The engineer will also help maintain and monitor AOI's existing fab process dashboard and work closely with Process Integration, Yield Engineering, Fab, Equipment Engineering, Quality, Reliability, and IT teams.
Responsibilities - Develop Python scripts for data collection, cleaning, reduction, analysis, visualization, and automated reporting.
- Build and maintain databases that integrate fab process, equipment, metrology, device-test, yield, and reliability data.
- Establish data traceability across product, lot, wafer, process step, tool, recipe, operator, and timestamp.
- Develop automated JMP workflows, scripts, reports, and visualization tools for manufacturing-data analysis.
- Create and maintain dashboards, wafer maps, trend charts, and automated reports for engineering and production teams.
- Maintain and monitor the existing fab process dashboard.
- Troubleshoot dashboard, data-connection, and data-integrity issues in collaboration with Equipment Engineering and IT.
- Develop automated alerts that help process and yield engineers identify process shifts, equipment abnormalities, and manufacturing excursions.
- Provide reliable datasets and analytical workflows to support SPC, process capability, DOE, correlation, reliability, and root-cause analyses.
- Work with yield engineers and process owners to translate analytical requirements into scalable databases, scripts, dashboards, and reports.
- Establish data-validation rules and monitor the accuracy, completeness, and consistency of manufacturing data.
- Document databases, scripts, dashboards, interfaces, and standard analysis methods.
Qualifications - Bachelor's degree in Data Science, Computer Science, Engineering, Statistics, Physics, Mathematics, or a related technical field.
- 3 or more years of experience in data engineering, manufacturing analytics, database development, scientific software, or equipment-data automation.
- Strong Python programming skills, particularly for data processing, automation, analysis, and visualization.
- Strong working knowledge of JMP for statistical analysis, visualization, and preferably JMP Scripting Language.
- Experience with SQL, relational databases, database design, and combining data from multiple sources.
- Working knowledge of manufacturing statistics, including SPC, process capability, regression, ANOVA, DOE, and measurement-system analysis.
- Ability to clean, reduce, analyze, and manage large manufacturing datasets.
- Familiarity with LabVIEW and the ability to maintain and troubleshoot an existing LabVIEW-based dashboard.
- Ability to communicate effectively with engineering, manufacturing, quality, reliability, and IT teams.
Preferred Qualifications - Master's degree in Data Science, Computer Science, Engineering, Statistics, or a related technical field.
- Experience in semiconductor fabrication, optoelectronics, photonics, or another high-volume manufacturing environment.
- Experience with Python libraries such as pandas, NumPy, SciPy, matplotlib, seaborn, or Plotly.
- Experience analyzing wafer maps, equipment histories, metrology results, product-test data, reliability data, or manufacturing yield.
- Experience developing automated reports, process-monitoring alerts, and interactive dashboards.
- Familiarity with manufacturing execution systems, equipment databases, SPC systems, or quality-management systems.
- Experience with REST APIs, Git, Linux, or software version-control practices.
Key Competencies - Strong Python, SQL, JMP, and data-management capability.
- Good understanding of database structure and manufacturing-data traceability.
- Working knowledge of manufacturing statistics and data visualization.
- Strong data-quality and troubleshooting skills.
- Ability to understand manufacturing requirements and convert them into practical data solutions.
- Effective cross-functional collaboration.
- Clear technical communication and documentation.
Location This position will be on-site based in Sugar Land, Texas.
