• Administer enterprise password and secrets-management platforms in alignment with security policies.

Network & Security Support:

• Support and troubleshoot local and remote network connectivity, including VLANs, VPNs, and firewall rules.
• Collaborate with Security Operations for incident response, vulnerability management, and log review.
• Maintain firewall configurations, network documentation, and adherence to compliance frameworks (SOC 2, ISO 27001).
• Implement security hardening, antivirus/EDR deployment, and patching compliance for all managed systems.

Collaboration, Documentation & Support:

• Partner with development, infrastructure, and security teams to ensure smooth deployments and integrations.
• Create and maintain clear technical documentation, SOPs, and knowledge-base articles.
• Participate in on-call rotation and planned maintenance windows to ensure 24×7 system availability.
