- Perform advanced network troubleshooting, including deep packet analysis and the resolution of complex routing, switching, and VPN connectivity issues.
- Configure and maintain network infrastructure involving IPv4, IPv6, dynamic routing protocols, and switching technologies.
- Introduce and develop basic network automation using tools such as Ansible, Python, or Bash to streamline deployments and operational workflows.
- Collaborate with the Security Operations Center (SOC) team to analyze firewall logs, investigate security events, and help mitigate incidents.
- Identify opportunities to improve network configurations, technical designs, security practices, and operational efficiency.
- Train and onboard new colleagues, share technical knowledge, and contribute to the team's professional development.

- Take on additional responsibilities when needed to support colleagues, strengthen team capabilities, and expand technical expertise.
