Job summary

Ericsson Bangalore is seeking a WAN & Data Center Network Engineer with Juniper expertise to own design, implementation and advanced troubleshooting in Service Provider routing and EVPN-VXLAN DC networks. This hands-on role focuses on core routing/switching, not routine support, with on-call rotation possible.

You will lead end-to-end projects, create MOPs, configure Juniper MX/QFX/EX/SRX, and collaborate with NOC and Architecture teams.

Qualifications

• 8+ years in WAN and Data Center networking.
• 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.

Responsibilities

• 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.

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.
