About the Role

●        We are looking for a Director of Substation & Grid Engineering to lead substation and grid engineering design for NScale's data center portfolio.

●        This leader will own technical standards for substations, transformers, switchgear, and protection schemes supporting high-density AI/GPU workloads.

●        You will own load and generator interconnection applications and studies, serving as the technical lead on interconnection requests to utilities, ISOs/RTOs, and transmission owners.

●        You will provide technical support to the Utility Development and Power Procurement organizations on interconnection, grid, and substation topics.

●        You will lead a team of Staff Engineers delivering substation and grid engineering design.

What You'll be Doing (Responsibilities)

• Engineering Design & Standards
• ●        Define technical requirements and design standards for substations, transformers, switchgear, protection, and metering.
• ●        Collaborate with internal and external design teams on one-line diagrams, protection schemes, and redundancy strategies (N, N+1, 2N).
• ●        Oversee fault and reliability studies supporting substation and grid design.
• ●        Define electrical topology and one-line requirements for on-site generation integration, including paralleling, synchronization, islanding, and black-start concepts.
• ●        Establish protection and controls philosophy for generation integration (relaying, coordination, fault duty, grounding, synchronization, load sharing).
• ●        Guide equipment specification for generator sets, switchgear, transformers, e-houses, and balance-of-plant, accounting for long-lead risk.
• Load & Generator Interconnection
• ●        Own the preparation, submission, and technical management of load and generator interconnection applications to utilities, ISOs/RTOs, and transmission owners across the portfolio.
• ●        Lead interconnection studies (feasibility, system impact, facilities studies) for both load interconnection and on-site/behind-the-meter generation, tracking queue positions and study timelines.
• ●        Serve as the primary technical point of contact with utility and ISO/RTO interconnection engineering teams, resolving technical issues raised during study review.
• ●        Coordinate interconnection agreement technical exhibits (one-lines, protection requirements, metering, telemetry) in partnership with Legal and Energy Procurement.
• ●        Track interconnection queue risk and grid upgrade requirements, escalating schedule or cost impacts to the VP of Power Infrastructure Design and affected project teams.
• Team Leadership
• ●        Lead and develop a team of Staff Engineers supporting substation and grid engineering.
• ●        Review technical designs and ensure quality and consistency across projects.
• ●        Support career development and technical growth of engineering staff.
• Project Support
• ●        Serve as the substation and grid engineering owner for data center projects from design through energization.
• ●        Visit sites as needed to support commissioning, troubleshooting, and design clarifications.
• ●        Identify and mitigate technical risks related to substation and grid design.
• Cross-Functional Collaboration
• ●        Partner with Utility Development and AI Load Power Strategy teams to align substation design with utility and load requirements.
• ●        Provide technical support to the Utility Development organization on interconnection processes, grid capacity assessments, and site diligence for new and existing markets.

About You (Skills / Qualifications)

Required

●        Bachelor's degree in Electrical Engineering or a related field.

●        8-12+ years of experience in substation design, protection and controls, or grid engineering.

●        Strong ability to interpret and produce electrical one-lines, protection schemes, and system studies.

●        Demonstrated success leading or mentoring engineering teams.

●        Direct experience preparing and managing load and/or generator interconnection applications with utilities, ISOs/RTOs, or transmission owners.

●        Ability to serve as a technical resource to commercial and development teams (e.g., Utility Development, Power Procurement) on interconnection and grid topics.

Preferred

●        Master's degree in Electrical Engineering or Power Systems.

●        Professional Engineer (PE) license.

●        Experience with high-density AI/GPU or HPC data center substation design.

●        Experience with generator OEMs, EPCs, and commissioning providers for large-scale standby/prime power plants.

●        Experience navigating interconnection queues and study processes in multiple ISO/RTO markets.
