Roles & Responsibilities

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.

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.

Good to have skills:

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.
