Responsibilities
Own inline  defect density performance  (e.g., particles/defects per wafer or per cm²) and drive reductions to meet yield, quality, and customer targets.
Operate and optimize  defect inspection  across tools (optical brightfield/darkfield, patterned wafer inspection) including recipe tuning, nuisance reduction, and tool-to-tool matching.
Define and execute  defect monitoring strategy :
Lot/monitor wafer plan, inspection points (pre/post critical steps), sampling rates, and sensitivity/recipe settings.
Perform  defect disposition and classification : nuisance vs real defects, systematic vs random; maintain defect library and automate classification where applicable.
Lead  defect excursion management : rapid detection, lot containment (hold/quarantine), risk assessment, and communication with Production/QA/Yield.
Drive  adder control  by step/tool/module: quantify adders (after–before), identify top contributing tools/recipes/chambers, and lead corrective actions.
Execute  root-cause analysis (RCA)  using defect maps, signature analysis, cluster/hotspot detection, equipment logs, PM history, chemical/consumable lots, and wafer transport/FOUP history
Coordinate  defect review and failure analysis : SEM review, EDS, FIB cross-section requests; correlate physical defects to electrical impact with Yield/Product teams.
Own defect density and D0 performance; quantify defect-to-yield loss using kill ratio, CP/WAT correlation, and yield loss prediction models.
Lead DSA and manage the defect library/classification (real vs nuisance); drive nuisance filtering and review/BKM standardization.
Develop and optimize inspection recipes (sensitivity/threshold/care-area), tool matching, and post-PM qualification to control adders and excursions.
Drive defect reduction CIP:
Pareto top contributors, RCA with module/equipment/CFM/yield teams, and implement CAPA for sustained improvement
Support new inspection tool installs, tech transfer, and ramp by completing tool qualification and production release, defining acceptance criteria, and ensuring sustainable capacity and uptime.
Mentor more Engineers as required
Travel, as necessary
Presentation to internal teams and senior executives
Drive cross-functional yield improvement projects and DOEs
Apply structured problem-solving and risk tools: FMEA, 8D, and strong RCA to drive effective corrective action and prevent recurrence
Ensure inspection measurement capability/accuracy via basic MSA/GR&R and tool-to-tool correlation
Use SPC, FDC, and APC to monitor process health, detect excursions early, and enable data-driven defect/yield control

Essential Attributes
Able to work independently, self-motivated with a strong drive to win.
Team player with the ability to work across diverse cross-functional teams spread across the world.
Leadership skills to influence all levels of the organization.
You’re inclusive, adapting your style to the situation and diverse global norms of our people.
An avid learner, you approach challenges with curiosity and resilience, seeking data to help build understanding.
You’re collaborative, building relationships, humbly offering support and openly welcoming approaches.
Innovative and creative, you proactively explore new ideas and adapt quickly to change.
