Lead Propulsion Engineer, Integrated Design

Long BeachOn-siteFull-time

AI Summary

Leads a team focused on the design and analysis of integration hardware and engine layout for the Aeon-R propulsion system, guiding project execution, mentorship, prioritization, and cross-team collaboration.

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 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:

You will lead a team that is responsible for the design and analysis of integration hardware, as well as overall engine layout and packaging. This role will require managing a small team, requiring strong mentorship, project management, establishing priorities, communicating with leadership, providing technical guidance, and recruiting. Close collaboration with stakeholders within Propulsion Engineering (Combustion Devices, Turbomachinery, and Components) and external to Propulsion Engineering (Stage, Test Stand, and Integration) is essential. Designs and packaging trades will be informed by both fluid and structural analytical and computational models. You will strategically leverage 3D printing, as well as traditional manufacturing methods, to dramatically reduce the cost, weight, and part count of Aeon-R. To be successful in this role, you should be someone who thrives in ambiguity and knows how to lead (and guide) projects to completion.

About You:

Bachelor’s degree in a science, engineering, technology, or mathematics field
5+ years of experience with fluid systems design and/or structural design
Experience in mentoring and demonstrated leadership skills
Experience with computer aided design software
Experience with Finite Element Analysis (FEA) and commercial tools such as Ansys, Abaqus, or Nastran
Experience applying fluid, thermal, structural, and mechanical design fundamentals

Nice to haves, but not required:

Experience in leading teams
Experience in the design of liquid propulsion components and systems
Experience with Siemens NX and Teamcenter, specifically
Experience with large CAD model management, change management, and configuration management
Familiarity with aerospace standards (AS, NAS, SAE, etc.)
