Job Requirements
We are seeking a Data Scientist with 5+ years of experience to develop machine learning solutions for failure prediction, classification, and fault analysis in semiconductor manufacturing and equipment systems. This role focuses on time-series modeling, equipment health monitoring, and root-cause analysis using structured reliability methods such as fault tree analysis (FTA).
You will work with complex, high-volume data from semiconductor tools (sensor signals, logs, process data) to improve tool uptime, yield, and operational reliability.
-
Design, develop, and deploy machine learning models for equipment failure prediction and fault classification
-
Analyze time-series data from semiconductor tools (sensor telemetry, logs, process traces)
-
Perform advanced feature engineering (lags, rolling windows, trends, seasonality, event-based features)
-
Apply fault tree analysis (FTA) concepts to support root-cause analysis and improve model interpretability
-
Collaborate with process engineers, equipment engineers, and failure analysis teams
-
Select, justify, and evaluate appropriate ML algorithms
-
Validate models using metrics such as precision/recall, F1-score, ROC-AUC, and early failure detection accuracy
-
Document models, assumptions, and results for technical and cross-functional stakeholders
-
Mentor junior data scientists and contribute to best practices
