About the Job

Requirements

  • A bachelor's degree in engineering or a related field is required; mechanical or electrical engineering is preferred.
  • At least 5 years of field service engineering experience is required.
  • Native or near-native proficiency in Mandarin Chinese and English, including reading, writing, and speaking, is required.
  • The engineer must be able to work in a cleanroom environment.

Responsibilities

  • Install and maintain semiconductor manufacturing equipment, including photolithography, chemical vapor deposition, physical vapor deposition, etch, diffusion, implant, wirebond, flip-chip, die-attach, molding, and testing tools.
  • Complete a 6- to 18-month intensive on-the-job training program in Miyagi, Japan.
  • Participate in international business travel and global project deployments after training.
  • Document workflows and implement standard operating procedures to optimize processes.
  • Maintain radio-frequency generators, vacuum pumps, and gas delivery systems to ensure high uptime for plasma etch reactors.
  • Diagnose and repair complex electromechanical and pneumatic systems.
  • Optimize chamber-cleaning procedures and preventive-maintenance schedules to control selectivity and profile.
  • Troubleshoot laser systems, optical alignments, robotics, and high-precision stages.
  • Develop, implement, and optimize preventive-maintenance programs to achieve equipment availability targets above 90–95% and reduce mean time between failures.
  • Manage installation and operational qualification of new capital equipment, collaborating with vendors and process engineering teams.
  • Ensure maintenance and operating procedures adhere to environmental, health, and safety regulations and cleanroom protocols.
  • Translate documents, emails, tickets, and presentations between Mandarin and English, and provide real-time interpretation during meetings and calls.
  • Facilitate communication between departments, including research and development, operations, and customer service, to support project alignment.
  • Handle inquiries, disputes, and service requests from Mandarin-speaking customers by phone, email, or chat.
  • Identify communication gaps and suggest improvements to support quality assurance.
  • Fine-tune photolithography, etch, chemical vapor deposition, physical vapor deposition, atomic layer deposition, diffusion, and implant processes to improve semiconductor-device yield, efficiency, and performance.
  • Identify causes of process deviations, defects, and yield issues, and implement corrective actions in a high-volume manufacturing environment.
  • Develop recipes for plasma etch systems to meet profile and selectivity specifications.
  • Ensure critical dimensions are maintained after processing.
  • Oversee installation, calibration, corrective maintenance, and preventive maintenance of photolithography, etch, chemical vapor deposition, physical vapor deposition, atomic layer deposition, diffusion, and implant equipment, including steppers, scanners, track systems, and metrology tools.
