Job summary

TENARAI TECHNOLOGIES PRIVATE LIMITED in Bengaluru is seeking an experienced networking specialist to design and operate advanced BGP peering, IS-IS, and MPLS for edge networks. The role focuses on scalable routing, route filtering, and peering hygiene across IXPs and private interconnections.

You will handle eBGP configurations, IRR/RPKI validation, and BFD-based peering health, with hands-on work on fiber optics, transceivers, and DWDM concepts.

Qualifications

• Expertise configuring eBGP peering sessions end-to-end.
• Experience with route filtering using prefix-lists, route-maps, AS-PATH.
• Managing IRR/RPKI/ROA validation for routing hygiene.
• Knowledge of IS-IS and MPLS in backbone/edge transport.

Responsibilities

• Configure and maintain BGP/IS-IS/MPLS routing on edge routers.
• Manage IXPs, route servers, and peering types (public/private).
• Implement and monitor prefix-lists, route-maps, and MD5 authentication.
• Coordinate with optical teams on fiber, transceivers, and test gear.

Detailed Job Description:

BGP & Routing Protocols

• Demonstrates expertise in configuring and managing eBGP peering sessions end-to-end, including session establishment, prefix advertisement, and neighbour management on edge routers.
• Implements and maintains route filtering using prefix-lists, route-maps, and AS-PATH filters to ensure only authorised prefixes are accepted and advertised.
• Manages IRR (Internet Routing Registry) objects and RPKI/ROA validation to maintain routing hygiene and prevent route hijacking/leaks.
• Configures max-prefix limits, MD5 authentication, and BFD for reliable and secure peering sessions.
• Uses BGP communities (standard, extended, large) for traffic engineering, controlling inbound/outbound traffic flow, and signalling peer preferences.
• Has working knowledge of IS-IS as an interior gateway protocol and MPLS for backbone/edge transport

Layer 1 Physical & Optical

• Proficient in Fiber-optic technology including single-mode (SMF) and multi-mode (MMF) fiber, connector types (LC, SC, MPO/MTP), and cable management.
• Hands-on experience with optical transceivers SFP+ (10G), SFP28 (25G), QSFP28 (100G), QSFP-DD (400G) including SR, LR, ER, ZR variants and their reach/application.
• Understands optical power levels (Tx/Rx in dBm), link budget calculations, and can interpret light-level readings to diagnose fiber path issues.
• Familiar with optical test equipment (power meters, OTDR) and their use in verifying cross-connect integrity and troubleshooting signal degradation.
• Experience with DWDM concepts for wavelength-based capacity scaling on metro and long-haul links.

Layer 2 / Layer 3 Protocols & Technologies:

• Shows comprehensive understanding of L2/L3 protocols including VLAN configuration (802.1Q trunking), LACP for link aggregation on peering links, LLDP for neighbour discovery, ARP for address resolution, and MAC address
