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

• Experience with Linux SRv6 or MPLS dataplanes

• Exposure to kernel networking code

• Familiarity with YANG / Netconf / RESTCONF

• Experience with OpenShift / Kubernetes networking
