Network Engineer, BMS/EPMS

We exist to make humanity more free. 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. 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.

About the role

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.

Responsibilities

• Design and operate OT/ICS networks (BMS, EPMS, SCADA) in production facilities where a control outage had physical consequences.
• Work in BACnet/IP, Modbus TCP, and OPC UA daily and understand their failure modes on a real network, along with the IT layers underneath: routing, multicast where needed, QoS, and PTP or NTP time distribution.
• Build segmented industrial architectures with firewalled IT/OT boundaries and maintain strict segmentation between domains.
• Translate between controls engineers and network engineers, turning control sequences into VLANs, routes, and firewall rules and explaining network constraints in controls terms.
• Commission networks alongside building commissioning, proving control paths end to end before the facility carries load.
• Document architectures thoroughly so another engineer can build the next site from your drawings without needing to consult you.

Requirements

• Experience designing and operating OT/ICS networks in environments where control outages have physical consequences.
• Familiarity with industrial din-rail mount switch types.
• Daily hands-on experience with BACnet/IP, Modbus TCP, and OPC UA, including their failure modes and underlying IT layers (routing, multicast, QoS, PTP/NTP).
• Experience building segmented industrial architectures with firewalled IT/OT boundaries.
• Ability to translate technical requirements between controls engineers and network engineers.
• Experience commissioning networks alongside building commissioning.
• Strong documentation skills to enable replication of architectures without direct involvement.

Nice-to-have Skills

• IEC 62443 or similar OT security expertise.
• Experience with Ignition or comparable SCADA platforms.
• Familiarity with data center MEP systems, electrical metering, and power quality systems.
• IEC 61850 or similar Power System communication depth.
• Experience networking electrical protection equipment (via GOOSE, GSE, etc.) and understanding trade-offs between major power system vendor hardware.
