Mechanical Design Engineer

Company Overview

KLA is a global leader in diversified electronics for the semiconductor manufacturing ecosystem. Virtually every electronic device in the world is produced using our technologies. No laptop, smartphone, wearable device, voice-controlled gadget, flexible screen, VR device or smart car would have been possible without us. KLA invents systems and solutions for the manufacturing of wafers and reticles, integrated circuits, packaging, printed circuit boards and flat panel displays.

The innovative ideas and devices that are advancing humanity all begin with inspiration, research and development. KLA focuses more than average on innovation and we invest 15% of sales back into R&D. Our expert teams of physicists, engineers, data scientists and problem-solvers work together with the world’s leading technology providers to accelerate the delivery of tomorrow’s electronic devices. Life here is exciting and our teams thrive on tackling really hard problems.

There is never a dull moment with us.

• Design the mechanical components of new systems, including conceptual and detailed design using CAD systems (Autodesk Inventor, AutoCAD).
• Create and update 3D CAD models, subassemblies, and system layouts for analyzers and dosers derived from existing platforms.
• Develop flow diagrams and system schematics based on customer requirements and engineering specifications.
• Design and integrate mechanical, fluidic, and optical assemblies (e.g., pumps, valves, tubing, fittings, spectrometers, light sources, optics, electrodes, and motors) to ensure proper mounting, alignment, routing, and service access.
• Create and maintain bills of material (BOMs) to support manufacturing, service, and supply chain.
• Prepare documentation packages for release (drawings, assembly instructions, installation layouts, labeling, and supporting engineering documents) in accordance with internal standards.
• Adapt designs for different chemistries, including material compatibility, wetted-path requirements, sealing approaches, tubing/fitting selection, and corrosion/chemical resistance considerations.
• Adapt designs for varying tank counts and configurations, including sizing/arrangement, mounting, plumbing routing, access/service clearances, and shipping constraints.
• Define facility requirements (utilities, footprint, clearances, and interface constraints) for system layouts based on customer site requirements.
• Create and process Engineering Change Orders (ECOs) / Change Orders (COs) to release new or revised parts, assemblies, and documentation; maintain traceability and accurate revision history.
• Support prototype builds and troubleshooting by performing fit checks, assessing tolerance stack-ups, and conducting root-cause investigations; implement corrective actions.

• Bachelor’s degree in Mechanical Engineering or a related discipline (or equivalent practical experience).
• 2–5 years of mechanical design experience in electro-mechanical products, instruments, or industrial equipment; sustaining engineering experience preferred.
• Proficiency with 3D CAD and drawing creation (e.g., Solid Works, Creo, Inventor, or similar), including assemblies, subassemblies, and configuration management.
• Ability to create/read system schematics and flow diagrams (P&-style) and translate customer requirements into mechanical layouts.
• Working knowledge of fluidic component selection and integration (pumps, valves, tubing, fittings) including routing, serviceability, and leak prevention.
• Exposure to optical/electrochemical/mechatronic hardware integration (mounting, alignment, cable/tube management, access for calibration and maintenance).
• Experience creating and maintaining Bills of Material (BOMs) and supporting documentation packages (drawings, assembly instructions, installation layouts, labeling) to internal standards.
• Understanding of material compatibility and chemical resistance considerations for wetted-path designs (seals, elastomers, plastics, metals) and corrosion/compatibility tradeoffs.
• Knowledge of basic manufacturing methods and DFM/DFA principles; ability to assess tolerance stack-ups and perform fit checks.
• Familiarity with…
