Grid Stor is seeking an experienced Director, Large Load Interconnection to lead the technical strategy and execution of large load interconnections supporting hyperscale data centers and advanced energy infrastructure across North America.

This role will lead Front-of-the-Meter (FTM) and Behind-the-Meter (BTM) interconnection strategy for projects incorporating battery energy storage systems (BESS), hybrid generation, renewable energy, and utility-scale transmission infrastructure. The ideal candidate brings deep expertise in large load interconnections, transmission planning, EMT modeling, and utility coordination across multiple ISO/RTO markets.

The position partners closely with Development, Engineering, EPC, Commercial, and external stakeholders to deliver reliable, cost-effective, and scalable power solutions for next-generation data center developments.

• Lead large load interconnection strategy across ERCOT, CAISO, PJM, MISO, SPP, WECC, and utility service territories.
• Manage the complete lifecycle of Front-of-the-Meter (FTM) and Behind-the-Meter (BTM) interconnection processes, including applications, system studies, utility negotiations, and interconnection agreements.
• Develop technical solutions for co-located BESS, hybrid generation, renewable energy, and hyperscale data center projects.
• Serve as the primary technical interface with utilities, ISOs/RTOs, transmission owners, consultants, and equipment manufacturers.
• Evaluate and optimize data center power architectures, including BESS, hybrid generation, UPS integration, and 2N/N+1 redundancy strategies.
• Lead or review transmission planning, power flow, transient stability, EMT, short circuit, harmonic, and grid compliance studies.
• Support PSCAD, PSS®E, PSLF, EMTP-RV, or equivalent modeling activities for interconnection and system performance.
• Coordinate Hardware-in-the-Loop (HIL) testing and model validation activities with OEMs, EPCs, and utilities.
• Identify interconnection risks, transmission constraints, schedule impacts, and cost exposure while developing mitigation strategies.
• Monitor evolving ISO, utility, and regulatory requirements and incorporate changes into project development strategy.
• Provide technical leadership and mentorship to internal teams and external engineering consultants.

• Bachelor's degree in Electrical Engineering or related discipline.
• 10+ years of experience in transmission planning, large load interconnection, or power systems engineering.
• Demonstrated experience supporting hyperscale data center or other large load interconnections.
• Strong understanding of utility transmission systems, substations, and interconnection processes.
• Experience…
