Network Security Specialist

We're looking for a Network Security Specialist to manage and evolve our firewall and network security estate, primarily built on Check Point and Cisco platforms. This role sits at the intersection of network engineering and security.  You'll be hands-on with policy management, troubleshooting, and architecture, while working closely with our Infosec Manager on broader security initiatives. This is not a strict Information Security role - we're prioritizing strong technical depth in firewalling and networking over formal InfoSec credentials. If you're a network engineer with serious firewall chops, we want to hear from you.

  Assist with audits and compliance requirements relating to network security controls

  Solid hands-on experience with Check Point firewall management (CCSA/CCSE certification a plus)

  Strong working knowledge of Cisco networking (routing, switching, VPN); CCNA/CCNP a plus

  Comfortable working in a fast-paced, hands-on environment

• Exposure to other firewall/security vendors (Fortinet, Palo Alto)

• Scripting/automation experience (Python, Ansible) for network tasks
