Group/Division

With over 40 years of semiconductor process control experience, chipmakers around the globe rely on KLA to ensure that their fabs ramp next-generation devices to volume production quickly and cost-effectively. Enabling the movement towards advanced chip design, KLA's Global Products Group (GPG), which is responsible for creating all of KLA’s metrology and inspection products, is looking for the best and the brightest research scientist, software engineers, application development engineers, and senior product technology process engineers. The RAPID division is the world leading provider of reticle inspection solutions for the semiconductor industry. The company provides inspection solutions to both the mask shops and the semiconductor fabs to ensure that lithography yields are consistently high thus enabling cost-effective manufacturing.

Job Description/Preferred Qualifications

As a Senior System Design Engineer with a focus on optical systems, you will lead the design, integration, and optimization of complex electro-optical platforms. You will be responsible for ensuring precise optical alignment, managing tight tolerances, and driving system-level performance in KLA’s next-generation inspection and metrology tools.

Key Responsibilities

• Lead system-level design and integration of high-precision optical instruments.

• Define and manage optical alignment strategies and tolerancing budgets across subsystems.

• Collaborate with optical, mechanical, and software teams to ensure robust alignment methodologies and maintain optical performance throughout the product lifecycle.

• Perform tolerance analysis (e.g., Monte Carlo simulations, sensitivity studies) to guide design decisions and ensure manufacturability.

• Develop alignment procedures and tools for both R&D and manufacturing environments.

• Drive root cause analysis and resolution of optical performance issues.

• Support system validation, calibration, and verification activities.

• Mentor junior engineers and contribute to technical reviews and design best practices.

Qualifications

• Master’s or Ph.D. in Optical Engineering, Physics, Systems Engineering, or a related field.

• 8+ years of experience in system design and integration of complex optical or electro-optical systems.

• Deep understanding of optical alignment techniques, tolerance analysis, and system-level error budgeting.

• Experience with precision opto-mechanical assemblies, interferometry, and metrology tools.

• Strong communication and cross-functional collaboration skills.

Preferred Skills

• Experience in semiconductor capital equipment or other high-precision industries.

• Familiarity with model based system engineering (MBSE) and systems modeling language (SysML)

• Familiarity with active alignment techniques and automation in optical assembly.

• Knowledge of design for manufacturability (DFM) and reliability (DFR) in optical systems.

• Proficiency with optical design and analysis tools (e.g., Zemax, Code V, FRED) and system modeling tools (e.g., MATLAB, Python).

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

Base Pay Range: $180,000.00 - $306,000.00 Annually
