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 Broadband Plasma (BBP) division is the market-leading optical inspection system used by logic, foundry, and memory customers to detect critical defects at advanced nodes. These tools combine broadband plasma technology with unmatched sensitivity and speed to support high-volume manufacturing.

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.

We are seeking a highly experienced Senior eBeam Systems Design Engineer to lead the design, modeling, optimization, and performance improvement of advanced electron beam systems used in next-generation semiconductor inspection and metrology platforms. This role requires a unique combination of deep theoretical expertise in electron optics, strong systems engineering capability, and hands-on experience working directly with complex eBeam columns and subsystems. The successful candidate will serve as both a designer and practical problem solver, leveraging simulation tools and real-world system observations to improve performance, reliability, and imaging capability.

As a technical leader, you will independently drive high-impact projects, collaborate across multidisciplinary teams, and communicate complex technical concepts to engineers, scientists, and leadership stakeholders.

Key Responsibilities

• Lead the design, analysis, and optimization of electron beam columns and electron-optical subsystems.
• Develop and refine electron optics architectures for advanced semiconductor inspection and metrology systems.
• Perform detailed electron-optics simulations to evaluate system performance and identify improvement opportunities.
• Model and analyze magnetic lens systems, magnetic fields, and charged particle trajectories.
• Utilize simulation tools such as MEBS (Munro Electron Beam Software), OPERA, and Monte Carlo modeling environments to predict and optimize system behavior.
• Perform magnetic field modeling and magnetic lens design to improve beam quality, resolution, throughput, and overall system performance.
• Drive system-level investigations by directly working with hardware to observe, evaluate, and diagnose electron column performance.
• Analyze experimental data and correlate simulation results with real-world system behavior.
• Collaborate with electrical, mechanical, software, controls, and physics teams to develop integrated system solutions.
• Independently lead complex technical projects from concept through implementation and validation.
• Identify performance limitations and develop innovative solutions to improve system capability and manufacturability.
• Communicate technical concepts, simulation results, and design recommendations to cross-functional teams and leadership.
• Participate in design reviews and provide technical mentorship to engineering teams.

Required Qualifications

• MS or PhD in Physics, Applied Physics, Electrical Engineering, or a closely related technical field.
• 6+ years of experience developing, designing, or optimizing electron beam systems, charged particle systems, or electron optical instrumentation.
• Deep expertise in electron optics and electron-optical system design.
• Strong experience with MEBS (Munro Electron Beam Software) or equivalent electron-optics simulation tools.
• Experience with electron beam column architecture and system-level design.
• Expertise in magnetic lens design, magnetic field modeling, and charged particle trajectory analysis.
• Experience performing Monte Carlo simulations and applying simulation results to improve electron beam system performance.
• Strong systems engineering mindset with the ability to connect subsystem behavior to overall system performance.
• Hands-on experience operating, troubleshooting, and evaluating complex electron beam systems.
• Ability to independently lead technical projects with minimal direction.
• Strong verbal and written communication skills with the ability to present technical content to diverse audiences.

Preferred Qualifications

• PhD in Physics, Applied Physics, or Electrical Engineering.
• Experience with semiconductor inspection, metrology, microscopy, or charged particle instrumentation.
• Experience using OPERA for electromagnetic modeling and magnetic field simulation.
• Experience correlating simulation models with experimental system data.
• Knowledge of electron source technologies, beam formation, focusing systems, and detector interactions.
• Experience developing next-generation electron beam architectures and performance enhancement strategies.

What You'll Bring

• A passion for solving challenging electron-optics problems.
• The ability to combine theoretical modeling with hands-on system evaluation.
• Strong ownership and accountability for technical outcomes.
• A collaborative mindset coupled with the ability to operate independently in highly complex technical environments.
• The capability to serve as a subject matter expert and technical leader for advanced eBeam technology development.
