Security Engineer, Network

Fluidstack is focused on delivering significant compute resources for AI infrastructure and is seeking a Security Engineer for their network security team. The role involves designing and defending network security architecture and building a comprehensive security program from scratch.

Responsibilities:

• Design and defend the network security architecture across data centers, corp, and cloud: segmentation, firewalls, and east-west controls at gigawatt scale
• Build network detection: telemetry, flow analysis, and alerting across training fabrics, OT networks, and the WAN
• Harden the OT and BMS side, where the network touches physical plant, against threats most security teams never see
• Automate network security controls so new sites inherit the architecture on day one

Requirements:

• You've secured production networks at scale, and you read a packet capture as comfortably as a dashboard
• You've designed segmentation for environments that mix IT, OT, and high-value compute
• You've deployed and tuned NDR or flow-based detection that found real intrusions
• You work infrastructure-as-code: your firewall rules live in a repo, not a GUI
• You've partnered with network engineering without becoming the department of no
• OT and ICS security
• Data center or cloud provider environments
• BGP and routing security
• Zeek or Suricata
