Experienced eSPEC System Engineer

The company is looking for an engineer to own and operate the fab-critical eSPEC application, the centralized repository of process, limit, recipe, overlay and defect specifications. The engineer works across the entire Software Testing Life Cycle to ensure any system change is introduced without disrupting the 24×7 manufacturing environment. As subject-matter expert, the role covers UI maintenance, back-end data integration, process-improvement initiatives, routine maintenance and deep-dive troubleshooting. The position partners closely with fab engineering, MES teams and the Korean development counterpart to keep the application and its database in sync, drive migrations and upgrades, and improve performance while preserving reliability for high-volume semiconductor production.
