Mass Properties Technician

GENERAL JOB SUMMARY:i

The Mass Properties Technician performs precision mass properties measurements to support aerospace payload development, integration, and qualifications. This role operates the facilityis spin balance machine (Raptor POI-3500) to determine mass, center of gravity (CG), moments of inertia (MOI), and products of inertia (POI) for a wide range of test articles. The technician prepares hardware for testing, configures the machine for accurate measurements, monitors data output, performs corrections based on mission requirements, and ensures all activities follow documented procedures and safety requirements. The position requires strong mechanical aptitude, attention to detail, and familiarity with sensitive measurement equipment in a mission-driven testing environment.

LOCATION:

• Crane, IN

ESSENTIAL JOB FUNCTIONS:

PRIMARY:

• Set up, operate, and monitor the spin balance machine to perform mass properties measurements including mass, CG, MOI, and POI.

• Prepare test articles, fixtures, and mounting configurations according to engineering requirements and test plans.

• Verify the calibration, readiness, and proper configuration of the spin balance system prior to testing.

• Collect, review, and document measurement data clearly and accurately in accordance with established procedures.

• Follow all safety protocols, equipment handling guidelines, and configuration control requirements.

• Work with engineers to troubleshoot fixtures, measurement inconsistencies, or machine setup issues.

• Maintain the spin balance machine, tools, and measurement equipment in a calibrated, clean, and ready-for-use state.

SECONDARY:

• Assist in developing or refining spin balance fixtures, adapters, and mounting solutions.

• Track consumables, hardware, and measurement accessories; support inventory and replenishment processes.

• Participate in continuous improvement efforts to enhance measurement repeatability, efficiency, and data reliability.

• Support pre-test readiness checks and post-test data reviews as required.

• Provide feedback on test instructions and technical documentation to improve clarity and execution quality.

• Coordinate with the Mass Properties Engineer, mission teams, and payload integration staff as measurement needs evolve.
