The Manufacturing Systems Engineer (MES / Factory Automation) supports the implementation and operation of Manufacturing Execution Systems (MES), CIM, automation, and quality systems for Amkor Technology’s advanced Arizona Technology Assembly (ATA) greenfield facility.
This role is primarily focused on system configuration, integration, and deployment rather than software development. The engineer will work closely with internal teams, vendors, and manufacturing stakeholders to build and scale highly automated, reliable factory systems from the ground up.
This is a unique opportunity to contribute to a greenfield semiconductor facility and play a key role in shaping next-generation manufacturing systems.

• Configure, test, and support MES and related manufacturing systems
• Integrate MES with CIM/EAP, automation systems (AMHS/OHT), quality systems, and enterprise platforms (ERP)
• Manage system interfaces and data flows (lot tracking, WIP, recipes, dispatching logic)
• Maintain manufacturing master data (process flows, equipment, materials, recipes)
• Troubleshoot system issues impacting manufacturing operations and data integrity
• Collaborate with vendors (e.g., AMAT) and cross-functional teams (manufacturing, quality, IT, automation)
• Participate in system design reviews and requirement definition
• Document system functionality, enhancements, and procedures
• Bachelor’s degree in Engineering, Computer Science, Information Systems, or a related discipline
• 3–6 years of experience in manufacturing IT, factory automation, or semiconductor manufacturing systems
• Hands-on experience with MES, CIM/EAP/RMS, automation, logistics, or quality systems (SPC, FDC)
• Understanding of semiconductor manufacturing processes and shop floor operations
• Experience supporting production manufacturing systems
• Strong communication skills and ability to work in cross-functional teams

• Experience with commercial manufacturing software platforms (Applied Materials preferred)
• Experience supporting MES or automation systems in a semiconductor fab, assembly, or test site
• Exposure to system integration or factory system rollout projects
• Basic understanding of equipment interfaces or material handling systems
• Familiarity with analytics or AI/ML use cases in manufacturing

Additional Information

• This role is focused on project implementation and factory ramp-up, not steady-state support
• Limited coding required; emphasis is on configuration, integration, and troubleshooting
• Opportunity for a mix of desk-based and factory floor interaction depending on assignment
• Ability to travel internationally (e.g., Korea) for training as needed

Why Amkor

• Be part of a greenfield semiconductor facility and help build systems from the ground up
• Work with advanced manufacturing technologies in a high-growth environment
• Gain hands‑on experience with cutting‑edge MES and automation systems
• Collaborate with global teams and industry‑leading partners

Location

This position will be based at the temporary Phoenix, AZ site and the Peoria site during the construction phase, and will transition to the Peoria site once factory operations begin.
