• Evaluate turbine operational data, maintenance records, SCADA information, and condition monitoring reports to identify trends and improve asset performance.
• Support troubleshooting of major mechanical components, including gearboxes, main bearings, main shafts, pitch systems, yaw systems, drivetrains, hydraulic systems, and lubrication systems.
• Develop engineering recommendations to improve turbine reliability, maintainability, and operational efficiency—including the implementation of engineering modifications, retrofits, and fleet-wide improvement projects.
• Support preventive, predictive, and condition-based maintenance (CBM) programs.
• Collaborate with field technicians, site managers, reliability engineers, and wind turbine manufacturers (OEMs) to resolve complex technical issues.
• Review engineering drawings, technical documentation, maintenance procedures, and service bulletins.
• Participate in Root Cause Analysis (RCA), Failure Mode and Effects Analysis (FMEA), and reliability improvement initiatives.
• Prepare technical reports, engineering documentation, and presentations for internal stakeholders and customers.
• Ensure compliance with company safety policies, industry standards, and regulatory requirements.
• Provide technical guidance and mentorship to maintenance personnel when required.

Requirements

• Bachelor’s Degree in Mechanical Engineering or related engineering discipline.
• Ability to manage multiple priorities and projects simultaneously in a fast-paced environment.
• Technically astute with strong attention to detail and expertise-based problem-solving skills.
