Job Summary

Lumentum is seeking a Night Shift Equipment Maintenance Technician to support 24/7 manufacturing of advanced photonic and optoelectronic devices. This role is responsible for sustaining lithography and vacuum-based semiconductor processing equipment used in the fabrication of lasers, optical components, and III-V devices. The technician will perform hands-on troubleshooting, maintenance, and real-time production support to ensure high equipment uptime, process stability, and product quality during overnight operations.

Key Responsibilities

Equipment Monitoring & Troubleshooting

• Monitor and maintain performance of lithography and vacuum-based processing equipment, including:
  • Steppers, mask aligners, coat/develop tracks
  • Vacuum chambers and pumping systems (dry pumps, turbomolecular pumps, forelines)
• Rapidly diagnose and resolve equipment faults, alarms, vacuum leaks, and process deviations.
• Perform safe and efficient tool recoveries to return equipment to production.

Vacuum Systems Support

• Maintain and troubleshoot high and ultra-high vacuum (HV/UHV) systems used in semiconductor processing.
• Diagnose issues related to:
  • Vacuum integrity (leaks, pressure instability)
  • Pump performance (mechanical, turbo, cryo where applicable)
  • Valves, gauges, mass flow, and gas delivery systems
• Perform pump swaps, rebuild coordination, and chamber conditioning as required.
• Support vacuum system calibration and ensure compliance with process specifications.

Preventive & Corrective Maintenance

• Execute scheduled PMs on lithography and vacuum equipment to ensure reliability and precision.
• Perform corrective maintenance including:
  • Component replacement (seals, O-rings, pumps, sensors)
  • System calibration and alignment
  • Cleaning and rebuild activities for vacuum chambers
• Update and improve maintenance procedures where applicable.

Production Support

• Support manufacturing operations to maintain continuous production of photonic devices.
• Escalate complex equipment or vacuum-related issues with detailed documentation.

Lithography & Process Support

• Assist in controlling critical lithography parameters:
  • Critical dimension (CD) uniformity
  • Overlay/alignment accuracy
  • Defectivity reduction
• Ensure stable resist processing and exposure conditions within controlled vacuum/cleanroom environments where applicable.

Data Collection & Shift Communication

• Log equipment performance, downtime events, and maintenance activities.
• Provide comprehensive shift handoff reports detailing tool status and open issues.
• Support engineering teams with data collection for root cause analysis.

Continuous Improvement

• Identify opportunities to improve equipment reliability, vacuum performance, and uptime.
• Participate in improvement projects related to:
  • Vacuum system stability
  • Tool availability and throughput
• Recommend enhancements to spare parts strategies and PM schedules.

Required Qualifications

• Associate degree or technical certification in Electronics, Mechanical Engineering Technology, Mechatronics, or related field (or equivalent experience).
• 2+ years of experience in semiconductor, photonics, or precision manufacturing.
• Hands-on troubleshooting experience with complex manufacturing equipment.
• Working knowledge of:
  • Mechanical, electrical, pneumatic systems
  • Vacuum systems and gas handling fundamentals
• Willingness to work a permanent night shift schedule (including weekends/holidays).

Preferred Qualifications

• Experience with lithography equipment (ASML, Canon, Nikon, SUSS, TEL tracks).
• Experience supporting vacuum-based semiconductor tools (e.g., deposition, etch, implant).
• Familiarity with high vacuum (HV/UHV) systems, leak detection techniques, and pump technologies.
• Exposure to III-V or photonics manufacturing (InP, GaAs, lasers, optical components).
• Ability to read schematics, P&IDs, and vacuum system diagrams.
• Experience with automation, robotics, or PLC systems.
• Basic data analysis skills (Excel, JMP).

Key Skills & Competencies

• Strong troubleshooting skills in both lithography equipment and vacuum systems
• Ability to work independently during off-shift hours
• High sense of urgency and ownership in a production environment
• Detail-oriented with strict adherence to procedures and cleanliness standards
• Clear communication for shift handoffs and escalation

Work Environment

• Semiconductor cleanroom environment supporting photonics manufacturing
• Frequent interaction with vacuum systems, gas lines, and precision optical equipment
• Strict adherence to contamination control and EHS standards
• Physically active role (standing, lifting, working on equipment)
• Night shift schedule (10–12 hour shifts; compressed workweek possible)
• Shift differential and overtime opportunities

Salary Range
The salary range for this position is $70,000 – 90,000USD.

Final compensation will be determined based on factors such as experience, skills, and qualifications.
