Position: Senior Software Engineer, Nextunnel (Node Connectivity)
Location: San Jose Remote
At Cisco Meraki, we simplify technology so our customers can focus on what matters to them. The Node Connectivity team builds Nextunnel, the secure connectivity layer between millions of Meraki devices and the cloud services that manage them.
Nextunnel is a globally distributed, high-availability networking system. It routes device traffic across regions while enforcing strict access controls and preserving service through failures. The platform is written primarily in Go and runs on Kubernetes in AWS. It uses gRPC, mTLS, Docker, GitLab CI, Kustomize, and modern observability tooling.
We are looking for a hands-on technical lead to guide porting the system to a new deployment platform.
What you will do
Work on porting Nextunnel deployment to a newly created internal kubernetes-like platform.
Troubleshoot issues in bootstrapping nextunnel in this new environment.
Improve the service's scalability, reliability, security, performance, and operability.
Establish clear technical direction and turn it into practical, staged delivery plans.
Write and review robust Go code for distributed, concurrent, networked systems.
Diagnose complex failures across applications, protocols, containers, and cloud infrastructure.
Strengthen testing through unit, integration, end-to-end, fuzz, and scale tests.
Work with firmware, cloud infrastructure, security, SRE, and product teams on cross-system changes.
What we are looking for
10+ years of professional software engineering experience, including technical leadership of substantial systems.
Strong experience with Go, C/C++, or another systems programming language, with the ability to become productive in Go.
Experience designing and operating large-scale distributed services in production.
Strong knowledge of Linux and networking fundamentals, including IPv4/IPv6, TCP, routing, DNS, and TLS.
Experience with concurrency, performance analysis, debugging, and capacity planning.
Sound judgment in architecture, incident response, and technical tradeoffs.
Clear written and verbal communication. You can align teams without relying on authority.
Useful experience
Kubernetes, AWS/EKS, Docker, Kustomize, and CI/CD systems.
gRPC, Protocol Buffers, mutual TLS, PKI, or network security.
Packet processing, tunneling, VPNs, load balancing, or distributed routing protocols.
OpenTelemetry, Prometheus, Datadog, or production observability at scale.
Fuzz testing, performance testing, and failure testing.
