Job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launchcapacity. But that’s just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science, exploration, and innovation, pioneering progress that reaches beyondthe 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. Nowis a unique moment in time where it’s early enough to leave your mark on the product, the process, andthe culture, but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Integrated Performance team owns the holistic view of how Terran R comes together, ensuring that every system on the vehicle and ground is capable of achieving our ambitious objectives. The team works across the full launch system, from trajectory design and aerodynamics to reliability analysis and beyond, with direct influence on all parts of the product lifecycle, from conceptual design to post-flight data review. Beyond analysis, team members engage hands‑on with hardware and operations, with the mission and authority to drive meaningful programmatic change. With a unique organizational structure, the integrated performance team spans multiple technical domains and embeds directly with partner teams to solve the hardest multi‑disciplinary problems. The team operates with a rare scale: large enough to support complex development, yet small enough that individual contributors have meaningful impact.

About the Role:

Closely collaborate with key design teams to integrate the latest design data into full simulations of customer missions

Develop and leverage software tooling to optimize launch and orbital trajectories across key customer missions

Lead interdisciplinary design trade analyses to inform critical decisions about the vehicle, mission trajectories, and ConOps

Define and maintain high‑level vehicle and trajectory design requirements to inform the overall design process

Implement, maintain, and improve software tooling across a variety of languages, from core simulation capabilities to peripheral analysis utilities

Establish and lead cross‑functional collaboration with key teams across Vehicle Engineering

About You:

An undergraduate or graduate degree (BS/MS/PhD) in Engineering, Computer Science, Physics, or a related field

1+ years of relevant full‑time work experience with demonstrated ability to solve complex problems from first principles

Direct experience on rocketry, space systems, or equally complex hardware systems

Strong proficiency in high‑level programming languages (e.g. Python, Julia, MATLAB) and setting up complex simulation processes

Ability to complete projects with end‑to‑end ownership and a high degree of independence

Comfortable working in a fast‑paced and intense startup environment

Nice to haves but not required:

Familiarity with launch vehicle trajectory design and optimization

Have previously been a leading contributor on complex multi‑disciplinary engineering analysis projects

Prior work in a startup environment

Experience working with advanced software development practices such as Docker, Continuous Integration/Continuous Deployment (CI/CD), and dependency management
