This position will manage preventive and corrective maintenance activities, quality assurance inspections, field audits, contractor performance, and maintenance documentation.

The ideal candidate combines strong knowledge of fiber optic networks and outside plant (OSP) construction with excellent leadership, organizational, troubleshooting, and quality-control skills.

• Monitor network outages, trouble tickets, repeat failures, and service-impacting issues; identify root causes and implement corrective actions.
• Coordinate emergency restoration and repair activities to minimize customer downtime and network impact.
• Ensure maintenance activities are properly documented and completed within established service-level expectations.
• Work closely with Network Operations, Engineering, Construction, Customer Service, and Field Operations teams to resolve network issues.

• Perform contractor audits and address performance deficiencies.
• Assist with contractor selection, performance evaluations, and corrective action plans.

Safety, Compliance & Documentation

• Ensure maintenance and field activities comply with company safety policies and applicable federal, state, and local requirements.
• Promote safe work practices involving aerial facilities, underground utilities, traffic control, confined spaces, and electrical hazards.
• Maintain accurate maintenance records, inspection reports, outage documentation, photographs, and asset information.
• Ensure GIS, network records, work orders, and maintenance documentation accurately reflect field conditions.
