  • Develop test plans and conduct testing of new features, configurations, and solutions prior to production deployment. 
  • Troubleshoot complex network and security-related issues and provide appropriate resolutions. 
  • Conduct technical workshops and product training for customers where required. 
  • Work closely with internal Sales, Engineering, Support and Product teams to ensure successful project delivery and customer satisfaction. 
  • Maintain a professional and customer-focused approach throughout all engagements. 

Qualifications & Experience: 

  • 5–8+ years of experience in IP-based networks, network design, network security, or related professional services roles. 
  • Strong understanding of networking technologies including routing, switching and load balancing. 
  • Strong knowledge of network security technologies including firewalls, VPN, IPS, Anti-Virus and Application Control. 
  • Strong understanding of TCP/IP, network protocols and cybersecurity concepts. 
  • Hands-on experience implementing, migrating, upgrading and optimising enterprise-grade firewall and network security platforms. 
  • Experience working with complex enterprise network environments and centralised security management platforms. 
  • Experience with Windows and Linux operating systems. 
  • Good Linux command-line knowledge would be advantageous. 
  • Experience with virtualised security environments, multi-domain security management and scalable security platforms would be advantageous. 
  • Relevant networking or cybersecurity certifications are preferred. 
  • Experience with scripting and automation tools such as Ansible would be advantageous. 
  • Experience with cloud security and endpoint security solutions would be an advantage. 
  • Strong troubleshooting and analytical skills. 
  • Ability to work independently as well as collaboratively within a team. 
  • Strong customer-facing and post-sales consulting experience.
