Role Overview

We are looking for a Senior Network Software Engineer to design and implement next-generation EVPN L2/L3 services over SRv6 using FRRouting (FRR) and the Linux networking stack.

You will work on control-plane extensions (BGP EVPN, ISIS), Linux SRv6 dataplane integration, and cloud-native deployment (Kubernetes). This role involves deep systems programming, close interaction with the Linux kernel, and shaping future open-source networking capabilities.

Key Responsibilities

Control Plane (FRR)

Extend FRR (bgp) to support for EVPN routes with SRv6 L2 Service SIDs
Integrate ISIS SRv6 locators and SID reachability into EVPN resolution logic
Design and implement new ZAPI extensions for SRv6 L2 dataplane control
Contribute to FRR CLI and YANG models for SRv6-based EVPN services

Dataplane (Linux SRv6)

Implement Linux SRv6 dataplane integration for (DT2U / DT2M / DX2 behaviors), SRv6 encapsulation
Integrate EVPN MAC/FDB state with Linux bridges and VLANs
Debug and optimize forwarding behavior in Linux networking stack

Cloud-Native & Platform

Package FRR + SRv6 into containerized deployments
Integrate with RHEL CoreOS
Collaborate on Operator/CRD-driven network service provisioning

Collaboration & Open Source

Participate in architecture/design reviews
Produce high-quality design documentation
Contribute upstream-quality code (FRR, Linux where applicable)
Mentor junior engineers

Required Experience & Skills

Must Have

8+ years in network systems or kernel-adjacent development
Strong C programming skills (production-grade)
Hands-on experience with FRRouting (FRR) on bgpd, zebra, isisd or equivalent routing stack
Deep understanding of BGP EVPN, SRv6, Linux networking stack (netlink, routes, bridges, FDB, VRF)
Experience working with IPv6-only underlays
Proven ability to debug complex distributed systems

Strong Plus
