Equipment Engineer, Thermal

The role

You will own a set of thermal tools including boron diffusion and oxidation vertical tube furnaces and Boating Room equipment. You will manage tool availability, perform hands-on repairs, and develop maintenance procedures for a new solar cell fab.

What you will do

• Own OEE, availability, MTBF, and MTTR for the toolset.
• Diagnose and restore failed components on tools.
• 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 and set critical-spares levels.
• Maintain interlocks, gas detection, exhaust, scrubber interfaces, and over-temperature protection.
• Work with Process Engineering on quartzware life, boat load and unload hardware, and temperature profiling.
• Bring tools through install, SAT, and qualification into production.
• Write 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 tube diffusion, oxidation, or LPCVD furnaces, including heating elements, thermocouples, gas delivery, vacuum and pressure control, and boat handling.
• Component-level troubleshooting from electrical schematics, pneumatic drawings, P&IDs, and PLC/HMI diagnostics.
• Track record of eliminating a chronic equipment failure.
• Safe working practice with toxic and corrosive process gases, high-temperature systems, quartzware handling, and LOTO.
• Ability to work in cleanroom and sub-fab in full chemical PPE.

Nice to have

• Solar cell (TOPCon, PERC, or HJT) or semiconductor fab experience.
• Greenfield tool install, SAT, and ramp experience.
