Senior Structures Test Engineer

Relativity Space•Long Beach, CA

1d•$124,000 - $186,000•Onsite

About The Position

Relativity Space is developing the Terran R launch vehicle to meet demand for orbital launch capacity. The Factory Test team designs, builds, and operates hazardous testing equipment and operations at its Long Beach facilities, supporting work ranging from large structural tests to valve actuation and complex fluid systems. The Senior Structures Test Engineer applies technical expertise and project ownership to the design, development, and implementation of integrated test infrastructure supporting structural systems. Based in Long Beach, the role owns projects across the engineering lifecycle, from requirements development and design through fabrication, installation, commissioning, and operation. The work includes designing and analyzing test stands, supporting structures, pressure systems, and associated mechanical hardware, as well as hands-on support in factory and test environments. Work may involve elevated work areas, confined spaces, industrial environments, and outdoor conditions.

Requirements

Bachelor’s degree in mechanical engineering, aerospace engineering, or a 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 experience collaborating across multiple engineering disciplines.
Working knowledge of structural analysis and testing, 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 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, including 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, including work that may require elevated work areas, confined spaces, or occasional off-hours testing.

Responsibilities

Own the design and analysis of static and/or dynamic test stands, supporting structures, pressure systems, and associated mechanical hardware.
Develop requirements, system architectures, engineering drawings, technical approaches, and documentation for fabrication, installation, procurement, and commissioning.
Review technical work and identify and address structural and operational hazards to ensure designs meet applicable requirements, engineering standards, and safety considerations.
Support assembly, installation, commissioning, troubleshooting, and operation of test infrastructure, including hands-on work with hardware in factory and test environments.
