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.
