About The Position

As a Mechanical Engineer 4 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.

Requirements

Excellent communication, both written and verbal, and technical presentation skills.
Highly proficient in 3D CAD tools such as CREO & Siemens NX
Hands-on experimental and design background coupled with solid engineering skills.
Solid foundation in mechanical design principles, materials, and manufacturing processes.
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 with semiconductor manufacturing equipment or other complex electro‑mechanical systems.
Familiarity with wet processing, fluid handling, thermal management, or chemical‑compatible mechanical 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

Support the full life cycle of mechanical and electro-mechanical systems from concept to productization including conceptualization, designing, CAD modeling, development, and test/validation.
Designs components using variety of metals, ceramics, quartz, plastics, and advanced coatings.
Ensure documentation aligns with SEMI, Lam standards, and industry best practices for geometric dimensioning and tolerancing (GD&T).
Conduct detailed analysis including structural, finite element analysis (FEA), thermal, heat transfer, stress, vibrations, fluid and gas flow dynamics, and manufacturability to properly specify designs.
Develop and conduct feasibility studies and test plans to characterize and validate design performance.
Prepare high-quality reports and technical presentations to clearly communicate design intent, evaluation, and validation to a diverse audience in design reviews.
Collaborate with suppliers and internal teams to ensure solutions can be manufactured with high-quality, cost-optimized, and to requirements.
Provide key deliverables including Failure Modes and Effects Analysis (FMEA), technical specifications, risk analysis, test specifications, and design review presentations.
Provide technical guidance and mentoring to more junior engineers
