Job description

About Fluidstack

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

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.

Benefits

• Competitive total compensation package (cash + equity).
• Retirement or pension plan, in line with local norms.
• Health, dental, and vision insurance.
• Generous PTO policy, in line with local norms.

The base salary range for this position is $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location. This range represents our good faith estimate of the compensation for this role at the time of posting. Total compensation may also include equity in the form of stock options.

We are committed to pay equity and transparency.
