Field Process Engineer (Phoenix, AZ)

About the role

As a Field Process Engineer, you will work closely with customers and equipment to resolve process and tool performance challenges. This role requires strong technical judgment, structured problem-solving, clear communication, and the ability to drive customer issues to resolution while distinguishing facts from hypotheses and minimizing operational risk.

Responsibilities

• Support ASM tools through installation, startup, qualification, warranty, high-volume manufacturing (HVM) ramp, and production phases.
• Monitor process performance, tool matching, stability, and open issues through structured data analysis and follow-up.
• Drive containment, recovery, and corrective actions when process or tool performance targets are not met.
• Design, execute, and analyze experiments to support qualification, troubleshooting, process optimization, tool matching, and customer-requested improvements.
• Collect and interpret process, metrology, equipment, and performance data to support fact-based decision making.
• Apply structured troubleshooting, DOE methodologies, statistical analysis, and measurement-system validation to identify and resolve issues.
• Partner with customer engineering teams, ASM Field Service Engineers, account teams, and global subject matter experts to resolve technical challenges.
• Clearly communicate findings, action plans, risks, ownership, and timelines during routine and escalated customer situations.
• Develop issue timelines, technical reports, escalation packages, passdowns, and closure documentation.
• Share best practices, lessons learned, and key updates across local, account, and global support teams.
• Maintain compliance with intellectual property requirements, controlled change processes, and customer communication guidelines.

Requirements

• 6+ years of semiconductor equipment experience or equivalent hands-on technical experience.
• Experience supporting semiconductor capital equipment in HVM, customer support, process development, applications engineering, or field support environments.
• Demonstrated success supporting customer escalations, qualification activities, process transfers, tool matching, scale-up efforts, or continuous improvement projects.
• Strong troubleshooting and problem-solving skills at the system and process level.
• Experience working in customer-facing and cross-functional environments.
• Ability to effectively collaborate with Field Service Engineers, customer engineers, account teams, and global technical experts while maintaining ownership and accountability.
• Comfortable working in fast-paced environments with incomplete information while avoiding unsupported root-cause conclusions or uncontrolled process changes.
• Strong documentation, communication, and organizational skills.
• Experience using data analysis tools such as Excel, JMP, Python, MATLAB, or similar platforms.
• Knowledge of semiconductor manufacturing processes and fab operations.
• Experience supporting global customers and/or high-volume manufacturing environments.
• Experience with CMP, polishing, or related wafer processing equipment preferred.
• Ability to travel internationally as required.
• Flexibility to support extended hours, weekends, or additional fab time during qualifications, escalations, and critical customer events.

Qualifications

• Bachelor's degree in Chemical Engineering, Materials Science, Electrical Engineering, Physics, Chemistry, Mechanical Engineering, or a related technical field.
• Strong foundation in one or more of the following areas:
  • Semiconductor processing
  • Thin films and deposition
  • Vacuum systems
  • Gas, pressure, and flow control
  • Reaction kinetics and surface chemistry
  • Plasma or thermal processes
  • Metrology and data analysis
• Experience with, or the ability to quickly learn, CMP processes and applications.
• Experienced candidates should demonstrate increasing levels of ownership, technical leadership, customer engagement, mentoring, and the ability to lead complex troubleshooting and qualification activities across cross-functional teams.
