Pay and Benefits

Salary: USD 218,000 - 252,000 annually

Key Requirements

  • •Secure production networks at scale and comfortably read packet captures.
  • •Design segmentation for environments mixing IT, OT, and high-value compute.
  • •Deploy and tune NDR or flow-based detection that found real intrusions.
  • •Use infrastructure-as-code practices so firewall rules live in a repo, not a GUI.
  • •Partner with network engineering effectively without blocking progress.
