• Rope access and suspended work platforms
• High-wind and remote site conditions
• Interface withrigging crews, rope access teams, and crane crewsto coordinate safe access

Data Interpretation & Engineering Support

• Analyze UT signals and map defect geometry, depth, and severity
• Correlate UT findings with:
• Visual observations
• Known failure modes
• Manufacturing layup and ply orientation

• Providereal-time guidanceto repair crews on:
• Defect boundaries
• Required scarf dimensions
• Repair acceptability

Reporting & Documentation

• Produce professional inspection reports including:
• Defect maps
• C-scan or A/B-scan images
• Damage classifications
• Repair recommendations

• Maintain digital inspection records and upload to GWT systems

• Support engineering teams with:
• Root cause analysis
• Warranty claims
• Insurance and customer documentation

Safety & Compliance

• Work in strict compliance with:
• OSHA
• GWO safety training
• Confined space and fall-protection procedures

• Perform job hazard analyses (JHAs) before inspections
• Maintain Stop-Work Authority when conditions are unsafe
• Other duties as assigned



Required qualifications
