## Description

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., 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
