• Make critical decisions in the field, including recommending tool shutdowns for safety or yield protection when needed
• Document service activity, recurring issues, and corrective actions to support continuous improvement
• Manage spare parts inventory and support service-related administrative tasks (reports, quotes, etc.)
• Collaborate with engineering teams to share knowledge and improve service strategies
• Provide technical guidance to peers and assist with cross-training as needed

Requirements

• 5+ years of experience supporting semiconductor capital equipment (or similarly complex manufacturing equipment)
• Proven ability in hands-on troubleshooting of electro-mechanical systems (not IT/software support)
