Job Description We are seeking a highly motivated Mechanical/Opto‑Mechanical Engineer to lead initiatives focused on energy reduction and purge gas optimization across advanced semiconductor equipment platforms. This role combines physics‑based modeling, optical/mechanical system design, and experimental validation to reduce energy consumption and minimize use of high‑cost and high‑impact purge gases. Key Responsibilities Modeling & Simulation: develop multi‑physics models (CFD, thermal, optical path interactions) to analyze gas flow behavior and purge efficiency, heat transfer and thermal stability, optical contamination and environmental sensitivity; simulate purge gas distribution and consumption; perform trade‑off analyses between purge reduction, optical performance, and system reliability. Design & Engineering: design and optimize opto‑mechanical assemblies with reduced reliance on purge gases; improve sealing strategies, enclosure designs, and flow paths; collaborate with optics, systems, and process engineers; implement energy‑efficient architectures. Testing & Validation: develop and execute test plans to validate modeling predictions; instrument systems to measure gas flow rates and distribution, temperature gradients, optical performance; correlate experimental data with simulation models. Sustainability & Cost Reduction: drive initiatives to reduce purge gas consumption, overall tool energy usage; quantify cost savings and environmental impact; support compliance with internal sustainability goals and external regulations. Cross‑Functional Collaboration: partner with optical engineering, mechanical design, process engineering, product safety & environmental compliance teams; contribute to system‑level architecture decisions for next‑generation tools. Required Qualifications Degree in Mechanical Engineering, Optical Engineering, Physics or related field. 5+ years of experience in mechanical or opto‑mechanical system design. Strong experience with CFD and thermal modeling tools (e.g., ANSYS Fluent, COMSOL). Experience with mechanical design (CAD) and tolerance analysis. Understanding of gas flow dynamics and contamination control. Understanding of optical system sensitivity to environment (temperature, vibration, contamination). Preferred Qualifications Experience with purge gas systems in semiconductor tools. Knowledge of cleanroom and vacuum environments. Familiarity with sustainability and energy efficiency metrics. Experience integrating modeling with experimental validation. Background in thermal management of precision optical systems. Compensation and Benefits Base Pay Range: $97,000.00 – $164,900.00 annually. Primary Location: USA‑MI‑Ann Arbor. KLA's total rewards package includes medical, dental, vision, life, 401(k) with company match, ESPP, student debt assistance, tuition reimbursement, development and career growth opportunities, financial planning benefits, wellness benefits, paid time off, paid holidays, and family care and bonding leave.
