We're hiring a Senior Firewall / Security Network Engineer to own the design, delivery, and operation of our firewall and network-security estate across on-prem data centers and cloud (AWS, OCI). This is a hands-on senior role: you'll set the firewall architecture — especially for hybrid and cloud connectivity — while running the day-to-day change and incident work that keeps the business connected and secure. You'll be the technical anchor as we migrate a multi-vendor estate onto a standardized FortiGate platform and build the cloud security layer our AWS migration depends on.
What you'll do
Cloud & hybrid firewall architecture
Design and deliver the firewall/security layer for cloud and hybrid connectivity — AWS (Transit Gateway, VPC, GWLB), OCI, and on-prem↔cloud traffic flows.
Own route/prefix and policy design across the boundary so cloud workloads reach on-prem services (and vice versa) securely and without becoming snowflakes.
Partner with the security operations, cloud and platform teams to make the security design a first-class part of migration planning, not an afterthought.
Firewall policy engineering & change management
Translate connectivity requests from application, database, and cloud teams into clean, standards-based firewall policy (allow/NAT/port/service rules, TLS flows).
Drive changes through the RP change-management process — with clear implementation, testing, and rollback plans — and peer-review others' changes.
Keep policy consistent and auditable across sites; retire one-off exceptions. Migration & platform lifecycle
Lead migrations from legacy Cisco and Juniper to FortiGate , including policy review, rebuild, and cutover.
Plan and execute quarterly firewall software upgrades and hardware refreshes with minimal disruption.
Manage IPsec/site-to-site migrations and firewall decommissioning.
Operations, incident response & availability
Triage and resolve connectivity incidents — blocked/dropped traffic, TLS handshake failures, VPN outages, firewall failovers.
Own the out-of-band (OOB) management network for firewalls: reachability, console access, and monitoring enablement.
Observability, logging & compliance
Integrate firewalls with logging and monitoring — FortiAnalyzer, SIEM log forwarding, netflow, SNMP.
Help close misconfiguration and risk findings
Required qualifications
Hands-on FortiGate / FortiOS expertise: VDOMs, security policy, NAT, SSL inspection, FortiAnalyzer, and FortiConverter.
Cloud network security: firewall/connectivity design in AWS (TGW, VPC, GWLB) and/or OCI, including hybrid on-prem↔cloud flows..
Disciplined change management: implementation, testing, and rollback planning, plus peer review.
Strong connectivity troubleshooting across the packet path (drops, TLS, DNS, routing).
Ability to work directly with application, database, cloud, and security teams to turn requirements into secure, standardized policy.
Preferred / nice-to-have
Experience using AI services/assistants in an engineering workflow — AI-assisted troubleshooting, config generation, or building tooling and automation around network/security systems (e.g. API-driven agents, MCP servers)
Network automation — Ansible, AWX, or similar — for config and policy management.
SIEM / observability tooling (FortiAnalyzer, netflow, SNMP, log pipelines).
Multi-site WAN and data-center networking experience.
Scripting (Python or similar) for tooling and validation.
Exposure to security frameworks and audit/misconfiguration remediation.
How the role works
High cross-functional surface: application/DB/cloud teams (connectivity requests), SecOps and the broader security org (risk sign-off, shared initiatives), and site/infra teams (builds and migrations). - Work is tracked and delivered through the team's change process
