Description

Key Responsibilities

- Design, implement, and optimize Forti Gate‑based SD‑WAN (business intent overlays, SLA policies, application steering, local breakout).
- Engineer and maintain Firewall security: zones, objects, policies, NAT (central NAT), UTM profiles, SSL inspection, IPS/DoS policies, logging.
- Plan and deploy site‑to‑site VPNs (route/policy‑based), IPsec HA, and hub‑and‑spoke topologies alongside Internet/MPLS underlays.
- Lead campus switching design: STP/RSTP/MST, VLANs, link aggregation (LACP/Ether Channel), access control, QoS marking, storm control.
- Build L3 segmentation (VRFs), inter‑VLAN routing, and east‑west policies across access/distribution with clear zone models.
- Implement high availability:
Forti Gate A‑P/A‑A clusters, dual‑homed uplinks, first‑hop redundancy (VRRP/HSRP/GLBP as applicable).
- Create and maintain network documentation: HLD/LLD, diagrams, IP addressing, security baselines, SOPs, and migration runbooks.
- Establish monitoring & telemetry: SNMP, Net Flow/IPFIX, Syslog, SOC/SIEM integration; define alerting thresholds & runbooks.
- Drive capacity planning, performance tuning, and proactive lifecycle management (firmware, images, templates).
- Collaborate with security, apps, and infra teams for change planning, DR/BCP, and audit/compliance requirements.
- Contribute to automation (nice‑to‑have):
Ansible/Terraform/Git pipelines for config templates, compliance checks, and push operations.
- Provide Tier‑3/4 escalation support and participate in on‑call as needed.
