Data Center Infrastructure Electrical Engineer (PE Required)

Role Summary

The Data Center Infrastructure Electrical Engineer is responsible for designing, maintaining, and optimizing electrical systems that support high‑density, mission‑critical data‑center environments. This role requires deep expertise in medium‑voltage (MV) and low‑voltage (LV) electrical distribution, including switchgear, UPS systems, transformers, and high‑power architectures for HPC, AI, and ML workloads. The engineer will own the creation and upkeep of detailed one‑line drawings, coordinate with cross‑functional teams, and ensure electrical designs meet performance, reliability, and safety requirements. A Professional Engineer (PE) license is required.

Key Responsibilities

• Update MV and LV one‑line drawings, ensuring accuracy across switchgear, UPS systems, transformers, PDUs, RPPs, and distribution networks.
• Develop electrical designs for high‑power HPC/AI/ML clusters, including busway systems, redundant distribution paths, and high‑current delivery architecture.
• Produce detailed electrical schematics, load calculations, breaker coordination studies, and arc‑flash analyses.
• Maintain documentation libraries, revision control, and design standards for electrical infrastructure.

Engineering Design and Support

• Design and support electrical systems for new data‑center builds, expansions, and retrofit implementations.
• Evaluate site power availability, utility interconnect requirements, and MV/LV distribution strategy.
• Specify and review equipment such as MV switchgear, LV switchboards, UPS systems (double‑conversion, rotary, modular), static transfer switches, and transformers.
• Ensure designs meet reliability targets (N, N+1, 2N), fault tolerance requirements, and operational constraints.
• Support architectural electrical solutions for high‑density compute racks, liquid‑cooled systems, and GPU‑accelerated clusters requiring elevated power delivery.
• Work with mechanical and IT hardware teams to ensure electrical infrastructure aligns with cooling, rack layout, and deployment requirements.
• Support power modeling, redundancy planning, and energy‑efficiency strategies for large‑scale AI/ML deployments.

Cross‑Functional Collaboration

• Partner with mechanical, controls, construction, and product development teams to ensure cohesive infrastructure designs.
• Participate in design reviews, vendor evaluations, and commissioning activities.
• Provide electrical engineering expertise to support product roadmaps, modular infrastructure development, and continuous improvement initiatives.

Compliance, Safety & Quality

• Ensure all electrical designs comply with NEC, IEEE, NFPA, utility requirements, and local codes.
• Conduct or oversee short‑circuit, selective coordination, and arc‑flash studies.
• Support root‑cause analysis and corrective actions for electrical issues in production or field environments.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering or related field.
• Active Professional Engineer (PE) license.
• 5+ years of experience in data‑center electrical engineering, mission‑critical facilities, or industrial power systems.
• Expertise in creating and maintaining MV/LV one‑line drawings and electrical documentation.
• Experience with MV switchgear, LV switchboards, UPS systems, transformers, and high‑power distribution.
• Strong understanding of HPC/AI/ML electrical requirements, high‑density rack power, and redundant distribution architecture.
• Architectures. Proficiency with CAD tools and electrical modeling.

Preferred Qualifications

• Experience with modular, skidded, or containerized electrical systems.
• Familiarity with liquid‑cooling electrical integration (pumps, skids, controls).
• Knowledge of utility coordination, substation design, or MV protection schemes.
• Experience with commissioning, FAT/SAT testing, and field troubleshooting.

Impact of the Role

This engineer ensures that the electrical backbone of next‑generation data centers is safe, reliable, and capable of supporting rapidly increasing power demands from HPC, AI, and ML workloads. Their work directly influences system uptime, scalability, and the successful deployment of high‑density compute infrastructure.

Salary for this role is based off degree, years expedience and overall rating.
