We are seeking a Lead/Senior Security System Engineer to design, implement, and operate secure, compliant network segmentation between regional environments and Global networks, using a standardised control stack of Check Point Security Gateways, Palo Alto Networks next-generation firewalls, Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), and Cloudflare for DDoS mitigation, WAF, and application protection. This role blends architecture, hands-on engineering, automation, and L3/L4 operational leadership to deliver policy-driven connectivity under strict regulatory and operational requirements.

Responsibilities

Define trust zones, routing boundaries, and inter-zone controls for regional and Global Network, covering north-south and east-west paths, micro-segmentation for sensitive tiers, and explicit cross-border allow-lists
Produce HLD/LLD, threat models, and control mappings aligned to internal standards and regional regulation to enable secure communication
Design and operate dual-vendor firewall perimeters, with clear control allocation, HA/cluster design, deterministic failover, NAT domain strategy, and SSL/TLS inspection governance tuned for jurisdiction
Engineer ZIA for identity-aware egress controls, SSL inspection with jurisdiction-aware bypasses, inline CASB/DLP, and sanctioned SaaS governance
Implement ZPA for per-application zero-trust access, with connector placement, posture checks, conditional access, and app segmentation replacing legacy VPN where feasible
Design and deliver Site-to-Site VPN, Cloud Interconnect/Partner Interconnect equivalents, and dual-tunnel HA per site with BGP for failover between on-prem and hub VPC
Deploy Cloudflare Magic Transit/Magic WAN, WAF Management, and rate limiting for internet-facing services, with layered defence integration with on-prem perimeters
Engineer SD-WAN/MPLS/SASE paths with policy-based routing, strong encryption, and defined key custody/rotation by jurisdiction
Translate regulatory and internal control requirements into enforceable technical controls for logging, data residency, TLS inspection scope, and lawful intercept considerations
Normalise telemetry from security platforms into SIEM with regional data handling rules, and build detections for cross-border anomalies, DDoS events, and policy drift
Lead L3/L4 incidents, coordinate issue containment, and drive RCAs with corrective actions codified
Manage firewall, Zscaler, and Cloudflare policy through automation tools and vendor APIs, with CI/CD implementation including policy linting, unit tests, and path simulation

Requirements

6-15 years of overall IT experience, with a strong background in network security architecture and engineering
Expertise in Check Point Security Gateways, Palo Alto Networks next-generation firewalls, and firewall cluster/HA design
Proficiency in Zscaler Internet Access and Zscaler Private Access for zero-trust and identity-aware access control
Knowledge of Cloudflare Magic Transit, Magic WAN, and WAF for DDoS mitigation and application protection
Familiarity with cloud hybrid connectivity, including Site-to-Site VPN, Cloud Interconnect, and BGP routing
Understanding of SD-WAN, MPLS, and SASE architectures with policy-based routing and strong encryption protocols
Skills in Microsoft Sentinel and SIEM platforms for telemetry normalisation, detection engineering, and incident response
Competency in automation and policy-as-code using Terraform, Ansible, and vendor REST APIs
Qualifications in regulatory compliance and audit readiness, including control matrices and CIS Benchmarks
