We are looking to have a Maintenance & Construction Data Center Engineer to join our team at our Aurora, IL data center location. This is an onsite role that will be Monday to Friday 8:00 a.m. to 5:00 p.m. and may require variable shift coverage if needed to assist the team.

The Maintenance & Construction Data Center Engineer leads the construction, expansion, and commissioning of mission-critical infrastructure while maintaining uninterrupted operation of live facilities. This hands-on role manages GCs, MEP subcontractors, and equipment vendors across complex buildouts, ensuring every project is delivered on time, on budget, and without compromising production uptime.

Functions/Responsibilities:

Construction & Project Execution

• Serve as owner's representative on active construction phases — coordinating GCs, MEP subs, low-voltage contractors, vendors, and commissioning agents across expansion projects.
• Develop and enforce construction sequencing plans that protect live infrastructure during phased expansion within operating data centers.
• Review and approve construction documents, shop drawings, submittals, RFIs, and change orders; manage punch lists and project closeout.
• Coordinate power, cooling, and life safety tie-ins to live systems, ensuring all work on energized infrastructure follows approved MOPs and switching sequences.
• Track construction budgets, flag variances, and support capital project forecasting across multi-site expansion programs.

Commissioning & Turnover

• Lead commissioning of newly installed MEP systems (UPS, generators, switchgear, PDUs, chillers, CRAHs, BMS/EPMS) and oversee integrated system testing (IST).
• Manage owner acceptance testing and coordinate turnover to operations with complete documentation packages and as-built drawings.

Critical Systems Operations

• Operate, monitor, and maintain all mechanical and electrical infrastructure in active data center environments; lead critical switching and LOTO activities.
• Respond to alarms and incidents; conduct root-cause analysis with awareness of concurrent construction activities affecting system behavior.
• Support BMS/EPMS monitoring and optimization for PUE, incorporating new infrastructure metrics as expansions come online.

Technical Leadership & Contractor Management

• Primary technical escalation for MEP and construction issues; review and approve contractor MOPs, switching sequences, and safety plans before execution.
• Lead pre-construction and progress meetings; hold GCs and subs accountable to scope, schedule, and site safety standards.
• Mentor operations technicians on construction-related hazards and integration of new infrastructure into daily operations.

Reliability, Documentation & Safety

• Maintain as-built drawings, SOPs, shift logs, and equipment records; ensure documentation is complete at project closeout and transferred to operations.
• Enforce OSHA, NFPA 70E, LOTO, PPE, and permit-to-work requirements for all energized and construction-phase work; conduct contractor safety orientations and jobsite inspections.
• Support audits, compliance documentation, and third-party inspections for both operational standards and construction permitting (NEC, NFPA 75/76, ASHRAE, AHJ).
