Relativity Space
Combustion Devices- Propulsion Design Engineer II
Relativity Space, Long Beach, California, us, 90899
Overview
At Relativity Space, we aim to build the next great commercial launch company with Terran R and to lead in additive manufacturing innovation. We design, build, and fly rockets to deliver customer payloads to orbit, with Terran R providing increased launch capacity through an iterative approach that accelerates design, testing, and development while minimizing costs. Our 3D printing research and development pushes the boundaries of large-scale additive manufacturing. Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey as we work together to turn our vision into reality.
About the Team
The propulsion team is responsible for the successful development of the engines that power the Terran R vehicle. We own their design from concept through launch and reuse. Our team partners with manufacturing, test, launch, and integration teams to develop engines quickly and support Terran R’s first launch in 2026. You will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, maturing them to enable Terran R to reach space.
About the Role
You will own propulsion combustion devices and/or systems from concept through manufacturing and implementation. This role involves a range of skillsets: design, analysis (structural, thermal, fluid), manufacturing, test, project management, and communication. You will work across teams and departments and take ownership of projects you create. To be successful, you should thrive in ambiguity and be capable of leading collaborative projects to completion with minimal oversight. This role offers the opportunity to influence a fast-growing startup and to grow rapidly in an environment that encourages growth and risk.
About You
Bachelor's degree in a science or engineering field 2+ years of experience working in the development of propulsion components, combustion components, or related hardware This is an entry level position and professional work experience is not required Experience applying engineering fundamentals in thermodynamics, thermal, structural, and fluids
Nice to have but not required
Experience in a rocket engine development and/or test environment Clear evidence of ownership from school or work experience Working knowledge of engine subsystems such as combustion devices, heat exchangers, ducting Exposure to powder bed additive manufacturing and automation techniques
At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors. Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more.
