• Pay Rate: $50-59/hr
• ONSITE

• Lead system-level design, analysis, and troubleshooting of etching, and 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
• 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 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
• 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

• Bachelor’s degree in Mechanical Engineering or related field
• 5–7 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)

• 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)

• This is a unique opportunity to support our client; one of the area’s largest semiconductor manufacturing companies. Medical benefits and 401K are available.
