About The Position

The Sr. Principal Manufacturing Engineer defines, optimizes, and sustains process integration flows across multiple manufacturing modules in a high-volume semiconductor environment. The role leads cross-module problem solving, supports product and process development, and drives improvements in yield, manufacturability, and reliability. Working with limited supervision, the engineer influences integration strategy and partners with process, equipment, and manufacturing teams to ensure integrated process performance meets product requirements.

The role supports new product introduction, pilot builds, and production ramps; helps translate R&D processes into scalable manufacturing flows; and contributes to process qualification and manufacturability assessments. It also analyzes electrical test, inline metrology, and defect data, uses structured problem-solving methods and design of experiments, and maintains integration documentation and change traceability.

Requirements

• At least 8 years of related experience with a bachelor's degree, or 6 years with a master's degree, or 3 years with a PhD, or equivalent experience.
• Experience and skills in process integration, problem analysis and solving, defect identification and analysis, defect metrology and reduction, design of experiments, and electrical characterization and measurements.
• Knowledge of 8D methodology and reporting, change management, communication, and cross-functional teamwork.
• Skills or experience associated with electroplating, etching, MES and MES integration, metrology, MEMS, optical metrology, and photolithography.

Responsibilities

• Define and refine integrated process flows across multiple manufacturing modules.
• Ensure process interactions meet product performance and reliability targets and align unit-process capabilities with integration requirements.
• Lead investigations into yield loss, defect mechanisms, and process interactions; apply data analysis and DOE methodologies to identify causes and implement corrective actions.
• Drive improvements in yield and process capability.
• Support integration for new product introduction, pilot builds, and production ramps.
• Contribute to process qualification and manufacturability assessments and help translate R&D processes into scalable manufacturing flows.
• Partner with process, equipment, yield, product, and operations teams to resolve cross-module issues.
• Support design for manufacturability and process alignment.
• Analyze electrical test, inline metrology, and defect data; execute DOEs to improve integration and resolve process interactions.
• Apply structured problem-solving methods, including DMAIC and 8D.
• Maintain integration documentation, process flows, and specifications.
• Support change control and qualification activities and ensure process changes are traceable and consistent.
