Power Delivery Lead (MV Distribution)

Fluidstack•Austin, TX

2d•$250,000 - $330,000

About The Position

Fluidstack is building civilization-scale infrastructure for AI, focusing on delivering 10 to 100s of GWs of compute faster than anyone else. This involves acquiring power, designing and building data centers, and operating them. The Power Generation Team is responsible for building an islanded grid at gigawatt scale, getting power online in months, creating repeatable power blocks, and designing a grid where the largest load answers back. This role is crucial in designing the medium-voltage network that carries power from generation blocks to data halls, ensuring a standard design that scales across sites.

Requirements

Personally built ETAP or SKM PowerTools models of an MV network and produced the load flow, short circuit and cable sizing results that went into issued-for-construction drawings.
Built PSCAD models of switching, energization or islanded events, such as transformer inrush, ferroresonance or inverter-dominated fault response, and changed a design because of what they showed.
Set the protection philosophy and relay settings for a system with limited or variable fault current, and can walk through the coordination that proved it.
Designed MV distribution down to the hardware, including metal-clad switchgear, transformers, cable and duct bank ampacity, and grounding, and defended those choices against NEC, NFPA 70E and IEEE requirements with engineers of record and AHJs.
Designed an MV substation or bus tie scheme that let new capacity energize next to live load, and written the switching sequence the operators followed.
Turned a one-off design into a standard that other engineers applied across multiple projects, and written its design basis clearly enough that they could use it without calling you.

Nice To Haves

Transmission-side study and protection work (IBR interconnection studies, EMT studies, transmission relaying).
Grid-forming and islanded systems (grid-forming inverters, microgrids, remote and mining power).
Licensure to stamp electrical work (PE).
Utility-scale PV and BESS collection systems (34.5 kV collector design).
Data center electrical distribution (MV through UPS).

Responsibilities

Design the medium-voltage network that carries power from each generation block to the data halls, inside the system design basis, as one standard that every site deploys and that grows by adding blocks rather than by redesign.
Design the cluster tie and MV substations that bundle blocks together, covering bus arrangement, transformer selection, tie and transfer schemes, and the switching sequences that let a new block energize next to live ones without an outage.
Size feeders, cable and transformers to the load and run the network studies behind them yourself, including load flow, voltage drop, short circuit, protection coordination, and EMT studies of switching, energization and islanded transients, as models that rerun for each site's layout and block count.
Set the protection philosophy and relay settings for an inverter-dominated network with limited fault current, and write the standard specifications for MV switchgear, transformers, cable and relaying that ship with every block.
Define the envelope the standard holds for, covering block count, feeder length, fault level and load step, set the triggers that send a site to a site-specific study, and fold what each energized site teaches back into the next revision.
