Electrical Engineer, Substation Design

About the Role

We are seeking a senior Substation Design Engineer to support HV/MV substation design across our data center campuses. This is an owner-side role: you will lead substation design from siting and interconnection studies through IFC, construction, FAT, and energization - directing EPCs, consultants, utilities, and equipment manufacturers across a multi-GW portfolio spanning ERCOT, PJM, MISO, and other regions.

You will own the technical quality of design packages, lead the engineering studies that underpin them, and build the substation standards - Basis of Design, standard drawings, equipment specifications that allow Fluidstack to deliver repeatable substations at speed.

Responsibilities

• Lead HV/MV substation design (up to 345 kV and above) and MV distribution interfaces for hyperscale campuses, from concept through IFC and energization.
• Review and approve EPC- and consultant-produced deliverables: physical/structural layouts, electrical drawings, protection & control packages, and construction documents.
• Perform and review engineering calculations and studies: load flow, short circuit, arc flash, grounding and bonding, lightning, insulation coordination, relay coordination, and cable ampacity.
• Develop scopes of work, RFPs, and equipment specifications for long-lead equipment (transformers, switchgear, breakers); run technical bid evaluations and witness factory acceptance tests.
• Provide technical input to utility interconnection processes and agreements (ESAs/CDAs), coordinating with ISOs/RTOs and utility engineering teams.
• Support construction, commissioning, and phased energization planning, including resolution of field issues and RCAs.

Basic Qualifications

• Bachelor's degree in Electrical Engineering.
• 8+ years of experience in HV/MV substation design (transmission and distribution voltages, up to 345 kV).
• Demonstrated ownership of full substation design packages: one-lines/three-lines, physical layouts, grounding, raceway, and protection & control drawings.
• Experience developing equipment specifications, running technical bid evaluations, and witnessing factory acceptance tests for major HV/MV equipment.

Preferred Qualifications

• Professional Engineer (PE) license.
• Owner-side experience at a hyperscale data center operator or large industrial developer.
• Direct experience with utility interconnection processes and technical inputs to ESAs/CDAs in ERCOT, PJM, MISO, or CAISO.
• Experience with both AIS and GIS substation architectures.
• Track record of standards authorship: Basis of Design documents, standard drawing libraries, commissioning scripts, responsibility matrices.
