Job Description:

Long Beach, CaliforniaAt Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity's industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth - where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing 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 transform our vision into reality.About the Team:The mission of the Engine Manufacturing department is to deliver high-performing products and innovative manufacturing systems while driving continuous improvements in cost, quality, and lead time. Through cross-functional collaboration, high levels of accountability, and a focus on safety, we play a crucial role in building our reusable rocket, Terran-R. We are responsible for providing design feedback on new hardware iterations, pioneering and implementing advanced manufacturing methods and systems, and ultimately delivering engine and vehicle hardware for testing prior to launch. Over the past year, the Engine Manufacturing Team has successfully developed, iterated, and delivered processes and hardware for the first Aeon-R development engines. Now, we are entering a critical phase: producing flight engines that will pave the way for Terran-R's inaugural launch to orbit.About the Role:

• Own the AeonR integrated assembly from design release to integration to shipment. This will include developing the build process to meet production targets and reduce build issues.
• Develop processes and specs that directly impact the production rate of AeonR engines.
• Support production as needed to deliver engines by resolving build issues, receiving and implementing technician feedback, supporting BOM updates and build checkouts.
• Support work center development by considering assembly operations, tooling and capital equipment requirements, and rate targets. You will also support engine work center development across sites.
• Author test procedures and act as test conductor to verify as-installed hardware health and build integrity.
• Assist with developing the business tools and processes that will be used to manufacture the first launch vehicle. In parallel, help to define and pilot the long-term ERP, MES, and QMS solutions that will enable high-quality, efficient vehicle manufacturing.About You:
  • Degree in engineering or related technical field and 2+ years of relevant experience.
  • Strong communication skills, and ability to write detailed work instructions and process plans.
  • Ability to effectively investigate, resolve and screen hardware non-conformances.
