Integrated Performance Engineer Intern

At Relativity Space,we’rebuilding 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. Butthat’sjust 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'renot just executing tasks;you'resolving problems thathaven’tbeen solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’rein 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 storieswe’rewriting together.

Now is a unique moment in timewhereit’searly 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.

The Integrated Performance team owns the holistic view of how Terran R comes together, ensuring that every system on the vehicle and groundis 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 teamoperateswitha rare scale: large enough to support complex development, yet small enough that individual contributors have meaningful impact.

The Integrated Performance department at Relativity Spaceis responsible for ensuring that our rockets will achieve our overallobjectivesand satisfy stringent customer and government requirements. Our departmentcomprisesteams responsible for:

• Flight Sciences (Aerodynamics, Thermal Sciences, Loads, and Dynamics)
• Integrated Structures Analysis
• Guidance, Navigation, Control & Vehicle Performance (GNCP)
• Systems Engineering
• Mission Reliability
• Product Engineering.

We architect and execute analysis, simulation, operations, and test projects for all of Relativity’s hardware and software teams in pursuit of mission success. Overall, this department is critical to the launch success of Terran R!

• Launch vehicle trajectory design and optimization including launch availability and flight safety
• Process test data and flight data to ensure analysis predictions properly represent vehicle behavior
• Model stage separation including plume impingement to inform trajectory design of an entry vehicle
• Develop models and perform analysis for multiple payload deployment collision avoidance
• Develop dynamic loads and levels for launch vehicle hardware to design and test to
• Work with hardware designers to successfully execute to criteria established by the above
• Model coupled dynamics of engine actuators in a full vehicle dynamics simulation
• Upfront design work on creating a wall of truth for vehicle design
• Develop a script to automatically update a dashboard that displays abort values for testing and launch
• Perform CFD analysis of vehicle entry…
