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 demans for HPC, AI, and ML workloads. Their work directly influences system uptime, scalability, and the successful deployment of high-density compute infrastructure. Key Responsibilities 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 . Electrical System Design & Documentation Create, maintain, and 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 architectures Produce detailed electrical schematics, load calculations, breaker coordination studies, and arc‑flash analyses Maintain documentation libraries, revision control, and design standards for electrical infrastructure Data Center Infrastructure Engineering Design and support electrical systems for new data‑center builds, expansions, and retrofits Evaluate site power availability, utility interconnect requirements, and MV/LV distribution strategies 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 High‑Power HPC/AI/ML System Support Architect…
