* Network Security: Enforce security controls including next-generation firewalls, VPNs (IPsec/SSL), ACLs, network segmentation, and Zero Trust architecture; collaborate closely with Cybersecurity teams on policy and compliance.
* Cloud & Hybrid Networking: Architect and manage SD-WAN, SDN, and NFV solutions; design and support hybrid cloud networking across AWS, Azure, and/or GCP, including connectivity, routing, and security policy enforcement.
* Automation & Infrastructure-as-Code: Automate network provisioning, configuration management, and validation using Ansible, Python, Terraform, and similar tools; integrate with CI/CD pipelines and infrastructure-as-code workflows.
* Network Access Control: Deploy and manage NAC technologies (e.g., Cisco ISE) to enforce endpoint compliance and control access to sensitive network segments.
* Network Management & Assurance: Administer enterprise network management platforms; leverage AI/ML-driven analytics, telemetry, and assurance tooling to proactively monitor performance, identify anomalies, and drive rapid issue resolution.
* Operations & Incident Response: Serve as the Tier 3/4 escalation point for complex network incidents; conduct root cause analysis, capacity planning, lifecycle management, and performance tuning.
* Documentation & Stakeholder Communication: Produce and maintain network designs, architecture diagrams, implementation plans, and change management documentation; deliver technical briefings to both technical and non-technical audiences.
* Mentorship & Standards Development: Mentor junior engineers and contribute to organizational standards, engineering playbooks, and best practices.
