclusions and recommendations to decision makers
  • Experience working with advanced software development practices such as Docker, Continuous Integration/Continuous Deployment (CI/CD), and dependency management

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! To see some of the benefits & perks we offer, please visit here.

What We Do

Welcome to Relativity Space, where we're rewriting the rules of rocketry. We have built and launched the world’s first 3D printed rocket, Terran 1, and are now bringing to market Terran R, our reusable medium-to-heavy-lift launch vehicle. Our iterative development approach revolutionizes the process from design to flight, ensuring we can scale to meet customer needs.

Our focus is clear: provide exceptional launch services that are highly competitive in the market. We design and manufacture cost-effective, high-performance, and reusable rockets at an unprecedented pace and scale – setting a new industry standard.

At Relativity Space, we have two audacious goals: build the next great commercial launch company with Terran R, and become America’s leading force in additive manufacturing innovation. Both ladder up 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. That journey begins right here on Earth—designing, building, and flying rockets to deliver customer payloads to orbit.

A medium-to-heavy lift reusable rocket, Terran R is designed to meet the ever-growing need for launch capacity. Our iterative approach accelerates the design, test, and development processes, enabling high-volume performance and reliability, with lower costs and shorter time to market. Our 3D printing research and development is at the bleeding edge, setting the standard for a new era of large-scale additive manufacturing.

Why Work With Us

We believe in a future where interplanetary life fundamentally expands the possibilities for the human experience. In realizing this, our long-term goal is to create humanity’s industrial base on Mars. The first step toward this long-term vision starts here on Earth – building rockets and pushing the boundaries of additive manufacturing.
