Position Overview

Zelis is modernizing its infrastructure estate — migrating workloads to AWS and Azure, consolidating data centers, and re-platforming the network for a cloud-first, high-availability future. We are hiring a Senior Network Engineer in Hyderabad to help lead this transformation from the ground up: designing and operating resilient network architectures across on-premises data centers and hybrid cloud, executing complex migration and consolidation cutovers, and keeping a healthcare-grade environment secure, observable, and always on.
This is a hands-on senior role for an engineer who can own technically demanding work end to end — architecture through troubleshooting — drive it independently to closure, and partner closely with stakeholders across both the US and India organizations in a matrixed, follow-the-sun operating model.

Key Responsibilities:

Cloud modernization & hybrid connectivity

• Design and deliver hybrid and cloud network architectures across AWS and Azure — VPC/VNet design, Transit Gateway/Virtual WAN, Direct Connect/ExpressRoute, VPN, DNS, and segmentation — aligned to the cloud modernization roadmap.

• Build connectivity between on-premises data centers and cloud landing zones, ensuring performance, redundancy, and secure east-west and north-south traffic flows.

• Codify the network as infrastructure — authoring and reviewing Terraform and Ansible so cloud and hybrid network changes are repeatable, versioned, and auditable.

Data center consolidation & migration

• Plan and execute network cutovers for data center consolidation and workload migration — discovery, dependency mapping, low-level design, migration runbooks, and rollback plans.

• Lead cutover events including out-of-hours change windows, coordinating validation and hyper-care with application, cloud, and infrastructure teams across sites.

• Refactor and decommission legacy DC network components (routing, switching, firewall rules, load-balancer configs, IP space) as sites are consolidated, retiring technical debt safely.
