To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale—faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.

Group/Division

The Semiconductor Products and Customers (Semi PC) business unit designs, builds and sells KLA’s product portfolio to help chip manufacturers meet high-quality standards for technologies like AI, data centers, automotive and electronic devices. Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics. The e-Beam division plays a critical role in KLA’s inspection ecosystem, with tools that deliver high-resolution, timely insights into defects and critical locations on the wafer. Used alongside KLA’s patterned and bare wafer inspectors, e-Beam systems help our customers quickly identify and understand yield-impacting issues—enabling faster, more effective actions to correct the manufacturing process.

What You'll Do

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.

Sr. Reliability Engineer – SEM Systems

Join a team solving complex reliability challenges on advanced SEM systems used in semiconductor manufacturing. This is a hands-on engineering role where you'll identify failure mechanisms, investigate root causes, and drive real-world solutions that improve system performance and uptime. We're looking for someone who enjoys working closely with hardware, digging into the data, and taking ownership from problem identification through implementation, not just analyzing issues, but fixing them.

Job Duties, but not limited to:

• Drive reliability and uptime of SEM systems used for wafer inspection and review, targeting industry-leading system availability.
• Evaluate system designs, manufacturing processes, and acceptance testing to identify potential failure modes before they reach customers.
• Develop and implement Design of Experiments (DOE) to validate component and system performance, reliability, and durability.
• Define and assess accelerated life testing, environmental testing, and stress testing, including thermal, vibration, vacuum, contamination, and high-voltage conditions.
• Establish reliability requirements and qualification plans for critical components, subsystems, and complete systems.
• Review design, manufacturing, and test data to ensure products consistently meet reliability and performance targets.
• Partner with suppliers to qualify components, validate manufacturing processes, and ensure compliance with technical requirements.
• Lead factory acceptance and qualification activities to verify products meet specifications before release.
• Investigate field and factory failures using statistical analysis, data science techniques, and advanced modeling tools.
• Drive corrective actions and continuous improvement efforts based on reliability data and root-cause findings.
• Influence engineering, manufacturing, and supplier teams to implement solutions that improve product robustness and long-term performance.

Qualifications, but not limited to:

• Advanced degree in Physics, Mechanical Engineering, Electrical Engineering, Reliability Engineering, or a related technical field.
• 10+ years of experience developing, supporting, or improving semiconductor capital equipment.
• Deep understanding of Scanning Electron Microscopy (SEM) or other precision systems (eg. optical microscopy, lithography systems, etc..)
• Familiar with some or all the following:
  • Electron optics
  • Precision mechanical systems
  • High-vacuum systems
  • High-voltage systems
  • Cleanroom and contamination control environments
  • Wafer handling and positioning systems
  • Motion control and automation
• Experience developing qualification plans and executing reliability testing for complex electromechanical systems.
• Strong background in failure analysis, root cause investigation, and reliability engineering methodologies.
• Experience working directly with suppliers on component qualification and manufacturing readiness.
• Ability to influence technical decisions across engineering, manufacturing, quality, and supplier organizations.
• Knowledge of semiconductor industry standards, including SEMI standards and ISO quality systems is a plus.
• Willing to travel 15% international

Minimum Qualifications

Doctorate (Academic) Degree and related work experience of 5 years; Master's Level Degree and related work experience of 8 years; Bachelor's Level Degree and related work experience of 12 years
