Responsibilities
Lead and support mechanical design efforts across the full project lifecycle—from concept development through commissioning—focused on chilled water systems, air distribution, and equipment layout for data centers
Coordinate closely with Development, Procurement, Construction, and Operations teams, as well as Engineers of Record (EoRs), consultants, and contractors to resolve design issues and maintain alignment across disciplines
Research and develop emerging trends and advanced technologies to improve thermal management, HVAC systems, and mechanical infrastructure for enhanced performance and energy efficiency in data centers
Review and manage mechanical design documentation, including drawing sets, piping schematics, airflow diagrams, shop drawings, submittals, and commissioning reports
Ensure all mechanical systems comply with project requirements, internal standards, ASHRAE guidelines, and local building codes
Track and report on design progress, holding partners accountable to key milestones and deliverables. Proactively identify schedule risks and recommend solutions to stay on track
Support cost estimation and change management for mechanical scope, including evaluating value engineering proposals and reviewing EoR scopes and resources
Participate in factory witness testing, site inspections, TAB, and commissioning activities to confirm system readiness and integration with building management systems
Collaborate with other engineering disciplines to ensure mechanical systems are well-integrated with electrical, structural, and controls designs
Maintain accurate project records, track technical decisions, and provide routine updates to internal stakeholders
Contribute to project risk assessments by identifying mechanical-related risks and mitigation strategies
Assist in onboarding new team members and sharing design standards, workflows, and technical best practices
Support continuous improvement by incorporating lessons learned and contributing to updates of internal design tools, templates, and processes
Partner with the construction team during field execution to provide technical guidance and resolve installation challenges
Work with the operations team to support system handover, provide design intent context, and help ensure maintainability and operability of mechanical systems post-turnover
Qualification
Required
Bachelor's degree in Mechanical Engineering with an emphasis on data center mechanical systems and mission-critical facilities
Revit BIM design experience required, including coordination of large-scale mechanical rooms, central plants, and equipment layouts
Proficiency in data center cooling system design, including air-based and liquid-based cooling strategies, chilled water plants, DX systems, rear-door heat exchangers, and direct-to-chip cooling
