About the Job

Requirements

  • A bachelor's degree or equivalent experience and at least five years of experience in data center mechanical and electrical design and operations, deployment, or installation.
  • Experience with HVAC, chilled water systems, condenser water systems, pump controls, glycols, air-handling units (DX, split, RTU, CRAC, etc.), CRAH, raised-floor systems, hot/cold aisle containment, and building management systems.
  • Understanding of basic electrical theory, including voltage, current, and power; basic circuit design and analysis; and single- and three-phase power systems.
  • Familiarity with data center mechanical and electrical infrastructure design concepts, electrical/UPS topologies, and cooling methodologies including central plant, room cooling, and high-density thermal strategies.
  • Familiarity with industry standards for resilient data center design and Uptime Institute Tier classifications.
  • Experience working across multiple time zones and cross-functional teams.
  • Experience delivering time-sensitive projects under pressure.
  • Understanding of network hardware architecture, data center switching and routing infrastructure, and optical line/transceiver power and thermal profiles.
  • Experience acting as an owner's technical representative, governing external delivery partners, reviewing third-party designs, resolving technical disputes, and driving noncompliance and project risks through documented closure.
  • Expertise in medium- and low-voltage distribution, transformers, generators, UPS systems, switchgear, transfer systems, busway, grounding, protection, and rack-level power architectures for high-density deployments.
  • Understanding of direct-to-chip liquid cooling and the electrical dependencies of coolant distribution units, pumps, controls, facility water systems, and heat-rejection equipment.
  • Experience with construction administration, equipment testing, energization planning, staged commissioning, integrated systems testing, deficiency management, and failure-mode testing.
  • Experience with utility coordination, design-deviation governance, power-quality or incident investigations, and lifecycle management of mission-critical electrical infrastructure.

Responsibilities

  • Translate data center capacity requirements into actionable white-space designs and/or rack plans within individual data center contract constraints for power and cooling.
  • Manage implementation of cage projects with data center providers.
  • Design low-voltage structured cabling, fiber, cross-connect, and conveyance infrastructure, including supporting infrastructure on data center ceilings and floors.
  • Work with the supply chain team on rack integration plans and location deployment qualification.
  • Work cross-functionally with data center engineering and internal capacity planning, network strategy, and security teams to verify scope and solutions and create repeatable standard installation procedures.
  • Own and lead projects to design and implement data center expansions or new data centers on tight deadlines with minimal oversight.
  • Provide technical support during negotiations with external data center partners.
  • Assist with request-for-proposal preparation, review, and cost/engineering analysis.
  • Review one-line diagrams and cooling equations for new and existing data centers.
  • Review and approve power distribution units for the hardware sourcing team.
  • Implement, document, and maintain power-consumption tracking tools and fulfill ad hoc reporting requests.
  • Research power-efficiency technologies and programs.
  • Travel up to 25% to perform infrastructure audits, validate data center construction work and buildouts, and participate in commercial processes.
  • Develop and execute modular and prefabricated data center construction strategies to accelerate deployment and optimize cost efficiency.
  • Perform electrical short-circuit, coordination, arc-flash, and load-flow engineering studies to ensure system reliability and compliance.
  • Partner with hardware sourcing and site reliability engineering/infrastructure teams to validate power distribution unit specifications, rack integration plans, and power distribution topologies across global points of presence.
  • Lead electrical design and end-to-end execution for new sites, expansions, and infrastructure upgrades from site qualification and basis of design through energization, commissioning, and operational handover.
  • Serve as the electrical owner's representative, defining design criteria, scopes, deliverables, responsibility matrices, review gates, and acceptance requirements for data center operators, consulting engineers, contractors, commissioning agents, utilities, and vendors.
  • Design and review utility-to-rack infrastructure, including utility service, transformers, switchgear, generators, UPS systems, transfer systems, modular and prefabricated electrical assemblies, busway, feeders, whips, rack power distribution units, grounding, and metering.
  • Define electrical interfaces and auxiliary-load requirements for direct-to-chip liquid cooling, coolant distribution units, pumps, controls, leak detection, facility water systems, and heat-rejection equipment.
  • Develop and review basis-of-design documents, single-line diagrams, specifications, equipment schedules, calculations, sequences of operation, and interface control documents.
  • Oversee technical acceptance of factory and site acceptance testing, staged Level 1–5 commissioning, integrated systems testing, failure-mode testing, deficiency closure, and turnover documentation.
  • Define electrical power monitoring system, metering, telemetry, and capacity-tracking requirements for operational power and capacity management.

Desired Qualifications

  • A degree in electrical engineering, mechanical engineering, or information technology.
  • Experience in large-scale mission-critical facility infrastructure design, construction, commissioning, and/or operations.
  • Experience with industry standards and building codes, including NFPA 70/National Electrical Code, IEEE, NEMA, ANSI, UMC, ASHRAE, UBC, LEED, and Uptime Institute standards.
  • Knowledge of programming languages.
  • JIRA and Confluence administration experience.
  • AutoCAD experience.
  • Experience with FLOTHERM or Tileflow.
  • Hands-on experience with hardware validation, power/cooling capacity modeling, or thermal simulation tools such as FLOTHERM or Tileflow.
  • Familiarity with systems programming, scripting in Python, Go, or Bash, or automation workflows for power/infrastructure tracking.
  • Experience with NVIDIA DGX, GB200/GB300 NVL, OCP Open Rack, or comparable liquid-cooled GPU platforms and AI factory reference architectures.
  • Experience with ETAP, SKM PowerTools, EasyPower, or equivalent software for dynamic modeling, generator transient analysis, harmonic analysis, and UPS compatibility assessment.
  • Experience with electrical power monitoring system/building management system integration, branch-circuit monitoring, rack-level telemetry, metering, capacity forecasting, or automated infrastructure reporting.
  • Professional Engineer certification or equivalent.
