You Will:

  • Manage cloud security services like cloud proxy/VPN and XDR platforms for secure access and threat detection.
  • Support PKI infrastructure, including certificate lifecycle management and secure key handling.
  • Operate and monitor cloud network components and integrations, applying Secure Access Service Edge (SASE) principles to protect distributed users and cloud access.
  • Implement and maintain network security controls such as firewalls, IDS/IPS, segmentation strategies, and enforce access control policies (ACLs, NACLs, identity-based segmentation) across hybrid environments.
  • Investigate, contain, and resolve network-based security incidents, and contribute to comprehensive post-incident reviews.
  • Collaborate with network and cloud engineering teams to ensure the secure design and implementation of cloud-native and hybrid solutions.

You Have:

  • Proven experience in information security, cybersecurity operations, or a related field.
  • Hands-on experience with cloud-based security services, network security controls, and incident response.
  • Familiarity with SASE, firewalls, IDS/IPS, PKI infrastructure, and certificate management.
  • Strong analytical and problem-solving skills, with the ability to assess complex security risks and develop effective mitigation strategies.
  • Excellent communication and collaboration abilities.
