This critical role is:

✔️ responsible for assuring the security posture of our network infrastructure,

❗️ You will not simply help implement security measures, but will oversee their effectiveness, proactively identify vulnerabilities, and guide the implementation of best practices

This role bridges the gap between traditional network engineering and cyber security, ensuring our network is a robust defense against evolving threats. 

You will collaborate closely with the networking and IT teams, providing security guidance, performing risk assessments, and helping to respond to security incidents related to network infrastructure.


Key Responsibilities:

  • Network Security Oversight – Be the primary security advisor to the Network team, ensuring security is integrated into all network designs, deployments, and changes.

  • Network Segmentation – Advise on the design and implementation of network segmentation strategies that will help to isolate critical systems and limit the impact of potential breaches.

  • VPN and Remote Access Security – Advise on the design and implementation of our VPN solution, ensuring secure connectivity for employees and 3rd party consultants.

  • Network Security Policies – Develop, document, and enforce network security policies, standards, and procedures

  • Documentation - Maintain comprehensive documentation of network security configurations, procedures, and incident response plans.

  • Collaboration - Work closely with other Cyber Security team members to share knowledge to help improve the overall Security posture of the company.


What You Need to Succeed:

  • Minimum of 5 years of progressive experience in network security engineering, with at least 3-5 years specifically focused on designing, implementing, and managing security solutions in an enterprise environment.

  • Hands-on experience with other network security tools such as IDS/IPS, SIEM, NAC, VPN concentrators, and cloud security gateways is highly desirable.

  • Excellent analytical and problem-solving skills, with the ability to diagnose and resolve complex technical issues under pressure.

  • Strong communication and interpersonal skills, capable of effectively articulating technical concepts to both technical and non-technical stakeholders.

  • Ability to work independently, manage multiple priorities, and lead projects in a fast-paced, dynamic environment.

  • Ability to provide support and collaborate effectively across multiple time zones, adapting to diverse operational hours.

  • In-depth understanding of networking protocols (TCP/IP, DNS, DHCP, Routing, Switching).

  • Familiarity with network monitoring and analysis tools (Wireshark, SolarWinds).

  • Knowledge of regulatory compliance frameworks (NIST, ISO 27001, PCI DSS).

  • Experience with Zero Trust Network Access principles and implementations.

That will be your additional asset: 

  • Cisco Meraki knowledge.

  • Technical skills in Fortinet:

    • Fortinet FortiGate firewalls, advanced routing, NAT, multi-VDOM environments, VPNs (IPSec/SSL), and security profiles (IPS, Application Control, Web Filtering, Antivirus),
