Company Overview

Our client is a leading Korean semiconductor equipment company providing advanced manufacturing, automation, and test solutions to major semiconductor manufacturers worldwide. 

To strengthen its customer support capability in Taiwan, the company is seeking an experienced Field Service Engineer to support wafer probers and related semiconductor test equipment at customer sites. 

This role will work closely with a Korea-based manager and headquarters engineering teams while serving as a key local technical contact for customers in Taiwan. As the Taiwan business expands, the position may offer opportunities to take on broader customer, technical, and organizational responsibilities. 

Job Summary

The Field Service Engineer will be responsible for the onsite installation, maintenance, troubleshooting, and technical support of wafer probers and related semiconductor back-end test equipment in Taiwan. 

This is an independent, customer-facing role requiring strong hands-on equipment experience, sound technical judgment, and the ability to manage customer issues with limited local supervision. 

The successful candidate will communicate directly with customer engineering teams, provide timely equipment support, and coordinate with Korea headquarters to resolve complex technical issues. The role requires fluent Mandarin, Korean communication capability, regular customer-site travel, and flexibility to support fab schedules when necessary. 

Responsibilities

• Provide onsite technical support for wafer probers and related semiconductor test equipment at customer fabs.  

• Perform equipment installation, setup, calibration, qualification, and customer acceptance activities.  

• Conduct preventive maintenance and corrective maintenance to minimize equipment downtime.  

• Diagnose and resolve equipment issues involving mechanical systems, electrical systems, equipment software, motion control, pneumatics, sensors, servo systems, vacuum systems, and automation components.  

• Support equipment readiness and issue resolution during installation, qualification, and production ramp-up.  

• Communicate directly with customers regarding equipment condition, downtime, recovery progress, action plans, and technical issues.  

• Manage assigned customer issues independently and ensure timely follow-up and ownership.  

• Work closely with Korea headquarters engineering and service teams to troubleshoot and resolve complex technical problems.  

• Escalate unresolved issues with clear technical information, troubleshooting history, and appropriate judgment.  

• Prepare service reports, maintenance records, troubleshooting documents, and issue-escalation reports.  

• Support spare-parts management and service schedule planning.  

• Provide basic equipment operation or maintenance training to customers when required.  

• Respond to customer inquiries by phone or email during working hours.  

• Support occasional on-call or weekend service activities based on customer fab schedules.  

• Attend technical training in Korea for approximately one to two months when required.  

Requirements

• Diploma or Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Electronics Engineering, Automation, Mechatronics, or a related discipline.  

• At least five years of semiconductor equipment service, equipment engineering, maintenance, or technical-support experience.  

• Hands-on experience working with semiconductor manufacturing equipment.  

• Cleanroom and customer-fab working experience.  

• Strong troubleshooting capability across mechanical, electrical, pneumatic, sensor, motor, motion-control, servo, vacuum, automation, or equipment-software systems.  

• Experience performing equipment installation, preventive maintenance, corrective maintenance, calibration, and issue resolution.  

• Ability to work independently and manage customer-site issues with strong ownership.  

• Mature customer communication skills and the ability to respond appropriately in urgent or high-pressure situations.  

• Fluent Mandarin for customer-site communication.  

• Korean communication ability for reporting to the Korea-based manager and headquarters.  

• Intermediate English ability for technical documents and cross-border communication.  

• Must hold a valid driver’s license and have access to a vehicle for customer-site support.  

• Ability to travel domestically approximately one to two times per week.  

• Ability to support customer production schedules, including occasional weekend or on-call requirements.  

Preferred Qualifications

• Experience supporting wafer probers, probe stations, test handlers, memory-test equipment, package-test equipment, or related semiconductor back-end systems.  

• Experience working for a semiconductor test-equipment or probe-station vendor.  

• Experience supporting equipment teams within memory, foundry, or OSAT environments.  

• Familiarity with memory-device testing and wafer-level test processes.  

• Experience supporting major semiconductor customers in Taiwan.  

• Familiarity with equipment acceptance, qualification, production ramp-up, and downtime-recovery processes.  

• Experience working with Korean headquarters or Korean engineering organizations.  

• Ability to read and prepare technical documents in Korean, Mandarin, and English.
