Equipment Engineer, Wet Process

The role

You will own a set of wet chemical tools from installation through high-volume production. You will perform hands-on repairs, diagnose failures, and manage PM schedules to maintain tool availability.

What you will do

• Own OEE, availability, MTBF, and MTTR for your toolset.
• Diagnose and restore failed components when tools go down.
• Close root cause on chronic failures, wafer breakage, and leaks using 8D, FMEA, and Pareto.
• Analyze alarm histories, maintenance records, and tool data in JMP, SQL, Python, or Excel.
• Own the PM schedule, refine vendor PM procedures, and set critical-spares levels.
• Maintain interlocks, leak detection, and exhaust and scrubber interfaces.
• Work with Process Engineering on bath life, chemical change-out, and concentration-control hardware.
• Bring tools through install, SAT, and qualification into production.
• Document procedures and train technicians.

Required qualifications

• Bachelor’s degree in Mechanical, Electrical, Chemical, or Mechatronics Engineering, or an associate degree with equivalent hands-on experience.
• 3+ years of hands-on equipment engineering in semiconductor, solar, or similar high-volume manufacturing.
• Hands-on repair of wet bench, wet etch, wet strip, or texturing tools, including pumps, valves, heaters, filtration, and wafer handling.
• Component-level troubleshooting from electrical schematics, pneumatic drawings, P&IDs, and PLC/HMI diagnostics.
• A track record of eliminating a chronic equipment failure.
• Safe working practice with hazardous chemicals, chemical-compatible materials (quartz, PVDF, PTFE, PFA), and LOTO.
• Cleanroom and sub-fab work in full chemical PPE.

Nice to have

• solar cell (TOPCon, PERC, or HJT) or semiconductor fab experience
• greenfield tool install, SAT, and ramp experience
