• Ability to lead discovery, current-state assessment, architecture-gap analysis, target-state design, design reviews, deployment governance, validation, stabilization, and handover to operations.

• Experience developing and approving HLDs, LLDs, network and security diagrams, traffic and data-flow diagrams, bills of materials, implementation roadmaps, migration strategies, architecture standards, and decision records.

• Strong knowledge of network segmentation, zones, routing, BGP/OSPF, NAT, VPN/IPsec, high availability, resilient design, secure management, DNS, certificates, reverse proxies, and application-delivery dependencies.

• Experience designing security patterns for Site Vault, firewall build and operations, third-party connectivity, Zero Trust, internet ingress/egress, WAF, cloud security, and Secure Connected Shops.

• Experience defining policy governance, firewall-rule assurance, access-control standards, configuration baselines, RBAC, least privilege, segregation of duties, and compliance boundaries.

• Experience reviewing architecture and changes for operational risk, availability, resilience, performance, implementation dependencies, testing, rollback, outage, and maintenance-window requirements.

• Knowledge of AWS and Azure network-security services, load balancers, edge controls, infrastructure as code, SIEM/logging, ServiceNow, CMDB, monitoring, and automation integration.

• Experience supporting incident, problem, vulnerability, change, lifecycle refresh, platform optimization, reliability, and continuous-improvement activities from an architecture perspective.

• Working knowledge of ITAR/export-control, CUI or EC environments, FedRAMP, China data-residency separation, secure administration, audit evidence, and regulated delivery models.

• Relevant certifications such as CISSP, CCNP Security/CCIE Security, PCNSE, Check Point CCSE/CCSM, Zscaler, AWS/Azure Security, TOGAF, or SABSA are preferred.

Roles & Responsibilities

• Own and govern the network-security architecture across assigned secure-network workstreams and global site deployments.

• Lead discovery and assessment of existing physical and logical networks, security platforms, connectivity, traffic flows, remote-access paths, cloud interfaces, operational dependencies, and architecture gaps.

• Define target-state architectures and reusable patterns for Site Vault, firewall platforms, third-party connectivity, Zero Trust, internet ingress/egress, WAF, cloud edge, and Secure Connected Shops.

• Create, review, approve, and maintain HLDs, LLDs, Visio diagrams, traffic-flow diagrams, bills of materials, migration approaches, implementation timelines, standards, and configuration requirements.

• Provide architecture oversight for Check Point, Palo Alto, Cisco, load balancers, Cloudflare WAF, Zscaler, CyberArk, AWS/Azure edge services, Nozomi, SIEM, CMDB, and ITSM integrations as applicable.

• Ensure designs align with approved customer architectures, cybersecurity policies, deployment processes, compliance boundari es, and operational-support requirements.

• Lead or participate in architecture and design reviews, documenting decisions, risks, assumptions, exceptions, dependencies, technical debt, and required remediation actions.

• Review proposed production changes and evaluate security, availability, resilience, performance, dependency, testing, rollback, and maintenance-window risks before implementation.

• Validate implementation against approved designs through configuration review, testing support, evidence checks, cutover assurance, post-implementation review, and as-built documentation.

• Provide cross-tower technical leadership for complex incidents, vulnerabilities, problems, migrations, platform lifecycle activities, and major changes requiring architecture analysis.

• Define reference architectures, guardrails, templates, playbooks, and standardized deployment patterns to support consistent execution across sites and delivery pods.

• Guide operational readiness, monitoring requirements, support-model alignment, knowledge transfer, SOP development, stabilization, and handover to L1/L2/L3 operations.

• Collaborate with network, firewall, cloud, endpoint, identity, application, SOC, OT, site, compliance, service-management, procurement, and vendor stakeholders.

• Identify opportunities for architecture simplification, automation, policy optimization, reliability improvement, and lifecycle modernization while preserving compliance and service continuity.
