Manufacturing Test Engineer II, Fluid Systems

Relativity Space•Long Beach, CA

19d

About The Position

The Manufacturing Test Engineer II owns the development, validation, and refinement of test assets and processes for mechanical, electrical, and pneumatic systems. The role collaborates with design and manufacturing partners to ensure production testing campaigns are efficient, reliable, and scalable. It drives technical execution of mechanisms and integrated assembly testing, including design integration, test equipment and tooling design or sourcing, test sequencing, mBOM development, work order creation, test training, and specification authoring. The engineer provides technical leadership in workcenter development, guiding assembly and test operations, safety compliance, tooling, and capital equipment in alignment with organizational objectives. The role also provides hands-on shop-floor support, addresses test issues, and provides upstream feedback to improve design for manufacturability, testability, and reparability. It analyzes test data, identifies recurring discrepancies, and leads cross-functional root-cause analysis and corrective actions. The engineer partners with design, production, supply chain, and quality teams to support manufacturing test processes.

Requirements

Bachelor's degree in aerospace, mechanical, electrical, manufacturing engineering, or a related discipline.
At least 2 years of experience building and testing hardware in a manufacturing environment.
Experience authoring test procedures to build and validate mechanical, electrical, and pneumatic assemblies.
Experience partnering with design engineering, manufacturing, and production teams to execute test procedures and lead investigations of test failures and anomalies.
Experience designing, implementing, and managing large-scope test systems and process improvements with minimal oversight.
Expert knowledge of safety standards, common test hazards, and appropriate mitigations.
Hands-on experience in at least two of the following: electromechanical or pneumatic assembly; electrical or pneumatic functional checkouts; integrated testing; leak checking; sensor checkouts; high-voltage systems (320V+); high-pressure pneumatic systems; or instrumentation and sensor setup.

Nice To Haves

Proactive self-starter with a track record of defining and implementing testing processes, driving execution across diverse teams, and delivering testing projects in fast-paced, production-driven environments.
Working knowledge of rocket subsystems, including structures, mechanisms, high-pressure gas systems, and avionics, and experience planning and conducting hazardous operations for aerospace hardware systems.
Knowledge of industry test standards such as SMC-S-016, MIL-STD-1540D, and MIL-STD-810G.
Experience with test automation, data acquisition and control systems, electrical test equipment such as oscilloscopes and multimeters, and pressure test equipment such as pressure regulators and flow meters.
