  • Monitor network performance, uptime, and traffic configurations to optimize bandwidth and prevent system downtime.

  • Implement and enforce strict network security protocols, firewalls, access controls, and data encryption standards to safeguard sensitive financial information.

  • Technical Proficiency: Strong expertise in routing and switching protocols, LAN/WAN setup, VLAN configurations, and managing next-generation firewalls (e.g., Fortinet, Cisco, or Sophos).

  • Certifications: Professional certifications such as CCNA, CCNP, or equivalent network security credentials are highly advantageous.

  • Availability: This is a full-time, 100% onsite role based at the head office in Colombo, requiring the ability to provide on-call support for critical infrastructure maintenance outside standard hours when necessary.

  • Problem-Solving & Communication: Sharp analytical skills to troubleshoot complex network bottlenecks rapidly, combined with clear English communication skills for documentation and cross-team collaboration.

 

What We Offer

  • Financial Sector Exposure: Gain invaluable experience managing high-security, high-availability corporate network infrastructure within a premier financial giant.

  • Hands-On Technical Growth: Direct involvement in scaling and securing enterprise-grade network hardware and security firewalls.
