Sr. Mechanical Utilities and Infrastructure Engineer

Primary Duties & 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 a...
