• Monitor equipment lifecycle risks and develop long-term support strategies.
• Stay current with emerging technologies, supplier roadmaps, and industry best practices to identify improvement opportunities.
• Develop and enhance equipment health monitoring, Fault Detection and Classification (FDC), and predictive maintenance strategies.
• Analyze equipment data, alarms, sensors, and performance trends to identify degradation and prevent failures before they impact production.

Troubleshooting & Technical Escalation

• Provide advanced technical support for complex and high-impact equipment issues.
• Support maintenance teams when routine troubleshooting does not restore equipment performance.
• Lead technical root-cause investigations for recurring or systemic equipment failures.
• Implement corrective and preventive actions to improve equipment reliability and uptime.

New Equipment & Capital Projects

• Lead equipment-related technical specifications and requirements during RFQ and supplier selection processes.
• Evaluate equipment facility requirements and ensure alignment with site standards and capabilities.
• Coordinate technical requirements with Facilities, Automation, Maintenance, Engineering teams, and external vendors.
• Support Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), installation, commissioning, and final tool acceptance.
• Coordinate equipment hook-up, installation activities, and subcontractor interactions.
• Lead equipment-related risk assessments during installation and commissioning phases.
• Ensure compliance with safety standards, quality requirements, and regulatory guidelines.
• Own equipment qualification and handover following new installations, relocations, or major upgrades.
• Transfer qualified equipment to Process Engineering and Maintenance organizations for ongoing operation and support.

ABOUT YOU

We are looking for an experienced engineer who combines strong technical expertise with a practical, hands-on approach and a passion for solving complex equipment challenges.

You have:

• A Bachelor's or Master's degree in Mechanical Engineering, Electrical Engineering, Materials Science, Physics, or a related technical discipline.
• At least 5 years of experience in equipment engineering, manufacturing engineering, or a similar technical role.
• Experience working with complex manufacturing equipment, preferably within semiconductor, microelectronics, photonics, or other advanced manufacturing environments.
• Strong troubleshooting and root-cause analysis capabilities.
• Experience supporting equipment installations, upgrades, commissioning, and qualification activities.
