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.
