Join our Team
WAN & Data Center Network Engineer - Juniper
About this opportunity:
Based in Bangalore, you will own implementations and advanced troubleshooting in Juniper-based Service Provider routing environments and EVPN-VXLAN Data Center networks. You will act as a senior escalation point for incidents, problem resolution, and technical operations, and you will lead infrastructure projects end to end. This is a hands-on engineering role in a WAN and Data Center core team, focused on design, implementation, and advanced troubleshooting rather than first- or second-line support. Flexibility for planned work outside office hours is required, and openness to a 24x7 rotation is a plus.
What you will do:• Lead implementation projects from design through delivery, independently.• Implement standardized solutions and adapt non-standard designs across Service Provider WAN and EVPN-VXLAN Data Center networks.• Investigate, diagnose, and resolve complex incidents and recurring problems.• Create and execute MOPs (Methods of Procedure) for infrastructure changes.• Configure and operate Juniper MX, QFX, EX, and SRX devices.• Execute site build-outs, technology refreshes, and migrations across WAN and Data Center environments.• Model network environments in an SSoT tool (e.g. NetBox) as a foundation for automation.• Partner with the NOC/L1 team and the Architecture team, closing the feedback loop between operations and design.
The skills you bring:• 8+ years in WAN and Data Center networking, with strong Service Provider routing experience.• Deep, hands-on expertise with EVPN-VXLAN and modern Data Center architectures (leaf-spine, multi-homing, ESI-LAG, LACP).• Proven ability to design, operate, and troubleshoot core routing and switching at scale - BGP, OSPF, IS-IS, MPLS, and L2/L3 VPN services.• Proven project implementation, troubleshooting, and operations experience.• SRX and/or Palo Alto firewall troubleshooting and security fundamentals.• Solid Linux systems background.• Professional-level certification (Juniper or Cisco) in Data Center and/or Service Provider routing and switching.• Working knowledge of Infrastructure as Code, with hands-on experience in NetBox, AWX/Ansible, or equivalent.• Coding/scripting ability (e.g. Python) is a strong plus, not a requirement.
Note: All academic credentials must be from recognized and accredited institutions and are subject to verification.
