A. Technical Leadership & System Design

• Serve as the mechanical authority on projects, by setting design direction, resolving technical conflicts, and ensuring system-level integrity from concept through construction.
• Own end-to-end mechanical design of semiconductor tool installations, from utility matrices and point-of-use (POU) connections (PCW, exhaust, specialty gases, chemical drains) to specialized systems for contamination-controlled environments.
• Lead the design, analysis, and specifications of complex HVAC systems, including air handling units, VAV systems, chillers, boilers, pump hydraulics, and exhaust ventilation, for advanced semiconductor fabrication facilities.
• Engineer ultra-pure water (UPW/RO/DI) infrastructure and process cooling/heating systems that meet the stringent purity and reliability requirements of fab operations.
• Design specialized exhaust and chemical delivery/drain systems for hazardous production materials (HPMs), championing a safety-first approach that meets or exceeds ASME, ASHRAE, NFPA, SMACNA, and SEMI standards.

B. Analysis & Optimization

• Perform detailed thermodynamic, hydraulic, and psychrometric analyses to optimize system performance, energy efficiency, and operational stability, directly influencing fab uptime and yield.
• Develop sequences of operation (SOO) and contribute to control system narratives that ensure seamless integration of mechanical systems with facility controls architecture.
• Apply computational and code-based methods to validate mechanical designs against applicable state/local codes, ASHRAE standards, NFPA 90A, and SEMI guidelines.

C. Cross-Disciplinary Collaboration & Project Delivery

• Drive coordination across electrical, structural, process, chemical, controls, and architectural teams to deliver fully integrated mechanical systems on complex, multi-discipline projects.
• Lead and participate in design reviews, HAZOP studies, and constructability reviews, serving as the…
