Everything we do centers around people. That means we obsess over how to make the lives of our customers, and their customers, better. And it means we prioritize a diverse F5 community where each individual can thrive.

We are looking for a Principal Software Engineer with deep experience in distributed networking systems and routing control-plane development. This role will define and evolve core networking intelligence for our platform — including routing logic, policy orchestration, state synchronization, and multi-cloud connectivity behavior.
You’ll operate as a hands-on technical leader, driving architectural direction, mentoring engineers, and ensuring that our networking control-plane is scalable, resilient,



and operationally transparent across global environments.

What You’ll Do
- Design and develop routing control-plane services, including route computation, convergence handling, topology abstraction, configuration modeling, and distributed reconciliation logic.
- Build and evolve networking intelligence for service-to-service routing, connectivity policies, traffic segmentation, and cross-region/multi-tenant behavior.
- Define system architecture supporting high availability, deterministic failover, scale-out routing state distribution, and consistent configuration propagation across clusters and sites.
- Lead design reviews, influence engineering patterns, and ensure correctness, observability, and operational readiness of networking components.
- Develop testing strategies for route scale, convergence timing, configuration drift, and failure simulation under realistic networking conditions.
- Build tooling for debuggability, polic
