About this role
Job title: Senior Equipment Technician - EPI
About the Role Senior Equipment Technician on the EPI team responsible for the performance, reliability, and safety of ASM epitaxy systems that impact device quality and yield. You will support two ASM EPI toolsets, combining equipment expertise with process awareness to troubleshoot issues and lead escalations.
What You'll Do
- Support and maintain two ASM EPI toolsets, ensuring high availability, stability, and performance
- Perform advanced troubleshooting across mechanical, electrical, software, vacuum, thermal, and gas delivery subsystems
- Clearly document, present, and explain technical issues during tool escalations to enable effective resolution
- Apply basic process method knowledge to enhance root‑cause analysis and correlate hardware behavior with process results
- Resolve recurring alarms using standard fault trees; appropriately escalate unfamiliar or complex faults
- Lead structured root‑cause investigations using 8D, 5 Whys, and related methodologies
- Identify trends and recurring issues; implement corrective and preventive actions to reduce repeat events
- Advise on complex retrofit kits, coordinating service activities with the production plan to minimize impact
- Strictly follow safety procedures; help define work instructions and reinforce safe behaviors across the team
- Ensure compliance and support internal and external audits
- Maintain accurate service records, escalation documentation, and maintenance logs
- Mentor junior technicians, particularly in disciplined troubleshooting and structured problem solving
- Coordinate closely with escalation resources, engineering, process, and cross‑functional partners
What We're Looking For
- Technical school (2-year program), or BS with 0–1 years of experience, or 5+ years of relevant equipment experience
- Strong mechanical and electrical troubleshooting skills in a semiconductor manufacturing environment
- Experience diagnosing vacuum, thermal, and gas delivery systems
- Ability to clearly document and communicate technical issues during escalations
- Demonstrated commitment to safety, compliance, and procedural discipline
- Ability to work independently in a fast‑paced, high‑volume manufacturing environment
- Comfortable using computer‑based tools for documentation and tracking
Nice to Have
- Experience supporting ASM EPI systems or similar epitaxy platforms
- Experience working across multiple tool configurations
- Ability to integrate equipment behavior with process method understanding
- Proven use of 8D, 5 Whys, or similar structured problem‑solving methodologies
- Experience resolving recurring alarms and systemic equipment issues
- Familiarity with retrofit execution and aligning service work to production schedules
- Experience mentoring technicians and improving diagnostic standards
- Strong collaboration skills across engineering, process, and escalation teams
