TL;DR: This is a dream job for a super-deep networking control plane software nerd who’s into routing, open networking, and open source data-planes. If you’re passionate about Linux, networking, and large scale distributed systems and love messing around with routing, networking gear, dataplane software, smartNICs, DPUs, and IPUs, and think like a packet, you will love this. This is not a DevOps, full-stack programming, javascript, or database position. You MUST be a hardcore control plane developer.
- Help us build an Open Network Operating system that people can trust and consume easily.
- Architect, design, and build a scalable high-performance network control plane.
- Fix bugs, and improve/enhance open source routing stacks.
- Work with the Open Source Community, our support organization, and customers to improve user experience and stability of the platform and the features, product issues, and defect detection, identification, and resolution.
The ideal candidate is an experienced software engineer with deep expertise in networking and hardcore real-time and distributed systems programming. This is a hard-core coding position.
This is a hard-core dataplane engineering position. The ideal candidate is an experienced software engineer with deep expertise in networking, routing protocols, and control planes and is well-versed in real-time and distributed systems programming. Must think like a packet.
Prerequisites:
- 7+ years of relevant hardcore routing, control plane, and Linux networking software development/engineering experience..
- We don't care what degree you have; what matters is what you've done and what you can do.
Languages, frameworks, platforms, and tools:
- Experience in programming in at least one of the following languages: C, C++, Rust, or Go.
- Working knowledge and experience with Linux networking
- Experience with open routing stacks, s.a. FRR (previously Quagga, Zebra), Bird, KubeRouter, ExaBGP, FreeRouter, XORP ...
- Experience with routing protocols, s.a. BGP, OSPF, ISIS, RIP, … is a huge plus.
- Experience with overlay technologies like VxLAN, Geneve, ...
- Hands-on experience and familiarity with BGP-based underlays.
- Hands-on experience and familiarity with BGP EVPN
- Working knowledge of network debug, troubleshooting and testing tools.
Network test tools experience requirements (1 or more of the below):
- Use Keysight, IXIA, Spirent, and other traffic generators to characterize the scale and performance.
- Experience with SFLOW, NETFLOW tools, and other network monitoring tools.
- Strong skills in packet decoding, reading pcap files, and analyzing sniffer traces.
Network technology experience requirements (a huge plus):
- Experience with high-performance dataplanes VPP, eBPF, DPDK, or VPP.
- Hands-on experience with SDN goodness like P4, OpenFlow
- Experience with management goodness like OpenConfig, GNMI, NETCONF
- Experience with XDP
- Experience with dataplane acceleration/offload/execution at smartNIC/IPU/DPU. Specifically, NVIDIA Bluefield, Pensando/AMD, Intel, Marvell DPUs/IPUs
- Working knowledge of data-plane debug, troubleshooting and testing tools.
- Familiarity with IPTables, OVS, …
- Familiarity with CNIs like Calico, OVN, Multus, Cillium
Cloud(-native) networking technology experience (a huge plus):
- Hands-on familiarity with Kubernetes networking (Calico, Cilium, etc. CNIs)
- Hands-on familiarity with Service Mesh and API Gateways
- Hands-on familiarity with OpenStack networking (ML2, Neutron)
- Hands-on experience with Wireguard, MetalLB, Traefik, Envoy, etc.
Other requirements:
- Proven experience with cloud, data center, or edge networking products
- Proven experience with debugging customer issues and locally recreating them in the lab
- Strong solution-level exposure to enterprise deployments
- Experience qualifying high-volume, scalable enterprise software
