Job description

We are seeking an experienced, delivery-focused Senior Network Operations Engineer Data Center / EVPN / VXLAN for a full-time, long-term contractual engagement based onsite at our Bengaluru, Karnataka facility.

In this role, you will lead the technical execution of Point of Presence (PoP) buildouts, large-scale data center-to-PoP migrations, and high-capacity carrier transport deployments. Acting as a technical authority during scheduled change windows, you will ensure high availability, architectural compliance, and zero unplanned downtime across complex multi-vendor fabric environments.

Primary Responsibilities

• Infrastructure & PoP Builds: Direct the end-to-end commissioning, validation, and go-live phases of enterprise PoP installations, multi-site interconnects, and data center migrations.
• Architecture & Standards Governance: Author, audit, and maintain production-grade High-Level Designs (HLD), Low-Level Designs (LLD), and Methods of Procedure (MOP) to standardize operational readiness.
• Source of Truth Management: Maintain data integrity across the network fabric by establishing baseline configurations, circuit inventories, and IP schemes within Nautobot and DCIM toolsets.
• Carrier & Vendor Management: Coordinate with Tier-1 telecommunications carriers and hardware vendors to supervise high-bandwidth circuit acceptance, optical delivery, cross-connect provisioning, and link SLA sign-offs.
• Change Execution & Operational Resilience: Lead complex routing cutovers, device refreshes, and firmware lifecycle management during assigned rotational night shifts and maintenance windows.

Required Qualifications & Technical Acumen

• Industry Experience: Minimum of 8+ years of progressive experience in enterprise network engineering, operations, or large-scale data center environments.
• Fabric & Overlay Architecture: Advanced hands‑on implementation and operational depth in EVPN, VXLAN, MP-BGP, and VRF-lite/multi-tenant topologies.
• Core Routing Protocols: Expert‑level understanding of dynamic IP routing protocols, including BGP (eBGP/iBGP), OSPF, IS-IS, and EIGRP.
• Transport & WAN Engineering: Strong practical knowledge of transport architectures including Segment Routing (SR-TE), MPLS (L2/L3VPN), DWDM optical interfaces, and DMVPN.
• Multi-Vendor Network OS: Advanced operational and CLI configuration experience across Arista EOS, Cisco (NX-OS, IOS-XR, IOS-XE), and Linux-based platforms (e.g., Cumulus).
• Operational Availability: Demonstrated flexibility and readiness to support rotational schedules, night shifts, and off-hours maintenance cutovers.

Preferred Credentials

• Cisco Certified Internetwork Expert (CCIE Data Center, Enterprise, or Service Provider) or equivalent industry certification (e.g., JNCIE, Arista ACE).
• Working familiarity with API-driven network automation workflows (Python, Ansible, Jinja2) leveraging Nautobot or NetBox.
