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.
