Network Architect

Overview:

The Network Architect will be responsible for designing, integrating, and securing network environments required to support large-scale application migration initiatives. The role involves network architecture design, firewall configuration, integration discussions with cross-functional teams, and ensuring end-to-end connectivity for on-prem and cloud-based workloads.

Key Responsibilities:

  • Lead network architecture and integration discussions to define connectivity requirements for application migration projects.
  • Design and implement network topologies, routing strategies, and segmentation models to support new and existing application environments.
  • Perform and coordinate firewall (FW) changes, including rule creation, optimization, NAT, ACL updates, security policies, and migration of firewall policies.
  • Ensure secure and reliable network connectivity between on-premises data centers, cloud platforms, and third-party applications.
  • Work closely with application, cloud, and security teams to validate network requirements and ensure compatibility with migration workflows.
  • Troubleshoot network performance, latency, routing, DNS, load balancers, and connectivity issues affecting migrated applications.
  • Support end-to-end network readiness, including testing, packet tracing, and validation of communication paths prior to go-live.
  • Maintain documentation for network designs, IP schemas, firewall rule sets, and migration-related architecture changes.
  • Ensure compliance with network security best practices, including traffic segmentation, Zero Trust principles, and access control.
  • Participate in change management (CAB) to evaluate and implement network-related changes with minimal risk.

Required Skills & Experience:

  • Strong experience in network architecture, design, and operations in enterprise environments.
  • Hands-on expertise with firewalls (Palo Alto, Check Point, Fortinet, Cisco ASA, or similar).
  • Solid understanding of routing, switching, VPN, BGP, OSPF, MPLS, and network segmentation.
  • Experience supporting application migrations across data centers or cloud platforms (Azure, AWS, GCP preferred).
  • Strong knowledge of load balancers, proxy servers, DNS, DHCP, NAT, and IP addressing.
  • Ability to interpret and design network diagrams, HLD/LLD documentation, and security architectures.
  • Excellent troubleshooting and communication skills for working with cross-functional teams.

Preferred Qualifications:

  • Relevant certifications such as CCNP, CCIE, PCNSE, NSE, or AWS/Azure Network certifications.
  • Experience with cloud networking (Azure Virtual Network, ExpressRoute, AWS VPC, Transit Gateway, etc.).
  • Familiarity with automation tools (Ansible, Terraform, PowerShell, Python) for network configuration.
