Originally posted 26 September 2026 by the employer.
About the role
As a Mechanical Engineer at Lam Research, you will design and define mechanical and electro-mechanical systems, contributing to continuous improvement for existing wet processing solutions.
What you'll do
- Support the full life cycle of mechanical and electro-mechanical systems from concept to productization, including conceptualization, designing, CAD modeling, development, and test/validation.
- Design components using a 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 in design reviews.
- Collaborate with suppliers and internal teams to ensure solutions can be manufactured to meet quality, cost, and technical 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.
What you'll need
- Bachelor’s degree in Mechanical Engineering or related field with 8+ years of experience; or Master’s degree with 6+ years’ experience.
- Excellent communication, both written and verbal, and technical presentation skills.
- Highly proficient in 3D CAD tools such as CREO, Siemens NX, ProE, SolidWorks, and others.
- Hands-on experimental and design background coupled with solid engineering skills.
- Highly proficient in fluidic and thermal analysis across highly complex equipment.
Nice to have
- Experience in the Semiconductor industry.
- Experience leading projects or solving problems while managing time and multiple priorities.
Skills: mechanical and electro-mechanical systems, CAD modeling, FEA, thermal analysis, fluid and gas flow dynamics, wet processing solutions
