• Respond to equipment failures, operational issues, and site incidents in accordance with established incident management procedures.
• Support incident investigation and root cause analysis activities and contribute recommendations for corrective actions.
• Apply strong knowledge of operational procedures and compliance requirements to support safe and effective site operations.

Work Orders & Additional Projects

• Complete facility-related work orders and support infrastructure installations and modifications.
• Troubleshoot facility equipment and supporting systems to identify faults and minimize downtime.
• Support approved modifications to electrical, mechanical, cooling, and specialized systems.
• Participate in infrastructure upgrades, lifecycle replacement programs, maintenance initiatives, and site improvement projects.
• Recommend practical improvements that enhance infrastructure reliability, efficiency, and operational performance.

Collaboration
