About the role
- 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.
Responsibilities
- 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.
- Ship a control-plane improvement in Go and drive a measurable reliability or capacity win.
- 90 Day: Lead a roadmap pillar of the cell-based build-out: a new region, a stateful workload migration, or unblocking the SIP gateway SPOF.
- Operate as the infra owner other teams pull in for design reviews, and set the standards (runbooks, failure-domain modeling, capacity targets) the next infra hires inherit.
- We're building cell-based, multi-region infrastructure to drive 99.99% call completion, and this hire owns the foundation: multi-cluster Kubernetes on EKS, a stateful data plane (Postgres, Redis, Kafka, Temporal, ClickHouse), Envoy/Cilium networking, and multi-region Kafka on MSK across EU and ANZ.
Nice to have
- The Nov 7 SIP gateway SPOF is still unsolved, and a telephony-savvy infra hire unblocks that roadmap item.
- Microservices experience alone isn't the same.
