Introduction to the job

The mission of the Senior Electron Optics Design Engineer is to design EO system/submodules for the state of the art e-Beam inspection tool. As an Electron Optics Design Engineer, you will design, develop, test, analyze, and implement sub-functions and modules to meet requirements of specified applications.

This position may require access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require the Company to proceed with candidates who are immediately eligible to access controlled technology.

Role and responsibilities

As an Electron Optics Design Engineer for electron beam system, you will perform a variety of engineering tasks including designing, developing, testing, analyzing, troubleshooting and function implementing electron optics modules as you create and evaluate designs to meet requirements of specified applications.

  • Design electron optics modules and sub-system of e-beam inspection tool according to system spec., from concept design to final release for high volume manufacturing;
  • Make design documents from system level to module level, demonstrating design spec. and design principles, details, interfaces according to ASML design process;
  • Perform necessary simulations &calculations needed for electron optics module design, including thermal, vacuum, high voltage, dynamics, mechanical FEM analysis etc.
  • Lead design reviews, error budget development, risk assessment and mitigation, design and execution of experiments, verification processes, validation processes. Provide effective presentation and written evaluations to communicate concepts, designs, test results, etc.
  • Work with vendors and consultants to develop, analyze and fabricate components and sub-assemblies. Trouble shooting and solve problems during parts/module fabrication process;
  • Deeply involve in integration and testing for electron optic system/subsystem, conducting trouble shooting and verifying the design to ensure high quality implementation of designed modules;
  • Transfer design to manufacturing by providing necessary technical processing documents. Technical support to manufacturing team to finish the technical transition from design to mass production;
  • New technology study and development, providing possibilities of new concept design for electron optic modules for future innovation.

Education and experience

  • BS degree with 8+ yrs of experience; MS degree preferred with 2+ yrs of experience; PhD degree with 0 or more experience
  • Master’s degree or PhD acceptable with less years of experience.Preferred fields of study include physics, optics, material science, and mechanical engineering.
  • Must have good understanding of physics and mechanics.


Working at the cutting edge of tech, you’ll always have new challenges and new problems to solve – and working together is the only way to do that. You won’t work in a silo. Instead, you’ll be part of a creative, dynamic work environment where you’ll collaborate with supportive colleagues. There is always space for creative and unique points of view. You’ll have the flexibility and trust to choose how best to tackle tasks and solve problems.
To thrive in this job, you’ll need the following skills:

  • Strong Hands-on skill and trouble-shooting ability;
  • Must be proficient with 3D modeling & 2D detailed drawings using Solidworks and NX.
  • Experience in designing parts and assemblies for ultra-high vacuum is preferred;
  • Experience in designing parts and assemblies for high voltage environment is preferred;
  • Knowledge with materials and material selection, manufacturing and cleaning processes used for making components for electron beam inspection systems.
  • Ability to perform structural and thermal FEA using NX or Comsol.
  • Team work spirit with team members
  • Good capability to evaluate and workoutside contractors, consultants, and machine shops.
  • Experience in designing, fabrication, and testing of mechanical, electro-mechanical modules, and related system interfaces for capital equipment tools is preferred.
  • 2+ years of applicable relevant experience on a semiconductor equipment mechanical product is desired.
  • Excellent written and verbal communication skills.
  • Experience in product lifecycle management tools, Siemens TCE desired.
