As a Mechanical Engineer, you'll leverage your strong foundation in physics, mathematics, and materials science to process and resolve mechanical problems, design and implement custom mechanical tooling and associated processes, and enable the handling, assembly, and disassembly of parts, components, sub-assemblies, and final assemblies throughout the product life cycle. You'll be responsible for designing, developing, and modifying mechanical engineering layouts, schematics, and specifications. You will oversee manufacturing and installation processes, ensuring adherence to industry standards and regulations-- and you'll coordinate the procurement and assembly of mechanical components and equipment for design projects, identifying sources of critical parts and subsystems to resolve technical issues. **Role Responsibilities** **System-Level Engineering (Core COE Focus)** - Lead system-level design, analysis, and troubleshooting of chemical/gas delivery systems (gas panels, MFCs, FRCs, valves, and subsystems) across multiple business units - Identify root causes of complex field issues (e.g., flow instability, contamination, pressure transients) and drive system-level corrective actions - Develop and validate system-level models (analytical / CFD / digital twin) to predict flow, thermal, and contamination behavior - Define system architecture requirements and drive alignment across component suppliers and internal teams **Testing, Validation & Qualification** - Define, coordinate, and execute system-level and component-level test plans on COE lab test stands - Analyze test data and generate detailed engineering reports to support qualification, reliability, and supplier 8D closure - Drive correlation between lab testing, simulation models, and field performance **Design & Development** - Design and modify mechanical layouts, gas panel schematics, and subsystem architectures for new and existing platforms - Develop specifications for critical flow control components (MFCs, FRCs, MFVs, valves, regulators) - Support design for reliability (DfR), manufacturability (DfM), and serviceability (DfS) for chemical delivery subsystems **AI / Digital Engineering Enablement** - Drive development and deployment of AI-based tools for troubleshooting, knowledge management, and component selection - Partner with software/data teams to structure engineering knowledge for AI applications (e.g., knowledge agents, workflow automation) - Identify opportunities to leverage AI/digital twin to reduce field escalations and accelerate root-cause analysis **Cross-Functional & BU Engagement** - Act as COE technical interface to Business Units (BU), Systems COE, and suppliers - Lead system-level engineering discussions and drive resolution of cross-functional issues - Build consensus across stakeholders and align on roadmap priorities **Supplier & Specification Ownership** - Define and manage mechanical and functional specifications for key suppliers - Support supplier qualification, reliability activities, and change control (ECR, SPS, SNF) - Evaluate new technologies and drive roadmap alignment for next-gen flow control solutions **Minimum Qualifications** - Bachelor's degree in Mechanical Engineering or related field - 4-7 years of experience in mechanical/system engineering development - Strong fundamentals in fluid dynamics, thermodynamics, heat transfer, and gas flow systems - Experience with system-level problem solving (beyond component-level design) - Hands-on experience with lab testing, data analysis, and engineering report generation - Proficiency in CAD tools and engineering documentation (GD&T, drawings, specifications) **Preferred Qualifications** - Experience in semiconductor equipment, chemical delivery systems, or gas handling systems - Knowledge of flow control devices (MFCs, FRCs, valves, regulators) and pressure/flow interactions - Experience with system modeling tools (CFD, MATLAB, Python, or equivalent) - Familiarity with AI/ML applications in engineering (data analysis, automation, knowledge systems) - Understanding of Applied Materials product lifecycle, supplier ecosystem, and qualification processes - Experience working across cross-functional teams and multiple business units - Exposure to digital twin, system simulation, or model-based engineering approaches **Additional Information** **Time Type:** Full time **Employee Type:** Assignee / Regular **Travel:** Yes, 20% of the Time **Relocation Eligible:** Yes The salary offered to a selected candidate will be based on multiple factors including location, hire grade, job-related knowledge, skills, experience, and with consideration of internal equity of our current team members. In addition to a comprehensive benefits package, candidates may be eligible for other forms of compensation such as participation in a bonus and a stock award program, as applicable. For all sales roles, the posted salary range is the Target Total Cash (TTC) range for the role, which is the sum of base salary and target bonus amount at 100% goal achievement.
