    Description

    The Role:

    We are seeking an experienced Network Analyst to play a role in a large-scale network segmentation and Zero Trust transformation initiative. This position is responsible for driving end-to-end traffic analysis, segmentation policy strategy, and application onboarding across data centers, global offices, and multi-cloud environments.
    As a member of the team, you will operate with a high degree of autonomy, partnering closely with engineering, cybersecurity, and application teams to enable the transition from flat networks to highly controlled, micro-segmented environments. You will be accountable for ensuring segmentation policies are accurate, scalable, and aligned to business and security objectives.

    Key Responsibilities:
    Design & Architecture Leadership
    • Analysis of complex enterprise network flows to define segmentation and micro segmentation strategies
    • Help drive development and refinement of Zero Trust-aligned segmentation models (application-centric, environment-based, hybrid)
    • Translate business, application, and regulatory requirements into actionable segmentation design inputs
    • Provide thought leadership on segmentation best practices, policy structures, and onboarding strategies
    • Partner with engineering to ensure design intent is accurately implemented across platforms
    Traffic Analysis & Policy Strategy
    • Application dependency mapping and traffic flow analysis across large-scale environments
    • Partner to develop segmentation policy frameworks, including allow/deny models and least-privilege strategies
    • Partner on policy lifecycle: discovery, simulation, validation, and enforcement readiness
    • Identify systemic risks such as over-permissive access, shadow dependencies, and undocumented flows
    • Establish standards for policy quality, reusability, and scalability across the organization
    Implementation Oversight
    • Provide guidance for onboarding applications into segmentation platforms across on-prem and cloud environments
    • Validate alignment across: segmentation platforms, firewalls and ACLs, and cloud-native security controls
    • Ensure consistency between segmentation design, engineering implementation, and operational enforcement
    Operations & Optimization
    • Define and track segmentation effectiveness metrics (policy accuracy, enforcement success, exception rates)
    • Partner to drive continuous improvement of segmentation policy posture and operational processes
    • Identify gaps in visibility, tooling, or automation and recommend strategic enhancements
    Qualifications:

    7–10+ years of experience in:
    • Network/Data analysis, engineering, or network security
    • Enterprise/data center networking environments
    Advanced experience with:
    • Application dependency mapping and traffic flow analysis at scale
    • East-west traffic visibility and segmentation policy design
    Strong familiarity with:
    • Segmentation tools (Illumio, Guardicore/Akamai, Cisco Secure Workload/Tetration)
    • Enterprise networking platforms (Cisco, Arista, Palo Alto, Check Point, Juniper)
    High level understanding of:
    • TCP/IP, routing, and switching
    • Network security principles, firewalls, and access control models
    • Segmentation and Zero Trust architectures
    Experience with:
    • Cloud networking (AWS, Azure, GCP)
    • CMDB and asset inventory systems (e.g., ServiceNow)
    Working knowledge of:
    • Automation/scripting (Python, PowerShell, APIs)
    • Kubernetes/container networking (preferred)
