Sr Principal Integration and Yield Engineer

Overview

Forming Our Future together Form Factor, Inc. (NASDAQ: FORM), is a leading provider of essential test and measurement technologies along the full semiconductor product life cycle — from characterization, modeling, reliability, and design de-bug, to qualification and production test. Semiconductor companies rely upon Form Factor’s products and services to accelerate profitability by optimizing device performance and advancing yield knowledge. The company serves customers through its network of facilities in Asia, Europe, and North America.

The regular hours for this position are day shift.

We are seeking a highly skilled, hands-on Sr. Principal Integration & Yield Engineer to join our Production Engineering team. This role is critical in driving end-to-end process integration, yield improvement, and defect reduction for a unique semiconductor application.

You will act as a technical leader within the fab environment—owning complex yield challenges, leading data-driven problem-solving efforts, and influencing cross-functional teams. The ideal candidate brings deep semiconductor process expertise, strong analytical capability, and a proven track record of solving high-impact manufacturing problems.

• Lead process integration strategy across the full process flow, ensuring seamless interaction of unit processes into robust, high-yielding module flows.
• Own and drive yield improvement initiatives, identifying key yield limiters and implementing sustainable solutions.
• Use structured problem-solving methodologies (e.g., 8D, DMAIC, root cause analysis) to resolve yield excursions using inline data, electrical test data, failure analysis, and direct fab observations.
• Analyze and interpret data from defect inspection and metrology tools to identify, characterize, and eliminate yield-limiting defects.
• Partner with process engineering teams to optimize process windows, improve uniformity, and enhance overall device performance.
• Lead design of experiments (DOE) and leverage statistical process control (SPC) and advanced analytics to drive continuous process improvement.
• Serve as a cross-functional technical leader, collaborating with fab operations, equipment engineering, test, and R&D to implement and validate process changes.
• Own flying probe electrical test processes, including data analysis, reporting, and automation of test outputs.
• Monitor rework trends and scrap drivers, implementing process improvements to reduce rework rates and improve cycle time.
• Support technology transfer and ramp from R&D into high-volume manufacturing, ensuring stable yield and manufacturability.
• Develop and maintain process integration documentation, including flows, specs, and control strategies.
• Lead and mentor cross-functional teams in data-driven problem solving and best practices.

• Experience with advanced analytics tools or scripting (e.g., JMP, Python, MATLAB)
• Familiarity with electrical test systems, including flying probe or wafer sort methodologies
• Experience supporting new product introduction (NPI) and manufacturing ramp.
• Knowledge of yield modeling, reliability analysis, and failure analysis techniques.
• Proven experience solving complex yield and defectivity challenges in a high-volume fab environment.
• Deep understanding of semiconductor unit processes (e.g., lithography, etch, deposition, CMP) and their interactions.
• Strong expertise in data analysis, DOE, and SPC methodologies.
• Hands-on experience with defect inspection and metrology tools.
• Demonstrated ability to lead cross-functional technical teams and influence without authority.
• Strong problem-solving, communication, and documentation skills.
