Network Engineer, BMS/EPMS
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!
How We Operate
Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
The Network Team
Examples of key problems the team is working on
Network the control plane that keeps gigawatts safe. BMS, EPMS, and SCADA traffic ride the networks you build, and at this scale a dropped control packet is a facility incident, not a retry.
One controls architecture, stamped across every site. A standardized, segmented controls network deployed at every new build, integrated with landlord and partner OT domains without inheriting their risk.
Make oversubscription safe at machine speed. Our sites run more IT nameplate than utility capacity, managed by a metering-to-load-shed control loop that must respond in seconds across the network you own.
Role Scope
Own the controls network layer for BMS, EPMS, and SCADA across all sites: a standardized architecture of firewalls and border leaf/spine, a dedicated BMS spine in the MDF, IDFs placed within copper reach of field devices, and MACSec-capable L3 switching for every IP endpoint.
Build the telemetry and command paths for our Ignition SCADA platform (redundant per-MDF server stacks, 1-second sampling), including the demand-management loop where electrical metering detects overload, SCADA decides, and load-shed and shutdown paths execute in seconds so sites safely run more IT nameplate than utility capacity.
Engineer failure modes deliberately so equipment islands gracefully on comms loss and every degraded state of the network is known and bounded before it happens.
Integrate with landlord-owned and partner-owned OT domains at colocation sites through firewalled boundaries, replicating historian data across a controlled edge without flattening security domains.
Enforce the OT security posture: Palo Alto-class firewalled OT edges, OT-aware monitoring, and strict segmentation between production, controls, and enterprise networks.
Embed the controls network in site design from day one, working with facility engineers, controls and commissioning engineers, MEP designers, and security so the network is commissioned with the building.
Ability to travel up to 25% of the time to our Data Centers and construction sites
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly,tell us where you would .
You've designed and operated OT/ICS networks (BMS, EPMS, SCADA) in production facilities where a control outage had physical consequences.
Familiarity with industrial din-rail mount switch types. They will pop up here and there (esp on OTS equipment), good to know how to wrangle them.
You work in BACnet/IP, Modbus TCP, and OPC UA daily and know their failure modes on a real network, along with the IT layers underneath: routing, multicast where needed, QoS, and PTP or NTP time distribution.
You've built segmented industrial architectures with firewalled IT/OT boundaries and held the line against pressure to flatten domains for convenience.
You've sat between controls engineers and network engineers and translated both directions, turning a control sequence into VLANs, routes, and firewall rules and explaining a network constraint back in controls terms.
You've commissioned networks alongside building commissioning, proving control paths end to end before the facility carried load.
You document architectures well enough that another engineer can build the next site from your drawings without calling you.
Bonus: IEC 62443 or similar OT security depth. Ignition or a comparable SCADA platform. Data center MEP systems familiarity. Electrical metering and power quality systems.
Bonus: IEC 61850 or similar Power System communication depth. Familiar with networking electrical protection equipment (via GOOSE, GSE, etc) and trade-offs between major power system vendor hardware.
We are committed to pay equity and transparency.
