Sr. Field Service Engineer IV

Job Description: Senior Field Service Engineer IV (AZ / Dual-Platform Lead)

Location: Phoenix, AZ

Shift / Travel: Local Fab Support (Phoenix, AZ Area) with On-Call Rotation & Limited Overseas/Domestic Travel

Position Overview

The Senior Field Service Engineer IV (FSE IV) serves as a lead technical expert responsible for tool installation, startup, advanced troubleshooting, preventive maintenance, and modifications for advanced semiconductor capital equipment. In this high-visibility role supporting our Strategic OEM Partnership, the FSE IV will provide critical on-site support at a leading-edge semiconductor manufacturing facility in Arizona across both strategic partner wet processing product lines (Wet Etch / Clean platforms) and Plasma-Therm plasma processing equipment (e.g., PECVD and Dry Etch systems).

The ideal candidate brings deep technical expertise in chemical dispense delivery, wet processing mechanics, fluidics, high-purity piping, process temperature control, vacuum systems, and robotics, along with strong customer-facing leadership skills to manage complex fab escalations.

Key Responsibilities

1. Overseas OEM Training & Product Bring-Up

• Complete intensive, hands-on factory training at the strategic partner’s manufacturing facility in Taiwan on new pre-release wet processing/wet etch platforms.
• Work directly with factory development engineers during sub-assembly, software configuration, and initial tool integration.
• Help capture, review, and refine initial standard operating procedures (SOPs), maintenance protocols, and commissioning checklists for field deployment.

2. Tool Move-In, Installation & Commissioning

• Lead and oversee on-site tool uncrating, rigging supervision, facility chemical/utility hookup verification, and system power-on for new tool deliveries in Phoenix.
• Execute pre-commissioning checks, sensor calibrations, fluid delivery testing, and Site Acceptance Testing (SAT) to achieve fast time-to-first-wafer.
• Interface directly with customer fab engineers, facility chemical engineering teams, and rigging contractors to maintain installation schedules.

3. Advanced Technical Troubleshooting & Dual-Platform Support

• Perform routine preventive maintenance (PM) and unscheduled corrective maintenance across both wet etch systems and Plasma-Therm dry processing platforms      under strict SLA guidelines (<2 hour response target).
• Lead root-cause failure analysis for complex chemical delivery, fluidic valves, heater control, robotic wafer transfer, vacuum, and electromechanical escalations.
• Author and drive 8D Quality/Failure Reports to closure in collaboration with factory engineering teams in Taiwan and domestic headquarters.

4. Customer Account & Escalation Management

• Serve as the primary technical point of contact during critical tool-down scenarios, conducting daily technical updates with customer fab management.
• Ensure strict adherence to customer safety (EHS), cleanroom, chemical handling, and Lockout/Tagout (LOTO) protocols.
• Mentor and train peer engineers, supporting the development of internal SOPs and training logs.
