• Serve as a secondary owner for one additional process module (lithography, PVD, etch, ECD, CVD, or ALD), providing backup support and operational expertise.
• Cross‑train and operate tools across other modules of the micro/nano‑fabrication line as needed.
• Run product wafers through the fabrication line, owning one or more process modules and related metrology operations, flagging quality control issues to line and integration owners.
• Conduct data analysis and leverage statistical tools to monitor and enhance process performance.
• Maintain a high standard of lab safety and contribute to fostering a culture of safety excellence within cleanroom environments.
• Collaborate with diverse teams and internal partners to ensure efficient operation and continuous improvement.
• Follow Business Technology policies to protect sensitive data and reduce information security occurrences.

• Bachelor's Degree in Physics, Electrical Engineering, Materials Science, or equivalent required
• Minimum of 3 years in semiconductor processing, metrology, device characterization, and/or semiconductor packaging required.
• Proven experience in tool ownership for semiconductor fabrication equipment.
• Expertise in at least one semiconductor process module (lithography, PVD, etch, ECD, CVD, or ALD).
• Strong understanding of semiconductor‑related materials, processing, integration, devices, and/or testing.
• Experience with data analysis and statistical tools.
• Strong sense of intellectual honesty, attention to detail, and excellent communication and organizational skills.
• Ability to work independently and in a team environment.
• ITAR - Permanent resident of the United States (“U.S. person” as defined by ITAR)
