Job description

Description

Primary Role: Performs mid-level, complex mechanical assemblies utilizing automated/semi-automated assembly equipment. Executes precision functional testing including pressure, fluid flow, standard leak, and specialized Helium leak testing

Key Responsibilities:

Advanced & Automated Assembly:

• Set up and operate or semi-automated assembly equipment (e.g., automated fastening systems, or computer-controlled torque systems).
• Perform complex, multi-tier mechanical assemblies requiring tight tolerances, intricate internal components, and precise alignments

Pressure, Flow, and Leak Testing

• Hydrostatic & Pneumatic Pressure Testing: Set up and safely operate high-pressure test benches to verify structural integrity and proof-pressure limits
• Flow Testing: Connect and execute fluid/airflow testing to validate that components meet specific volumetric or mass flow-rate requirements
• Helium Leak Testing: Operate specialized Helium mass spectrometer leak detectors. Perform hard-vacuum or sniffing testing techniques to detect micro-leaks to strict aerospace leak-rate specifications

Inspection & Quality Control

• Interpret complex aerospace blueprints, schematics, engineering drawings
• Review and validate data logs from automated test equipment to ensure compliance with acceptance criteria

Process Control & Efficiency

• Monitor test fluid cleanliness, system pressures, and gas supplies (Helium/Nitrogen), proactively replacing filters or culinders to prevent downtime
• Maintain cycle-time awareness, tracking actual assembly and test times against standards to optimize throughout
• Stage and manage production flow using the ERP system, ensuring immediate transition between assembly and testing cells

Troubleshooting & Maintenance

• Diagnose and resolve common test stand alarms, fixture leaks, and assembly
• Perform routine maintenance and daily calibration verification on test benches, gauges

Mentorship

• Demonstrate a willingness and ability to mentor and train Assembly teammates on proper mechanical techniques, equipment operation, and safety

Requirements

• Experience with finite assembly
• Experience with conducting pressure, flow, and leak testing
