Description :\n\nKey Responsibilities :\n\nCloud modernization & hybrid connectivity :\n\n- 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.\n\n- Build connectivity between on-premises data centers and cloud landing zones, ensuring performance, redundancy, and secure east-west and north-south traffic flows.\n\n- Codify the network as infrastructure authoring and reviewing Terraform and Ansible so cloud and hybrid network changes are repeatable, versioned, and auditable.\n\nData center consolidation & migration :\n\n- Plan and execute network cutovers for data center consolidation and workload migration discovery, dependency mapping, low-level design, migration runbooks, and rollback plans.\n\n- Lead cutover events including out-of-hours change windows, coordinating validation and hyper-care with application, cloud, and infrastructure teams across sites.\n\n- Refactor and decommission legacy DC network components (routing, switching, firewall rules, load-balancer configs, IP space) as sites are consolidated, retiring technical debt safely.\n\nData center consolidation & migration :\n\n- Plan and execute network cutovers for data center consolidation and workload migration discovery,

consolidated, retiring technical debt safely.\n\nNetwork engineering & operations :\n\n- Design, implement, and operate enterprise routing and switching (BGP, OSPF, VLANs, VXLAN/EVPN), data center fabric (Cisco Nexus/ACI or equivalent), SD-WAN, firewalls, and load balancers.\n\n- Own complex troubleshooting as an escalation point for high-severity and cross-domain network incidents driving root-cause analysis, resolution, and prevention with minimal supervision.\n\n- Strengthen resilience and security through segmentation, zero-trust principles, and hardening consistent with healthcare compliance requirements (e.g., HIPAA, PCI-DSS) and Zelis standards.\n\nObservability, automation & continuous improvement :\n\n- Improve visibility using monitoring and observability tooling (e.g., SolarWinds, ThousandEyes, NetFlow, SNMP, Datadog) with actionable alerting and dashboards.\n\n- Automate recurring work configuration management, compliance checks, and remediation using Python, Ansible, and CI/CD to reduce manual effort and change risk.\n\n- Maintain standards up-to-date designs, runbooks, and diagrams (HLD/LLD) and contribute to network standards, patterns, and best practices.\n\nCollaboration & stakeholder engagement :\n\n- Partner across US and India stakeholders cloud, DevOps, SRE, IT operations, security, and application teams in a matrixed, follow-the-sun model, ensuring smooth handoffs and shared context.\n\n- Drive work independently translating ambiguous requirements into clear plans, sequencing tasks, and delivering to timelines without close oversight.\n\n- Communicate clearly to both technical peers and non-technical stakeholders status, risk, and impact and mentor junior engineers on the team.\n\nQualifications :\n\n- 5+ years of hands-on enterprise network engineering experience, including a senior/lead role on medium-to-large environments.\n\n- Deep, demonstrable expertise in routing and switching BGP, OSPF, VLANs, spanning tree, and multicast with strong fundamentals in TCP/IP, DNS, DHCP, and NAT.\n\n- Proven data center networking experience (Cisco Nexus/ACI, Arista, or equivalent) and hands-on hybrid cloud networking in AWS and/or Azure (VPC/VNet, Transit Gateway/vWAN, Direct Connect/ExpressRoute, VPN, security groups/NSGs).\n\n- Hands-on experience with firewalls (Palo Alto, Cisco Firepower/ASA, or Fortinet), load balancers (F5 or equivalent), and SD-WAN.\n\n- Direct experience delivering data center migration and/or consolidation projects, including cutover planning and execution during change windows.\n\n- Practical network automation skills Python and/or Ansible and working knowledge of infrastructure-as-code (Terraform) and Git-based workflows.\n\n- Strong, independent troubleshooting ability across the network stack, with a structured root-cause approach.\n\n- Excellent written and verbal communication, with a track record of collaborating across geographically distributed (US/India) teams and time zones.\nSkills\nNetwork Infrastructure, Network Architecture, Routing & Switching, BGP, Nexus Network, Cisco, TCP/IP, DNS, Firewall, Palo Alto
