Confidential search for a Senior Network Security Engineer for a highly respected Chicago organization undergoing a significant modernization of its technology infrastructure.

The ideal candidate is someone who lives at the intersection of enterprise networking and cybersecurity

This is not a GRC, policy or compliance position
. We’re looking for someone who can get into the technology and understand how to build, secure and troubleshoot a large enterprise network.

What You’ll Work With
  • Cisco enterprise networking
  • Enterprise firewalls
  • Network segmentation
  • Routing & switching
  • VLANs / ACLs
  • VPN / secure connectivity
  • IDS / IPS
  • Network Access Control
  • SIEM / security monitoring
  • Vulnerability management
  • Network hardening and security architecture
Ideal Background
  • 5+ years of enterprise network/security engineering
  • Strong firewall experience
  • Strong Cisco networking knowledge
  • Deep understanding of TCP/IP and routing/switching
  • Experience with segmentation and network-security architecture
  • Ability to independently troubleshoot difficult network/security issues
  • Experience in a large, complex enterprise environment
  • Strong communication and documentation skills
  • Healthcare experience is helpful but not required
  • Interested in strong engineers coming from banking, insurance, universities, large corporations or other complex 24x7 environments

This organization is making a major investment in modernizing its infrastructure, creating an opportunity to help build and secure the future-state network rather than simply maintain the old one
.

Important: This is primarily an onsite position in downtown Chicago/Streeterville five days per week
. Candidates should not consider this a remote opportunity.
