Job description
At Relativity Space,we’rebuilding 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. Butthat’sjust 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'renot just executing tasks;you'resolving problems thathaven’tbeen solved before, helping develop a rocket, a factory, and a business from the ground up. Whetheryou’rein propulsion, manufacturing, software, avionics, or a corporate function,you’llcollaborate 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 storieswe’rewriting together. Now is a unique moment in timewhereit’searly 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 Structures and Mechanisms teamis responsible forthe full design, build, and test lifecycle of Terran R’s integrated structures and flight mechanisms. Whetheryou'areworking on highly iterative mechanisms that move or tight-margin structures thatshouldn’t,you’llget hands-on hardware ownership and see the rocket coming to life on the factory floor. Both teams fall under one department, sharing design principles, tools, and an integrated approach thatprovidesa comprehensive view of Terran R. Team members work on multiple parts, not just within a single subsystem, and are empowered to make decisions that directlyimpactflight hardware. Beyond first flight,you’llplay a critical role in refining for manufacturability and speed
Structures & Mechanisms
Your responsibilities will include, but not be limited to the following:
Support the design, analysis, and testing of electromechanical actuators (EMAs) and pneumatic actuator systems for aerospace applications.
Assist in creating CAD models, drawings, and documentation for actuator components and subassemblies, ensuring compliance with engineering standards.
Perform preliminary hand calculations and simulation support for actuator performance, loads, and kinematics.
Participate in hardware build and test activities, including setup, data collection, and post-test analysis.
Contribute to troubleshooting and root cause analysis for actuator performance or integration issues.
Collaborate with cross-functional engineering teams (mechanical, electrical, and test) to deliver reliable mechanism solutions.
About You
Current undergraduate or graduate student pursuing a degree in Mechanical Engineering, Aerospace Engineering, or a related technical discipline
Hands-on experience with mechanical design, prototyping, or analysis of structural or mechanism components
Familiarity with CAD tools (NX, SolidWorks, or similar) and exposure to FEA or engineering coding languages like Python or MATLAB
Strong interest in aerospace hardware such as actuators, linkages, latches, or deployable structures
Collaborative team member who thrives in fast-paced, multidisciplinary environments and is eager to learn
Nice to Haves but Not Required
Familiarity with CAD tools (NX) and basic drafting practices.
Experience with basic programming or scripting (e.g., Python, MATLAB) for data analysis or automation.
Exposure to finite element analysis (FEA) or other simulation tools for structural or thermal modeling.
Hands-on experience with prototyping, machining, or test lab equipment.
Structures Design
Your responsibilities will include, but not be limited to the following:
Design and develop piece parts, assemblies, and systems from early conceptualization up through full initial release – working with large machined metallic components, sheet metal, composites, formed panels, and more
Integrate critical design for manufacturing choices in direct coordination with the manufacturing engineering team
Perform packaging assessment of systems – resolve interferences, perform tolerance stack analyses, validate hardware stacks and fastener selections, integrate nominal gapping and shimming strategies, and more
Support BOM and configuration management of various systems across multiple vehicles
Create and release drawings as part of system release sprints post-CDR, including incorporating GD&T as primary definition
About You
Experience working on an engineering team/project designing and building hardware
1-2 years established CAD experience (SolidWorks, NX, CATIA, Fusion 360, etc.)
Demonstrates fundamental engineering principles and integrating them into design decisions
Able to work in large assemblies and navigate/manage large BOM's
Excitement to work on rockets and be onsite with real-world hardware
Nice to Haves but Not Required
Experience on a rocket team
1+ years experience with NX/Teamcenter PLM
1+ years experience with GD&T and drafting
