Data Center Controls Network Engineer

About this role

OpenAI seeks an experienced OT Network Engineer to design and scale controls and network architectures for high-density AI data centers. You'll define OT network strategies, develop reference architectures, and partner across teams to ensure resilient, secure infrastructure supporting advanced compute environments.

What you'll do

• Design OT network architectures including topology, IP addressing, VLANs, routing, redundancy, and segmentation for AI data centers
• Develop reference architectures, engineering standards, and design templates for controls and automation systems
• Define integration patterns across multiple protocols (BACnet, Modbus, OPC UA, IEC-61850, MQTT, SNMP, NTP/PTP)
• Lead technical evaluations of controls integrators, network suppliers, and commissioning agents
• Support factory testing, site acceptance testing, failover validation, and integrated systems testing
• Troubleshoot complex OT network issues including packet loss, latency, routing errors, and protocol incompatibilities

What they're looking for

• OT network architecture and design for mission-critical environments
• Layer 2 and Layer 3 network design (routing, VLANs, IP addressing, ACLs, segmentation)
• Industrial redundancy protocols (PRP, HSR, RSTP/MSTP, ring topologies)
• Industrial network equipment (Cisco, Juniper, Palo Alto, Rockwell Stratix, Siemens Ruggedcom)
• Controls systems and industrial automation background
• OT/IT boundary security and firewall policy design
• Network troubleshooting and diagnostics
• Multiple industrial protocols (BACnet, Modbus, OPC UA, IEC-61850, MQTT)
