• Train junior field service technicians on startup procedures, troubleshooting protocols, and safe equipment operation
• Coordinate with third-party vendors and customers to resolve recurring equipment issues within integrated RUPS systems
• Travel to customer sites and manufacturing facilities for commissioning, factory testing, and training activities
