Full Job Description
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.

Key Responsibilities

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)
  • Secure integration with cloud and network services


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
  • Private Endpoints and Private Link
  • Azure Firewall, NSGs, and routing strategies
  • DNS architecture and name resolution


Meraki Network Design & Operations
  • Lead the design, deployment, and optimization of Cisco Meraki environments, including:
  • MX (SD-WAN & security appliances)
  • MS (switching)
  • 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.


Resiliency & Buiness Continuity Engineering (CRITICAL)
  • Design and maintain a highly resilient network architecture across Azure, Meraki, on-prem, and SaaS environments:
  • Eliminate single points of failure
  • Implement redundancy across WAN, LAN, wireless, and cloud
  • 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.
