At Western Digital, our vision is to power global innovation and push the boundaries of technology to make what you thought was once impossible, possible.

At our core, Western Digital is a company of problem solvers. People achieve extraordinary things given the right technology. For decades, we've been doing just thatour technology helped people put a man on the moon and capture the first-ever picture of a black hole.

We offer an expansive portfolio of technologies, HDDs, and platforms for business, creative professionals, and consumers alike under our Western Digital, WD, and WD_BLACK.

We are a key partner to some of the largest and highest-growth organizations in the world. From enabling systems to make cities safer and more connected, to powering the data centers behind many of the world's biggest companies and hyperscale cloud providers, to meeting the massive and ever-growing data storage needs of the AI era, Western Digital is fueling a brighter, smarter future.

The role involves leading TOFSIMS analysis to characterize thin films and surfaces, developing and validating analytical methods to support manufacturing and quality programs, and interpreting mass spectra for insights into process improvements. It includes supporting failure analysis, collaborating with cross-functional teams to apply findings, maintaining and troubleshooting TOFSIMS equipment, and training junior engineers and technicians. Additionally, it entails driving continuous improvements in analytical capabilities, preparing technical reports, and ensuring compliance with safety and quality standards in all operations.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

• Lead TOFSIMS analysis to characterize thin films, surfaces, interfaces, and contamination for media products.
• Develop, optimize, and validate TOFSIMS analytical methods to support manufacturing, quality, and development programs.
• Interpret complex mass spectra and depth profiles to provide actionable insights for process and material improvements.
• Support failure analysis and rootcause investigations for yield loss, reliability issues, and process excursions.
• Collaborate with crossfunctional teams (Process, R&D, Quality, Reliability) to translate analytical findings into engineering solutions.
• Maintain and troubleshoot TOFSIMS equipment to ensure high uptime, accuracy, and calibration integrity.
• Train junior engineers, technicians, and crossfunctional partners on TOFSIMS fundamentals, sample preparation, and data interpretation.
• Lead continuous improvement initiatives to enhance analytical capability, throughput, and data quality.
• Prepare technical reports, documentation, and presentations for internal stakeholders and global engineering teams.
• Ensure compliance with safety, quality, and dataintegrity standards in all analytical operations.
  
  

REQUIRED:

Bachelor's or Master's degree in Materials Science, Chemistry, Physics, Chemical Engineering, or related field.

PREFERRED:
