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, policy traceability, routing event visibility, and operational workflows used in production environments.
Partner with product, platform, and cloud networking teams to ensure alignment with AWS, Azure, and GCP networking primitives including routing boundaries, private connectivity, service routing, and hybrid/cloud edge patterns.
Mentor teams and drive engineering excellence in networking, distributed systems, and cloud-native design.
What You Bring
Strong hands-on experience building networking systems with a focus on routing logic, distributed state management, or networking control-plane development.
Practical experience with one or more advanced networking concepts such as:
route policy frameworks, peering models, routing state machines, L3VPNs, EVPN-style overlays, or distributed topology management.
(Experience may include open-source stacks, commercial routers, SDN controllers, or cloud networking platforms.)
Solid understanding of distributed system fundamentals including eventual consistency, consensus models (e.g., Raft), cluster coordination, and state synchronization patterns is a strong plus
Experience with cloud-native networking (Kubernetes networking, service routing, intent-based networking, or large-scale multi-cloud connectivity models).
Strong Linux fundamentals including namespaces, networking internals, and debugging of runtime behavior in distributed systems.
Proven track record driving architecture, improving platform reliability, and mentoring engineering teams.
Strong analytical and debugging skills, especially in scenarios involving dynamic routing behavior, distributed failures, or configuration-driven networking logic.
Requirements
12+ years of experience in software engineering with a focus on networking control-plane development, distributed networking systems, SDN, or cloud network orchestration.
Bachelor's or Master's Degree in Computer Science, Engineering, or equivalent hands-on industry experience.
The Job Description is intended to be a general representation of the responsibilities and requirements of the job. However, the description may not be all-inclusive, and responsibilities and requirements are subject to change.
