Senior Network Engineer

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.

Network engineering & operations

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.

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.

Strengthen resilience and security through segmentation, zero-trust principles, and hardening consistent with healthcare compliance requirements (e.g., HIPAA, PCI-DSS) and Zelis standards.

Observability, automation & continuous improvement

Improve visibility using monitoring and observability tooling (e.g., SolarWinds, ThousandEyes, NetFlow, SNMP, Datadog) with actionable alerting and dashboards.

Automate recurring work — configuration management, compliance checks, and remediation — using Python, Ansible, and CI/CD to reduce manual effort and change risk.

Maintain standards — up-to-date designs, runbooks, and diagrams (HLD/LLD) — and contribute to network standards, patterns, and best practices.

Collaboration & stakeholder engagement

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.

Drive work independently translating ambiguous requirements into clear plans, sequencing tasks, and delivering to timelines without close oversight.

Communicate clearly to both technical peers and non-technical stakeholders — status, risk, and impact — and mentor junior engineers on the team.

Ownership & drive — takes tasks to closure independently and proactively removes blockers.

Technical depth & troubleshooting — strong first-principles problem solving under pressure.

Collaboration — builds trust and works effectively across a US–India matrix.

Clear communication — concise, accurate, and audience-aware.

Continuous improvement — automates, documents, and raises the standard of the environment.

Education: Bachelor’s degree in Computer Science, Information Technology, Electronics/Communications, or a related field

Location & model: Hyderabad, India; hybrid with sustained overlap into US business hours to support the follow-the-sun operating model.

On-call: Participation in an on-call/change-window rotation for high-severity incidents and planned migration/cutover events.
