There is never a dull moment with us.

As an Applications Development Engineer in the KLA Instruments organization, you will develop, validate and demonstrate advanced applications for existing and next‑generation metrology systems. You will play a critical role in new product introduction (NPI), working closely with engineering, product management, marketing and global applications teams to ensure our tools deliver maximum value to customers.

This role is based in Milpitas, with hands‑on access to development tools and close collaboration with R&D. Occasional customer and regional support travel is expected.

• Develop and implement new applications for prerelease and released Instruments products, including stylus profilers, optical profilers, thin‑film reflectometers, sheet‑resistance tools and related platforms
• Design and execute characterization, feature and verification test plans for NPI programs (alpha, beta and ramp phases)
• Analyze measurement data, identify performance gaps and provide clear, actionable feedback to hardware, software and systems engineering teams
• Generate application notes, Best Known Methods (BKMs), characterization reports and internal technical documentation

• Lead or support alpha and beta testing for new products and features, including test definition, sample selection, execution and reporting
• Support demo and pilot tools during ramp, ensuring readiness for customer evaluations and early adopters
• Participate in cross‑functional design reviews, trade‑off discussions and roadmap alignment with Product Management and Marketing

• Support customer demos, head‑to‑head comparisons and value demonstrations to drive product adoption
• Investigate customer process and application challenges and translate them into effective metrology solutions
• Develop and deliver technical training for field applications engineers, channel partners, service teams and customers
• Provide onsite or remote customer support as needed

• Act as a technical bridge between Engineering, Marketing, Sales, Field Applications or Channel Partners and Customers
• Transfer application knowledge globally to regional applications teams and channel partners through documentation, training and technical reviews
• Contribute to use‑case development, marketing collateral and value messaging for Instruments products

• BS, MS or PhD in Physics, Materials Science, Electrical Engineering, Mechanical Engineering, Optical Engineering, Chemistry or a related technical field
• Strong hands‑on experimental skills and data analysis experience
• Ability to independently design experiments, analyze results and communicate conclusions clearly
• Strong written and verbal communication skills
• Willingness to travel internationally and domestically (typically 10‑40%, depending on project phase)

• Experience with semiconductor or advanced materials metrology (stylus profiling, optical profiling, film thickness, resistivity, surface analysis, etc.)
• Familiarity with NPI / PLC processes and structured…
