• Lead root-cause investigations for process excursions, integration issues, device-performance gaps, and reliability concerns.
• Partner with Integration, Equipment Engineering, Yield, Manufacturing to resolve technical challenges.
• Define improvement strategies in yield, defectivity, process capability, reliability, manufacturability, cost, throughput, and cycle time.
• Support technology transfer from development or pilot lines into high-volume manufacturing.
• Oversee process qualification, change control, risk assessment, and production-readiness activities.
• Communicate technical results, risks, schedules, and recommendations to senior leadership.
• Promote a culture of safety, scientific rigor, innovation, collaboration, and continuous improvement.

Required Qualifications and Education:

• Master’s degree or Ph.D. in Electrical Engineering, Chemical Engineering, Materials Science, or related technical discipline.
• 5 or more years of experience in semiconductor process engineering, process integration, technology development.
• Demonstrated experience leading semiconductor technology-development programs from development through qualification, transfer, or production ramp.
• Experience managing, mentoring, or technically leading process engineering teams.
• Strong understanding of semiconductor unit processes, process integration, device performance, and manufacturing interactions.
• Experience using semiconductor process and manufacturing data to improve yield, capability, and technology performance.
• Strong project-management, communication, prioritization, and decision-making skills.
• Ability to work effectively in a cleanroom environment and support a 24/7 manufacturing operation when required.
