Mechanism Test Specialist

Castelion Corporation•Torrance, CA

About The Position

The Mechanism Test Specialist supports assembly, integration, execution, and troubleshooting of tests that turn designs into flight-ready mechanisms. Working closely with engineering, manufacturing, and operations, the specialist supports benchtop, environmental, subsystem, and vehicle-level testing of mechanical and electromechanical systems. The role builds and maintains test setups, integrates instrumentation, executes test procedures, and ensures accurate data collection for rapid hardware development and validation. This is a hands-on role for someone who thrives in a fast-paced, hardware-focused environment and solves mechanical challenges through testing and troubleshooting. The position may support flight tests and rocket motor static fires, and may require access to export-controlled information. If designated, it may also require obtaining and maintaining a U.S. Government security clearance or other authorization.

Requirements

Associate degree in Mechanical Engineering Technology, Electromechanical Technology, Aerospace Technology, or a related technical field, or equivalent hands-on experience.
3+ years of experience assembling, integrating, testing, or troubleshooting mechanical or electromechanical hardware.
Experience working with test instrumentation and laboratory equipment, including DAQs, oscilloscopes, power supplies, and sensors.
Ability to read and interpret engineering drawings, mechanical schematics, wiring diagrams, and test procedures.
Hands-on experience with mechanical assembly, precision measurement tools, and test equipment.
Strong mechanical aptitude and demonstrated troubleshooting and problem-solving skills.
Ability to document test results, identify anomalies, and communicate technical findings effectively.
Comfortable working across engineering, manufacturing, and operations teams in high-ownership environments.
Willingness to support extended hours, weekends, travel, and on-site operations during critical test campaigns.
Comfortable working in fast-moving environments where hardware testing drives development decisions.
Ability to access applicable export-controlled information without additional export licensing, as employment is contingent on this ability.
If the position is designated as requiring it, ability to obtain and maintain the required U.S. Government security clearance or other government authorization and meet applicable citizenship or eligibility requirements.
