Responsibilities

Mechanical Infrastructure & Utility System Design
Develop and review designs for mechanical utility systems supporting cleanrooms and manufacturing spaces (e.g., HVAC, chilled water, CDA, vacuum, exhaust).
Prepare and evaluate engineering documents including P&IDs, utility schematics, mechanical layouts, and design packages.
Ensure designs comply with ISO cleanroom classifications, building codes, and internal engineering standards.
Lead and participate in design reviews with internal stakeholders and external engineering firms to validate system performance, constructability, and safety.
Provide technical input early in project planning to define system requirements and align design strategies with operational needs.
Construction Engineering, Field Support & Commissioning
Provide on-site engineering support during construction, including system inspections, issue resolution, and verification of mechanical utility installations.
Conduct site walks, field validations, and constructability assessments to ensure alignment with design intent and project specifications.
Coordinate mechanical-related construction activities, ensuring contractor readiness, quality execution, and adherence to project schedules.
Develop and manage RFPs for mechanical utility scope, evaluate proposals, and ensure clear flow-down of technical requirements to subcontractors.
Track progress toward utility readiness milestones and proactively escalate risks or delays.
Ensure design modifications and field changes are captured, communicated, and updated in project documentation.
Support system start-up, testing, commissioning, and turnover of new or upgraded mechanical infrastructure.
Identify opportunities to improve system reliability, performance, and maintainability. Propose roadmaps and recommendations for long-term enhancements; and implement these.
Cross-Functional Coordination & Requirements Alignment
Partner with Project Management, Construction Management, EHS, Facilities, and Equipment Engineering teams to establish infrastructure requirements and confirm system designs meet operational and safety needs.
Collaborate with Equipment Installation teams to align utility availability with tool move-in, hookup, and qualification timelines.
Represent mechanical utility engineering in cross-functional decision-making, schedule reviews, and site readiness discussions.
Communicate technical considerations, risks, and design impacts clearly to both technical and non-technical stakeholders
Engineering Documentation, Standards & Compliance
Generate and maintain accurate mechanical engineering documentation including redlines, as-builts, system matrices, and specifications.
Support development of preventive maintenance procedures and system handoff documentation for newly implemented utilities.
Ensure all mechanical designs and construction activities comply with applicable codes, safety requirements, and internal engineering standards.
Contribute to standardization of mechanical utility design practices, documentation templates, and best practices across projects.
