UST is searching for a System-Level Engineering with strong fundamentals in fluid dynamics, thermodynamics, heat transfer, and gas flow systems.

• Lead system-level design, analysis, and troubleshooting of etching and chemical/gas delivery systems across multiple business units
• Identify root causes of complex field issues such as flow instability, contamination, and pressure transients
• Drive system-level corrective actions and continuous improvement initiatives
• Develop and validate system-level models including analytical, CFD, and digital twin approaches 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 resolution
• 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 including MFCs, FRCs, MFVs, valves, and regulators
• Support design for reliability, manufacturability, and serviceability across chemical delivery subsystems
• Drive development and deployment of AI-based tools for troubleshooting, knowledge management, and component selection
• Partner with software and data teams to structure engineering knowledge for AI applications including knowledge agents and workflow automation
• Identify opportunities to leverage AI and digital twin technology to reduce field escalations and accelerate root-cause analysis
• Act as COE technical interface to Business Units, 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
• Define and manage mechanical and functional specifications for key suppliers
• Support supplier qualification, reliability activities, and change control processes including ECR, SPS, and SNF
• Evaluate new technologies and drive roadmap alignment for next‑generation flow control solutions
• Coach colleagues with less experience and may lead small projects with manageable risks and resource requirements
