Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The company is developing a rocket, factory, and business from the ground up, with a culture emphasizing autonomy, ownership, and impact at every level.
The Factory Test team is responsible for hazardous testing equipment and operations at the Long Beach facilities. The team designs, builds, and operates test assets from initial concept through commissioning and test execution, supporting everything from large structural tests to precise valve actuation and complex fluid systems.
As a Senior Structures Test Engineer, you will own projects across the full engineering lifecycle for structural test infrastructure. Your responsibilities include:
• Design and analysis of static and dynamic test stands, supporting structures, pressure systems, and associated mechanical hardware
• Development of requirements, system architectures, engineering drawings, technical approaches, and documentation for fabrication, installation, procurement, and commissioning
• Technical review of work to identify and address structural and operational hazards, ensuring designs meet applicable requirements, engineering standards, and safety considerations
• Support for assembly, installation, commissioning, troubleshooting, and operation of test infrastructure, including hands-on work with hardware in factory and test environments (may involve elevated work areas, confined spaces, industrial environments, and outdoor conditions)
You will be based in Long Beach and collaborate across multidisciplinary teams to solve challenging engineering problems while putting your hands on hardware.
REQUIREMENTS:
• Bachelor's degree in mechanical engineering, aerospace engineering, or related engineering field
• 5+ years of professional experience designing, analyzing, fabricating, commissioning, or operating mechanical, structural, or test systems
• Experience applying engineering principles throughout the design lifecycle, including requirements development, design, analysis, fabrication, commissioning, and/or operation of physical hardware
• Experience with 3D modeling and engineering drafting, including GD&T, and collaboration across multiple engineering disciplines
• Working knowledge of structural analysis and test (from hand calculations to advanced analysis)
• Fundamental knowledge of structures strength, stability and fatigue failure mechanisms, as well as additive and traditional manufacturing processes
NICE TO HAVES:
• Experience across both structural engineering and fluid systems, including test stands, hydraulic, pneumatic, cryogenic, pressure, or process fluid systems
• Experience with ASME B31.3, ASME BPVC, or similar industry codes and standards applicable to pressure systems or process piping
• Experience with advanced finite element analysis (nonlinear analysis or dynamic loading) using NASTRAN, ANSYS, or similar tools
• Hands-on experience with welding, machining, metalworking, hydraulics, piping, manufacturing, commissioning, or test operations
• Experience developing engineering standards, design practices, technical review processes, or automated engineering workflows using Python, VBA, or similar tools
• Experience supporting multidisciplinary engineering projects and test operations in manufacturing, factory, laboratory, or industrial environments
