About this role

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 Terrestrial Software team is building the foundation for an automated rocket factory and integrated launch platform. Their mission is to automate and streamline workflows across the entire lifecycle of Terran R, from raw material intake to launch operations and eventually manufacturing on Mars. Today, that means partnering directly with teams across design, materials, manufacturing, and test and launch to design, implement, and deploy end-user enterprise-wide applications, industrial automation, data analytics infrastructure, and next-generation AI to solve real problems and accelerate progress. Long term, the team is laying the groundwork for a modular, scalable software platform that can power highly autonomous operations on Earth and beyond. This is a team for builders and thinkers who thrive on cross-functional impact and want to shape the digital backbone of our future in space.
About the role:
Contribute to the frontend platform for our operator UI — including the application shell, design system, and shared data layer that teams use to build features
Implement frontend modules following the established architecture and contribution patterns that integrate into the unified application
Support the consolidation effort by migrating features and components from separate front ends into the unified operator platform
Work with real-time hardware telemetry, implementing UI components that render live data efficiently while meeting performance requirements
Learn from senior engineers, participate in code reviews, and apply best practices to improve code quality and your own frontend skills
About you:
Experience (typically 2+ years) building production web applications, with deep TypeScript and React expertise
Experience contributing to shared frontend codebases, component libraries, or design systems used by multiple teams
Foundational frontend performance skills: ability to use profiling tools, identify performance bottlenecks, and implement basic optimizations
Experience working with state management patterns and real-time data updates in React applications (e.g., Redux, Context API, WebSocket integrations)
Ability to collaborate effectively with senior engineers, receive technical mentorship, and contribute to architectural discussions.
Nice to haves but not required:
Real-time data visualization / charting, or industrial control, SCADA, or hardware-in-the-loop experience
Familiarity with binary streaming protocols (WebSockets/protobuf) and offloading work to Web Workers
Experience with a monorepo build system (Bazel) or embedding code editors (Monaco)
