## About the role

30 Day : Ramp on the cell-based architecture, the regional EKS clusters (backend / networking / persistence / monitoring / models / kafka), and the Pulumi stacks. Shadow oncall, walk recent incidents (Envoy response flags, conntrack drops, cross-zone LB target resets), and own a first scoped infra change end-to-end.

## What they're looking for

- You’ve run multi-cluster Kubernetes on EKS in production — backend, networking, persistence, monitoring, models, and kafka clusters per region — and you’ve used Cluster API or similar for programmatic cluster creation
- You’ve operated a stateful data plane (Postgres, Redis, Kafka, Temporal, etcd, ClickHouse) at scale — you’ve sharded it, migrated data between instances, and lived with the consequences
- You’re fluent in Envoy and Cilium/eBPF. You’re comfortable debugging Envoy response flags, conntrack drops, and cross-zone LB behavior. VPC/NAT/Cloudflare alone isn’t enough
- You’ve run multi-region Kafka on MSK in production — not just Kafka. You’ve dealt with regional topic naming, MSK Pulumi drift, and compliance constraints
- You write Go for control-plane services. Vapi’s cluster-manager, traffic-control-plane, and environment-manager are all Go, and you’re comfortable owning code in that stack
- Bonus: SIP / RTP / telephony background. The Nov 7 SIP gateway SPOF is still unsolved, and a telephony-savvy infra hire unblocks that roadmap item
