  • Collaborate with network and systems teams to secure IP / MPLS transport, SDN platforms, automation tools, and cloud workloads.
  • Monitor and analyse security events and alerts, responding to incidents and escalating as appropriate.
  • Assist with vulnerability assessments, patch management validation, and configuration hardening.
  • Document and maintain infrastructure security standards, configurations, and runbooks.
  • Support & Collaboration :

  • Provide input on threat modelling, security testing, and design reviews for internal and external services.
  • Stay current on security threats, tooling, and telecom-relevant vulnerabilities.

  • Familiarity with Linux, scripting (Python, Bash), and infrastructure-as-code concepts.
  • Knowledge of secure configuration standards (e.g., CIS benchmarks) and common protocols (e.g., BGP, DNS, SNMP).
  • Experience supporting or delivering telecom or ISP infrastructure.
