Senior Propulsion Engineer, Engine Systems & Test

About the Team:

The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.

About the Role:

This role may span several areas of our team depending on your skillset and the team’s needs at the time. The core responsibilities are driving engine system (architecture + CONOPS) trades, managing engine interfaces & negotiating requirements to optimize for the vehicle, and supporting engine system development overall. You may additionally support engine system analysis and simulation, engine testing, tool development, and more. In engineering at the system level, you will be expected not just to coordinate & facilitate amongst other technical teams, but to bring your own deep technical acumen to bear on problems in this highly technical role.

In order to be successful in this role, you should be capable of leading collaborative projects to completion with minimal oversight. You should also be a self-starter who is always looking for ways to improve yourself & learn more about the systems that interface with yours. Along with these high expectations comes the opportunity to have a significant influence on a fast-growing startup company and to make rapid professional gains in an environment that encourages growth and risk.

This role requires an average of 15% travel to our test & launch sites and may occasionally require shifted schedules or weekend work for critical milestones.

About you:

• Experience applying engineering fundamentals in fluid mechanics & thermodynamics
• Clear evidence of ownership, problem-solving skills, and effective team collaboration from school or work experience
• Demonstrated drive to deliver on ambitious schedules, even and especially if unconventional & creative solutions are necessary to do so
• Bachelor’s degree in a science, engineering, technology, or mathematics field
• Working knowledge of liquid-propellant rocket engines
• 5+ years of relevant experience, preferably in complex engineering system development and/or test environment

Nice to haves, but not required:

• Working knowledge of fluid components such as valves and instrumentation
• Working knowledge of engine subsystems such as combustion devices and turbomachinery
