OT/ICS Network Engineer — SCADA & Control-Plane Expert

FluidStack; United States; On-site; USD 120,000 - 180,000; Full time

Job summary

Fluidstack is seeking a Network Engineer for our Network Team to design and operate OT/ICS networks across data centers and sites. You will own the controls network layer, build telemetry paths for SCADA, and work with cross-disciplinary engineers.

Role requires travel up to 25%, deep familiarity with BACnet/IP, Modbus TCP, OPC UA, and firewalled IT/OT boundaries. We value engineers who turn complex control sequences into secure, scalable networks.

Qualifications

• Designed and operated OT/ICS networks in production facilities.
• Familiarity with BACnet/IP, Modbus TCP, and OPC UA daily.
• Built segmented IT/OT networks with strict boundary controls.
• Document architectures so other engineers can build the next site.
• Able to travel up to 25% to data centers or construction sites.
• Bonus: OT security depth (IEC 62443) or Ignition/SCADA experience.

Responsibilities

• Owns the controls network layer for BMS, EPMS, and SCADA across all sites with a standardized architecture of firewalls and network boundaries.
• Build telemetry and command paths for the Ignition SCADA platform, with reliable 1-second sampling and load-shed control loops.
• Engineer failure modes so equipment islands gracefully on communication loss and degraded states are bounded.
• Integrate with landlord-owned and partner-owned OT domains at colocation sites while preserving security domains.
• Enforce the OT security posture across production networks and edge deployments.
• Embed the controls network in site design from day one with facility engineers and security.
