Manufacturing Quality Engineer

Description

SUMMARY

The Manufacturing Quality Engineer is responsible for establishing and enforcing global manufacturing quality control systems across all production sites. This role focuses on defining quality governance, Critical-to-Quality (CTQ) parameters, and standardized inspection systems to ensure consistent and predictable product quality. The position owns the design and deployment of global quality rules, including inspection criteria across Process Quality Control (PQC), Final Quality Control (FQC), and Outgoing and Reliability Quality Control (OQC), as well as sampling strategies and decision standards to prevent defect leakage.

It drives data-based quality management by integrating process, inspection, and equipment data to enable real-time monitoring and early detection of abnormalities. The role also leads the implementation of abnormality detection and escalation systems, ensuring rapid containment, structured root cause analysis, and effective recurrence prevention. This role establishes and maintains global quality standards, including electrical performance verification and visual/appearance inspection standards (e.g., EL imaging-based defect inspection and appearance criteria), aligned with customer and certification requirements.

In addition, the position conducts cross-site audits and enforces compliance with defined standards, identifying execution gaps and driving corrective actions. It manages manufacturing quality risks across the full value chain (Ingot, Wafer, Cell, Module) by defining preventive controls and CTQs to mitigate upstream-to-downstream impacts. The role collaborates with global manufacturing sites to ensure alignment, standardization, and deployment of best practices, ultimately strengthening overall manufacturing quality competitiveness and ensuring stable product quality output.

RESPONSIBILITIES

• Quality Governance & Control Framework :
  Define and enforce global manufacturing quality governance by establishing CTQ-based control frameworks, inspection criteria (PQC/FQC/OQC), and standardized decision rules to ensure consistent quality across all sites.
• CTQ-Based Process Quality Management :
  Identify and deploy Critical-to-Quality (CTQ) parameters across IWCM processes based on QMP, field data, and process risk analysis. Monitor process capability (Cpk/Ppk) and drive early detection of abnormal trends.
• Inspection System Ownership (Gatekeeper Role) :
  Own and standardize global inspection systems including criteria, sampling logic, and detection capability. Ensure outgoing quality is controlled through robust FQC/OQC gatekeeping and prevent defect leakage.
• Abnormality Detection & Escalation System :
  Design and operate data-driven abnormality detection systems (e.g., MES/QIS) with defined thresholds and escalation rules. Ensure rapid containment, root cause analysis, and horizontal deployment of corrective actions.
• Quality Standards & Rule Management :
  Establish, maintain, and continuously upgrade global quality standards (EL, OSC, electrical performance, etc.). Eliminate ambiguity in acceptance/rejection criteria and ensure alignment with customer and certification requirements.
• Process Audit & Compliance Enforcement :
  Lead cross-site process audits and theme-based assessments to verify adherence to defined standards. Enforce compliance through structured evaluation, escalation, and corrective action tracking.
• Manufacturing Risk Management :
  Analyze inter-process risks across Ingot, Wafer, Cell, and Module operations. Define preventive controls and CTQs to mitigate upstream-to-downstream quality impacts.
• Quality Data Integration & Monitoring :
  Define and standardize quality data structures across systems (MES, equipment, inspection). Ensure data integrity and enable real-time monitoring for decision-making and risk prediction.
• Supplier & Incoming Quality Control Strategy :
  Define IQC control strategies and supplier quality requirements based on risk level. Ensure incoming material quality is systematically controlled and aligned with manufacturing requirements.
• Cross-Site Alignment & Best Practice Deployment :
  Drive alignment of quality practices across global…
