• Execute advanced interventions such as deep cleanouts, high-pressure milling, fishing operations, and stimulation support
• Oversee rig-up, pressure testing, operation, and rig-down of CTU and pressure control equipment
• Act as the primary technical authority on location during operations
• Monitor and interpret real-time operational data and make critical field decisions
• Troubleshoot complex surface and downhole equipment issues during live operations
• Ensure strict adherence to well control standards and HSE procedures
• Lead toolbox talks, risk assessments, and operational briefings
• Coordinate effectively with Field Supervisors, clients, and multi-service teams
• Mentor and train Field Specialists I/II and Field Operators
• Support job planning reviews and post-job reporting and evaluation
• Work with minimal supervision and may act as deputy or acting supervisor on location
• Hold significant technical authority during job execution
• Be accountable for operational integrity, safety, and efficiency in complex jobs
