About The Position

As a Mechanical Engineer IV in the WETS Product Group, you will contribute directly to the design, development, and delivery of next-generation wet processing equipment for advanced semiconductor manufacturing. Your work will support critical NPI programs, shaping mechanical designs that meet performance, reliability, cost, and manufacturability goals. In this role, you will translate system-level and subsystem requirements into robust mechanical solutions, working closely with Systems, Process, Electrical, Controls, and Manufacturing Engineering partners. Your contributions will help reduce development risk, accelerate schedules, and enable high-quality products to reach customers on time. This is an execution-focused role with meaningful ownership, where strong fundamentals and good engineering judgment make a visible impact on product success. Additionally, as a Mechanical Engineer IV you will be tasked with mentoring junior engineers in the performance of their duties, passing on your knowledge and experience to the next generation of Engineers at Lam.

Requirements

Bachelor’s degree in Mechanical Engineering or a related discipline.
Minimum of 8+ years of relevant engineering experience, or 6+ years with a Master’s degree, or equivalent practical experience.
Solid foundation in mechanical design principles, materials, and manufacturing processes.
Experience creating detailed mechanical designs using 3D CAD tools (e.g., Creo, NX).
Ability to read and interpret system requirements, drawings, and interface documentation.
Strong problem-solving skills and attention to detail.
Effective written and verbal communication skills.
Ability to work productively in a collaborative, fast-paced, NPI environment

Nice To Haves

Experience in leading projects, or problem solving while managing time and multiple priorities.
Experience with semiconductor manufacturing equipment or other complex electro-mechanical systems.
Strong understanding of wet processing, fluid handling, thermal management, and chemical-compatible mechanical design. The ideal candidate will be extremely knowledgeable on all aspects of fluid handling and fluidic system design.
Exposure to NPI development processes, phase-gate reviews, or prototype builds.
Experience supporting manufacturing ramp or working with global suppliers.
Knowledge of DFx principles (reliability, manufacturability, serviceability, safety).
Interest in technical growth toward senior engineering roles.

Responsibilities

Design and develop mechanical components, assemblies, and subsystems for complex semiconductor manufacturing equipment.
Translate system- and subsystem-level requirements into detailed mechanical designs, layouts, and drawings.
Create and maintain 3D CAD models, detailed drawings, and engineering documentation in accordance with Lam standards.
Perform engineering analysis (e.g., tolerance analysis, thermal-mechanical considerations, structural integrity) to support design decisions.
Collaborate with cross-functional teams including Systems, Process, Electrical, Controls, Software, and Manufacturing Engineering to ensure successful subsystem integration.
Support prototype build, system integration, debug, and validation activities related to New Product Integration (NPI) projects.
Support NPI phase-gate activities (Pre-DR, DDR, CDR, FDR) by delivering assigned mechanical design milestones on schedule.
Participate in design reviews, risk assessments, and failure analysis, contributing to DFMEA and corrective action efforts.
Work with Manufacturing Engineering and Supply Chain partners to ensure designs are manufacturable, serviceable, and cost-effective.
Contribute to sustaining engineering efforts and field issue resolution as needed.
Mentor junior engineers in the performance of their assigned tasks.
