Sr Mission Reliability Engineer

Job Description

Job Description

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 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 :

As a Mission Reliability Engineer, you will be responsible for working across all engineering disciplines to ensure mission-specific risks have been sufficiently mitigated and our launch system is ready for flight.

• Take ownership of risk tracking for a critical element of Terran R program (e.g. fluids, structures, avionics, engine) and manage risk of that element throughout testing and flight
• Organize and run flight readiness reviews to ensure technical readiness and flight data reviews to track action items and learnings from flight. Drive actions and findings to completion
• Provide real time (on console) support for test and flight as the authority for vehicle risk, communicating to leadership and executive team as required. Drive on-console resolution of technical risks to achieve successful test or flight outcome
• Support anomaly investigations as needed via use of tools such as fault trees, fishbones, and 5 whys. Work to resolve anomalies on day of test and launch in real time on console
• Perform independent assessments of subsystem and system designs to develop understanding of vulnerabilities, associated risk, and drive architectural decision-making to improve vehicle reliability
