Propulsion Components Test Specialist III

At 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:

• Build & Commission new test assets and systems - incorporating fluid, mechanical, and electrical components – to unlock new capabilities or enhance existing ones. 
• Author & Optimize test sequences, procedures, and operational processes to support first-article development and transition into high-volume production. 
• Identify & Mitigate hazards in a fast-paced test environment to ensure the safety of all personnel. 
• Mentor & Train production technicians on test equipment operation and best practices. 
• Plan & Execute test campaigns in collaboration with Engineering to achieve Development, Qualification, and Acceptance test objectives. 

About You:

• At minimum: High School Diploma or GED. 
• 5+ years of relevant technical experience, including (but not limited to): 
  • Authoring & Executing Test Procedures 
  • Building Complex Fluid-Mechanical Systems 
  • Operating hazardous equipment with multiple sources of energy 
• Proficiency with Basic Office Software (Excel, Word, Outlook, Slack). 
• Demonstrated knowledge of safety standards, common test hazards, and appropriate mitigations. 
• Desire to teach and mentor less experienced team members. 
• Ability to precisely plan an activity, then execute according to that plan with minimal changes. 

Nice to haves but not required:  

• Associates Degree or Trade Certifications in pertinent disciplines: e.g., Aviation/Automotive Mechanic. 
• Familiarity with Industry Test Standards: e.g., SMC-S-016, MIL-STD-1540D, & MIL-STD-810G. 
• In-depth knowledge and experience with test automation, data acquisition, and control systems. 
• Knowledge of rocket engine components such as pumps, valves, regulators, check valves, as well as electric, pneumatic, and hydraulic valves, actuators, and other fluid system components. 
• Desire to work hands-on, as part of a team, in both the development and production phases of a product lifecycle.
