System Architect / Principal Engineer - IP Routing and MPLS-TE

Mployee.me; Bengaluru; Vor Ort; INR 600.000 - 1.800.000; Vollzeit

Zusammenfassung

Mployee.me is seeking an experienced network software engineer to lead the architecture of routing, MPLS, VPN, and Segment Routing subsystems for IPv4/IPv6. You will design and implement IGPs (OSPF/IS-IS) and BGP-4/MP-BGP across multiple address families, and develop SR-MPLS/SRv6 with IGP extensions and TI-LFA.

You will mentor engineers and collaborate across routing, MPLS, and data plane teams to ensure carrier-grade reliability.

Qualifikationen

• 10+ years in software engineering with 5+ years focused on routing and MPLS protocol development.
• Deep knowledge of IGP protocols (OSPF/IS-IS) and BGP-4/MP-BGP with hands-on implementation experience.
• Proven expertise in SR-MPLS, SRv6, L3VPN, L2VPN, EVPN architectures.
• Track record shipping production-grade routing and MPLS at carrier-grade scale.

Aufgaben

• Architect routing, MPLS, VPN, and Segment Routing subsystems for IPv4/IPv6.
• Implement IGPs (OSPF v2/v3, IS-IS) and BGP-4/MP-BGP across multiple address families.
• Design MPLS label switching, LDP, RSVP-TE for traffic engineering and EVPN/L3VPN/L2VPN.
• Develop Segment Routing (SR-MPLS, SRv6) with IGP extensions, SR Policy, and TI-LFA.
• Plan for large-scale deployments with sub-second convergence and high reliability (GR, NSR, ISSU, BFD).
• Mentor engineers and drive cross-functional reviews across routing, MPLS, and data plane teams.

Job Summary

Leads the architecture and design of routing and MPLS subsystems for our network operating system, spanning IGP, BGP, and VPN.

Responsibilities

• Architect routing, MPLS, VPN, and Segment Routing subsystems for IPv4/IPv6, compliant with IETF/ISO standards
• Design and implement IGP protocols (OSPF v2/v3, IS-IS) and BGP-4/MP-BGP across multiple address families
• Design and implement MPLS label switching, LDP, and RSVP-TE for traffic engineering, plus L3VPN, L2VPN, and EVPN
• Design and implement Segment Routing (SR-MPLS, SRv6) with IGP extensions, SR Policy, and TI-LFA
• Design for large-scale deployments - millions of routes, thousands of BGP peers - with sub-second convergence and carrier-grade reliability (GR, NSR, ISSU, BFD)
• Mentor engineers, run code and architecture reviews, and drive cross-functional collaboration across routing, MPLS, and data plane teams

Requirements

• 10+ years in software engineering, with 5+ years focused on routing and MPLS protocol development
• Expert knowledge of IGP protocols (OSPF, IS-IS) and BGP-4/MP-BGP with hands-on implementation experience
• Deep understanding of Segment Routing (SR-MPLS, SRv6, SR Policy), L3VPN, L2VPN, and EVPN architectures
• Proven track record shipping production-grade routing and MPLS implementations at carrier-grade scale

Nice to Have

• Open-source routing protocol contributions to community projects
• Segment Routing deployment experience with SR-MPLS or SRv6
• Data center EVPN deployment experience with VXLAN overlays
