The Catalyst SD-WAN Control Plane team builds and maintains the software that keeps the management and control layer of Cisco's SD-WAN solution working end-to-end—secure sessions between WAN edge devices and the controllers/management plane, orchestration and discovery, certificate-backed identity, and the protocol and state-machine logic that must stay reliable at scale across diverse customer networks. You do not need prior SD-WAN experience; we will help you learn the domain. Your job is to bring strong systems and networking fundamentals and ship high-quality, secure, operable software.

You will own meaningful slices of work in the control plane—design, implementation, testing, and follow-through into production—partnering with teammates and adjacent teams to get to the right solution. Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field plus 5 years of relevant experience, or Master's degree in a related field plus 3 years of relevant experience.

Strong software development background in C/C++ or comparable systems languages used in performance-sensitive networking software.

Solid networking fundamentals: Experience building production-grade software: testing discipline, performance awareness, failure handling, and ownership through maintenance and customer-driven issues.

Experience with WAN edge, VPN, or overlay networking products (IPsec/SSL VPN, DMVPN, MPLS L3VPN, EVPN, or similar)—transferable to SD-WAN even if you have not used SD-WAN before.

Familiarity with distributed systems patterns: long-lived connections, reconnect/backoff, state machines, idempotency, backoff under load, and observability (logs, metrics, tracing).

Background in security-sensitive networking: Comfort with Linux networking stacks, concurrency, and debugging in multi-threaded or event-driven architectures.
