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 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:

In this role, you will lead a team of ~20 engineers who own development of the Aeon engineseries at the system level. The team’s work spans component & integrated system hotfiretesting, thermofluids simulation, system-level architecture, requirements, and interfaces; andmore. We collaborate closely with propulsion design engineers, our manufacturing team, ourStennis test team, and our Cape launch team to deliver engines that will successfully propel theTerran rocket to orbit. We strive for continuous improvement and support the development ofour technical hardware and human teammates alike.

Your responsibilities will include the following:

• Lead, mentor, and develop a team of propulsion development engineers, fostering aculture of growth & continuous improvement
• Solve a variety of technical problems across broad ranges of timeframe, scope, andcomplexity
• Collaborate with propulsion & vehicle design, manufacturing, software, and operationsteams to ensure seamless integration between your team’s activities and overall vehicledevelopment
• Oversee the planning, execution, and analysis of engine & component hotfirecampaigns, as well as engine support of stage test & launch campaigns
• Oversee the system-level development of current and future engines (architecture,CONOPs, simulation, interfaces), including large upgrades such as engine cycle changes
• Set team priorities & allocate resources between different products or functions
• Drive improvements in processes, tools, and automation
• Identify and mitigate risks related to engine development, ensuring timely issueresolution and program success
• Scale the team’s bandwidth & abilities through recruiting & training to meet futureengine & vehicle development needs
• This role is full-time onsite in Long Beach, CA, and requires an average of 15% travel to our test & launch sites
• This role may occasionally require weekend work for critical milestones

About you:

• Bachelor’s degree in a science, engineering, or technology field
• 8+ years of relevant experience in a complex engineering system development and/ortest environment
  • Including 2+ years of direct experience with liquid-propellant rocket engines
  • Including 2+ years of direct experience leading teams of multidisciplinaryengineers
• Experience mentoring, managing complex interdisciplinary projects, supportingcontinuous improvement of the team around you and participating in growing yourteam
• Demonstrated engineering fundamentals in fluid mechanics and thermodynamics
• Demonstrated drive to deliver on tight schedules, especially when unconventional &creative solutions are necessary
