Note: The job is a remote job and is open to candidates in USA. Fluidstack is focused on delivering extensive compute infrastructure for AI. They are seeking a Network Engineer to own the controls network layer for BMS, EPMS, and SCADA across all sites, ensuring safety and efficiency in network operations.
Responsibilities
- 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
Skills
- 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
- 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
- IEC 62443 or similar OT security depth
- Ignition or a comparable SCADA platform
- Data center MEP systems familiarity
- Electrical metering and power quality systems
- 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
Benefits
- Offers Equity
- Hybrid work model (HYBRID / Hybrid)
