Responsibilities

Develop, review, and coordinate design criteria, basis-of-design documents, calculations, specifications, drawings, equipment selections, and technical reports for facility systems, ensuring alignment between electrical and mechanical designs.
Provide technical oversight of electrical systems, including utility service, medium- and low-voltage distribution, substations, switchgear, transformers, UPS systems, generators, grounding, lighting, controls, and power monitoring.
Provide technical oversight of mechanical systems, including HVAC, chilled-water and refrigerant systems, cooling towers, pumps, piping, ventilation, plumbing, fire protection, fuel systems, and associated controls.
Evaluate system capacity, reliability, redundancy, energy efficiency, maintainability, and operational risk, and coordinate integrated solutions for new and existing facilities.
Serve as a senior technical resource for resilient, high-availability infrastructure and critical equipment.
Manage engineering activities from programming and conceptual design through construction, startup, commissioning, turnover, and closeout.
Coordinate internal disciplines and external stakeholders to resolve technical interfaces and support constructability, maintainability, operability, and phased implementation.
Develop and manage scopes of work, requests for proposals, bid packages, technical clarifications, proposal evaluations, contractor recommendations, and contract exhibits; support procurement and vendor selection.
Lead project planning and controls, including engineering budgets, schedules, resource plans, risk registers, decision logs, change management, document control, progress reporting, and technical communications.
Perform and document design, constructability, value engineering, and code compliance reviews; conduct field observations and review submittals, shop drawings, and requests for information; manage punch-list activities and corrective-action verification.
Provide construction administration and field engineering support, monitor contractor performance and installation quality, and verify compliance with approved documents, project requirements, and safe work practices.
Support commissioning and turnover by reviewing test procedures, participating in functional performance testing, resolving deficiencies, verifying training and documentation, and coordinating record drawings and operations and maintenance information.
Conduct facility assessments, due diligence, condition evaluations, capacity studies, reliability and redundancy reviews, and investigations; prepare recommendations, conceptual solutions, implementation plans, and order-of-magnitude cost estimates.
Provide owner’s representative and operational support, including troubleshooting, incident and root-cause investigations, emergency response coordination, vendor oversight, and planning repairs or upgrades in active facilities while minimizing risk and disruption.
Maintain accurate project and asset records for critical systems, equipment, controls, wiring, cabling, and infrastructure modifications.
Build client relationships, identify follow-on opportunities, support proposals and presentations, and strengthen relationships with consultants, contractors, manufacturers, and service providers.
Mentor engineers and project team members, provide technical guidance and quality reviews, share lessons learned, and contribute to Engineering & Construction standards and best practices.
