Sr Mechanical Engineer

Job Title: Mechanical Engineer Semiconductor FacilitiesJob DescriptionThis role leads the mechanical engineering design for advanced semiconductor and mission-critical facilities, from initial concept through construction and commissioning. You will design complex HVAC, utility, and process systems that support semiconductor tool installations and high-performance cleanroom environments, while ensuring safety, reliability, and compliance with industry standards and codes. The position combines technical leadership, detailed engineering analysis, cross-functional collaboration, and mentoring of junior engineers within a safety-focused culture.

Responsibilities

• Serve as the lead mechanical engineer on projects, providing clear technical direction and resolving design challenges from concept through construction.
• Lead the design of semiconductor tool installations, including development of utility matrices and point-of-use (POU) connections for process cooling water (PCW), exhaust, specialty gases, chemical drains, and other critical utilities.
• Design and specify complex HVAC systems for advanced semiconductor manufacturing facilities, including air handling units, variable air volume (VAV) systems, chillers, boilers, pumping systems, and exhaust ventilation.
• Engineer ultra-pure water (UPW), reverse osmosis (RO), deionized water (DI), and process heating and cooling systems that meet stringent reliability and contamination-control requirements.
• Develop exhaust, chemical delivery, and waste systems for hazardous production materials (HPMs), ensuring compliance with ASHRAE, SMACNA, SEMI, and applicable regulatory standards.
• Establish and maintain engineering standards and best practices that promote safety, operational reliability, and long-term maintainability of mechanical and utility systems.
• Perform thermodynamic, hydraulic, and psychrometric analyses to improve system efficiency, reliability, and operational performance.
• Develop detailed sequences of operation (SOO) and support integration of controls to ensure seamless interaction between mechanical systems and facility automation platforms.
• Validate designs through engineering calculations, modeling, and code compliance reviews in accordance with local, state, and industry requirements.
• Evaluate system performance and identify opportunities to improve energy efficiency, uptime, and overall facility effectiveness.
• Coordinate closely with electrical, structural, process, chemical, controls, and architectural teams to deliver integrated facility solutions.
• Lead design reviews, constructability assessments, HAZOP studies, and technical coordination meetings throughout the project lifecycle.
• Interpret semiconductor tool vendor requirements and translate them into optimized utility designs that support successful equipment installation and startup.
• Support construction activities by responding to RFIs, reviewing submittals, performing field inspections, providing site support, and participating in commissioning efforts.
• Prepare and review engineering deliverables, including drawings, specifications, calculations, reports, and as-built documentation, ensuring technical accuracy and code compliance.
• Serve as a technical mentor to engineers and designers, promoting engineering excellence and professional growth within the team.
• Review and provide guidance on design work, calculations, and deliverables produced by junior team members.
• Contribute to the development and refinement of engineering standards, design guides, lessons learned, and continuous improvement initiatives.
• Foster a safety-first culture through proactive design decisions that protect personnel, facilities, and surrounding communities.
• Support knowledge sharing and technical training initiatives across the engineering organization.

Essential Skills

• Bachelor's degree in Mechanical Engineering or a closely related engineering discipline.
• Experience supporting semiconductor manufacturing, advanced technology, cleanroom, life sciences, or mission-critical facilities.
• Strong knowledge of HVAC systems, including air handling units, VAV systems, chillers, boilers, pumping systems, and exhaust ventilation.
• Strong knowledge of process cooling water (PCW), ultra-pure water (UPW), reverse osmosis (RO), deionized water (DI), exhaust, chemical distribution, and facility utility systems.
• Working knowledge of ASHRAE, SEMI, SMACNA, and applicable building codes and standards.
• Proven ability to lead multidisciplinary engineering projects from concept through commissioning.
• Demonstrated ability to interpret tool vendor requirements and translate them into optimized utility and mechanical designs.
• Experience performing thermodynamic, hydraulic, and psychrometric analyses for system optimization.
• Ability to develop sequences of operation (SOO) and support controls integration with facility automation platforms.
• Experience preparing and reviewing engineering drawings, specifications, calculations, reports, and as-built documentation.
• Strong collaboration skills for working with electrical, structural, process, chemical, controls, and architectural teams.
• Demonstrated ability to lead or participate in HAZOP studies, constructability assessments, and design-phase risk reviews.

Additional Skills & Qualifications

• Professional Engineer (PE) license preferred or the ability to obtain a PE license.
• Direct experience with semiconductor fabrication tool installation design, including utility matrices, POU connections, HPM exhaust systems, and ultra-pure water infrastructure.
• Experience leading HAZOP studies, constructability reviews, and design-phase risk assessments for complex facilities.
• Familiarity with SEMI standards such as S2, S8, F15, and related semiconductor equipment safety standards.
• Track record of mentoring junior engineers or formally leading small project engineering teams through complex mechanical design challenges.
• Experience contributing to engineering standards, design guides, and lessons learned repositories.
• Interest in continuous improvement, knowledge sharing, and technical training within an engineering organization.
