Job description

This role is for a senior mechanical engineer at KLA, focusing on the development of complex mechanical systems for advanced e-beam inspection tools. The position involves significant technical ownership and collaboration across various engineering disciplines to address challenges in semiconductor technology. The team is dedicated to delivering high-impact solutions that enhance manufacturing processes and product quality. This opportunity allows for hands-on engineering while influencing the architecture of future platforms.

Requirements

  • Strong mechanical engineering fundamentals with experience designing complex electromechanical or precision-engineered systems.
  • Experience on vacuum chamber design is required.
  • High voltage related design experience is desired.
  • Demonstrated experience owning hardware or subsystem development from concept through integration and validation.
  • Strong knowledge of precision machine design, including GD&T, tolerance analysis, materials, machine elements, and fabrication methods.
  • Experience with mechanical analysis and simulation, such as structural, thermal, vibration, fluid, or FEA.
  • Proficiency with 3D CAD tools; Creo/ProE experience is beneficial.
  • Experience integrating mechanical hardware into complex multidisciplinary systems.
  • Ability to lead technical decisions, communicate trade-offs, and drive resolution of complex engineering problems.
  • Strong cross-functional leadership and communication skills.

Responsibilities

  • Lead the development of complex mechanical subsystems and contribute to overall platform architecture.
  • Translate customer, product, and system needs into clear engineering requirements and technical solutions.
  • Drive technical decisions with a high degree of independence, including feasibility studies, trade-off analysis, risk retirement, and requirements definition.
  • Own solutions throughout the full development lifecycle, from concept and detailed design through prototype, integration, validation, release, and production.
  • Develop mechanical designs and engineering drawings using 3D CAD tools.
  • Lead or perform engineering analysis including thermal, fluid, vibration, structural, tolerance, and finite element analysis.
  • Drive prototype builds, material procurement, subsystem integration, system-level testing, and performance validation.
  • Lead design reviews and technical discussions across multidisciplinary and cross-division teams.
  • Partner with manufacturing and suppliers to improve manufacturability, scalability, quality, and technical readiness.
  • Develop assembly, integration, test, troubleshooting, and service procedures to support production and field teams.
  • Lead resolution of complex system integration, manufacturing, and field issues.
  • Capture and communicate best-known methods to strengthen organizational capability.
  • Mentor engineers and provide technical guidance across multiple experience levels.
  • Influence technology roadmaps and the architecture of future product platforms.

Benefits

  • Employees at KLA are often offered competitive pay with bonuses, a 401(k) match, an employee stock purchase program, and financial perks like student-debt assistance, planning support, and group insurance discounts. Health and lifestyle benefits typically include medical/dental/vision, life and other voluntary coverages, paid time off and holidays, family leave, backup care, wellness rewards, gym discounts, and community-volunteering opportunities. Employees also get strong growth support through tuition reimbursement, KLA’s corporate learning center, education awards, and engineering certification programs.
