• Troubleshoot and diagnose equipment failures
• Repair equipment and restore tools to production
• Replace failed parts, components, and assemblies
• Perform equipment calibration, alignment, and verification
• Support tool uptime, reliability, and performance
• Troubleshoot electrical, mechanical, vacuum, robotics, motion-control, and wafer-handling systems
• Perform equipment installations, upgrades, and qualifications as needed
• Identify root causes and implement corrective actions
• Document service activity, repairs, parts usage, and technical findings
• Provide direct technical support to customers
• Work independently and take ownership of equipment issues through resolution

What We’re Looking For

• 2+ years of hands-on semiconductor equipment experience
• Field Service Engineer, Customer Engineer, Equipment Engineer, Equipment Technician, or comparable semiconductor equipment background
• Strong equipment troubleshooting and fault-isolation skills
• Experience performing PMs, CMs, repairs, calibration, and parts replacement
• Ability to read electrical and mechanical schematics
• Experience with vacuum, robotics, wafer handling, electrical, and electro-mechanical systems
• Ability to work independently in a semiconductor cleanroom environment
• Strong customer communication and technical documentation skills

CD-SEM, DR-SEM, SEM, e-beam, metrology, or defect review equipment experience is highly desirable.
