Mechanical Design Engineer

To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale—faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.

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 ECI Division at KLA delivers chemical metrology and process control solutions that enable precise monitoring and control of critical wet process steps in semiconductor and advanced packaging manufacturing. By providing real time chemical analysis and management systems, ECI helps customers prevent yield limiting defects, stabilize complex metallization and cleaning processes and support next generation device and packaging technologies.

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.

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 through greater chemical process control is KLA's ECI division. ECI is an industry leader of in-process chemistry control, providing the precision of analysis the industry requires for consistent wafer quality while reducing chip feature size. Advanced wafer design drives the need for precision with reliability; ECI strives to lead the design of analytical equipment which can withstand the rigorous demands of the chemical processes for damascene, wafer-level packaging, clean and wet etch processes, with our Prima, Libra, Quanta and QualiSurf product lines.

Successful Mechanical Design Engineer will work in the Mechanical Department of KLA ECI division based in Totowa, NJ.

Will be responsible for the complete design process of new systems, including requirements specification, feasibility studies, cost and scheduling, conceptual and detailed design using CAD systems (Autodesk Inventor, AutoCAD), detailed drawings, design review presentations, procurement of prototype parts, system integration, prototype testing, and handoff to manufacturing. These tasks will require working with other ECI groups such as EE, OPS, Service, and manufacturing engineers to ensure flawless integration and test at the subsystem and system level. Develops the required supporting documentation, such as assembly and test procedures, and service manuals. resolves product issues thru the product phases. Has strong leadership, communication, and problem-solving skills.

• Lead projects/programs for the new analyzer and dosing system variants, owning mechanical scope from requirements through release and post-release support.
• Independently develop and review 3D CAD models, assemblies, and layouts; ensure designs are manufacturable, serviceable, and scalable across product variants.
• Own and review flow diagrams derived from customer requirements and engineering specifications; ensure traceability to mechanical design decisions, interfaces, and verification plans.
• Lead design and integration of complex assemblies (pumps, valves, tubing, fittings, spectrometers, light sources, optical components, electrodes, motors), defining robust mechanical interfaces, alignment/fixture strategies, and serviceability requirements.
• Architect and manage complex customizations for different chemistries, multiple tank configurations, and special facility requirements; translate constraints into clear design requirements and interface definitions.
• Own BOM integrity for systems and options (configuration rules, variant control, alternates, obsolescence mitigation, and cost-reduction opportunities).
• Generate and/or approve complete documentation packages for release (drawings, installation and service documentation, configuration documentation, work instructions, labeling, and supporting engineering documents), ensuring compliance to internal standards.
• Drive and facilitate design reviews (concept, detailed design, DFMEA/risk reviews where applicable), capturing actions and ensuring closure.
• Coordinate cross-functionally with electrical, software, R&D, manufacturing, supply chain, quality, regulatory/compliance, and service teams to resolve integration issues and ensure readiness for production and field deployment.
• Develop test/verification approaches with stakeholders; support build, integration, and qualification activities; analyze failures and drive corrective/preventive actions.
• Own change management for complex or high-impact updates (CO/ECO/ECN), including impact assessments (cost, inventory, service, documentation, and field retrofit considerations).
• B.S. or M.S. in Mechanical Engineering with 5+ years of experience developing electromechanical products from concept through production and sustaining.
