The Sr. Network Engineer & Connectivity Architect serves as the principal architect of the organization’s enterprise connectivity platform (The Backbone), with a primary focus on Microsoft Azure networking, Cisco Meraki infrastructure, and identity-driven access (Active Directory & Entra ID).

This role is responsible for designing and operating a secure, highly resilient, and cloud-aligned network architecture, where access decisions are governed by user identity, device posture, and real-time risk signals, rather than traditional network boundaries. Leveraging Infrastructure as Code (IaC), AIOps, and Zero Trust principles, this position ensures seamless, secure connectivity across Azure, on-prem environments, branch networks (Meraki), and SaaS platforms such as Microsoft 365, while enabling a scalable, automated, and self-healing infrastructure.

• Identity-Driven Network Architecture (CORE)
  Design and implement a network architecture where identity is the primary control plane. Integrate Active Directory (on-prem), Entra ID, and identity providers (Okta) with network enforcement points to enable real-time, identity-based access decisions.
• Active Directory & Hybrid Identity Ownership
  Architect and support enterprise-scale hybrid identity environments, including:
• Active Directory design (sites, replication, GPO strategy)
• Entra Connect (Azure AD Connect) synchronization
• Authentication protocols (Kerberos, NTLM, modern authentication)

• Entra ID & Conditional Access Engineering
  Design, implement, and optimize Conditional Access policies, including:
• MFA enforcement strategies
• Device compliance (Intune integration)
• Risk-based and session-based access controls
• Location-aware and Zero Trust access models
• Zero Trust & Identity Enforcement
  Lead the implementation of a Zero Trust architecture by aligning:
• Identity (Entra ID / Active Directory / Okta)
• Network (Azure, Meraki)
• Endpoint (Intune / device posture)
• Ensure consistent enforcement of least privilege access across all environments.
• Microsoft 365 Identity & Access Optimization
  Ensure secure, high-performance access to Microsoft 365 by:
• Aligning identity policies with network routing and access controls
• Supporting modern authentication flows and token-based access
• Optimizing Teams, Exchange, and SharePoint connectivity
• Azure-Centric Network Architecture
  Design and implement scalable Azure networking solutions, including:
• Virtual Networks (VNet) and Hub-and-Spoke architectures

• MR (wireless)
• Auto VPN and centralized cloud-based management
• Hybrid Connectivity & Interconnects
  Architect and manage secure connectivity between environments using:
• ExpressRoute
• VPN Gateways
• Meraki SD-WAN (Auto VPN)
• Ensure low latency, high availability, and seamless failover.
• Infrastructure as Code (IaC) & Automation
  Manage network and cloud configurations as code using:
• Terraform, Bicep, or ARM templates
• CI/CD pipelines (Azure DevOps, GitHub Actions)
• Ensure all deployments are standardized, repeatable, and auditable.
• AI Ops & Observability
  Implement monitoring and telemetry across Azure and Meraki using:
• Azure Monitor & Log Analytics
• Meraki Dashboard
• Observability tools (Dynatrace, Splunk, etc.)
• Enable proactive detection, anomaly identification, and automated remediation.

• Design for automated failover and rapid recovery
• Ensure identity-dependent services remain available during outages
• Governance & Policy Enforcement
  Establish and enforce governance using:
• Azure Policy and tagging standards
• Policy-as-Code frameworks
• Identity governance (access reviews, RBAC, least privilege)
• Ensure compliance with security, regulatory, and enterprise standards.

• Identity & Access (PRIMARY)
  Deep expertise in Active Directory (architecture, GPOs, replication), Entra ID, Conditional Access, MFA, federation (SAML, OAuth, OIDC), hybrid identity
• Zero Trust Architecture
  Experience implementing identity-driven access integrating network, endpoint, and SaaS
