Engineer, Field Process (Phoenix, AZ)

As a member of the Global Sales and Services business unit, our HVM (High Volume Manufacturing) Field Process Engineering team serves as the on-site process application and execution bridge between the customer, ASM Field Service, ASM account leadership, and ASM global product and business-unit teams. This role supports ASM tools at our customer fab in North Phoenix with a focus on process performance, qualification execution, tool-to-tool matching, containment, escalation discipline, customer communication, and sustainable improvement.

This is not a generic process engineering role. The Field Process Engineer must be able to work close to the tool, understand customer urgency, organize incomplete data, communicate facts versus hypotheses, partner tightly with Field Service Engineers, and keep customer-facing problems moving without overclaiming root cause or creating uncontrolled risk.

What you'll be working on

Support ASM tools through installation, start-up, qualification, warranty, HVM ramp, and production-support phases
Track customer process specifications, tool performance, matching behavior, process stability, watch items, and open issue status through structured data review and follow-up
Help drive containment, short-term recovery actions, and long-term corrective actions when customer process or tool-performance requirements are not being met
Design, support, and analyze experiments for qualification, troubleshooting, continuous improvement, tool-to-tool matching, process-window understanding, and customer-requested improvements

Collect, analyze, and summarize process, metrology, tool-state, trend, and chamber-performance data to support fact-based decision-making

Apply structured troubleshooting, DOE methodologies, statistical analysis, baseline comparisons, and measurement-system validation before recommending actions

Partner with customer process teams, customer hardware teams, ASM Field Service, account leadership, and global product/business-unit experts

Communicate confirmed facts, hypotheses, action plans, ownership, timelines, and open risks clearly during urgent or ambiguous customer situations

Build clear issue timelines, data packages, passdowns, escalation payloads, and loop-closure records
Share lessons learned, BKMs, issue summaries, action plans, and watch items across the local team, key account organization, and global support teams
Maintain discipline around intellectual-property boundaries, customer communication, controlled changes, and escalation leadership

What we are looking for

Master's degree or PhD preferred in Chemical Engineering, Materials Science, Electrical Engineering, Physics, Chemistry, Mechanical Engineering, or a related technical field; Bachelor's degree candidates will be considered with significant semiconductor process, equipment, customer support, research, or HVM experience
Strong fundamentals in one or more of the following: semiconductor processing, thin films, deposition, vacuum systems, gases/pressure/flow, reaction kinetics, surface chemistry, plasma/thermal processes, metrology, or data analysis

Experience with, or a demonstrated ability to quickly learn, ALD., PEALD, epitaxy, CVD, diffusion/furnace, vacuum processing, plasma processing, or thin-film deposition

Experience designing, running, or interpreting experiments using DOE, SPC, JMP, Python, MATLAB, Excel, or equivalent tools.
