Member of Technical Staff, Infrastructure

About the role

This role involves running multi-cluster Kubernetes on EKS in production, operating a stateful data plane at scale, and managing multi-region Kafka on MSK. The primary responsibilities include writing Go for control-plane services and leading roadmaps for the cell-based build-out.

Responsibilities

• Ramp on the cell-based architecture, the regional EKS clusters, and the Pulumi stacks.
• Shadow on-call, debug Envoy response flags, conntrack drops, and cross-zone LB target resets.
• Take ownership of one core domain such as multi-region MSK, Postgres/Neon consolidation, or programmatic cluster creation via Cluster API.
• Ship a control-plane improvement in Go and drive a measurable reliability or capacity win.
• Lead a roadmap pillar of the cell-based build-out including a new region, a stateful workload migration, or unblocking the SIP gateway SPOF.
• Operate as the infra owner for other teams and set standards for runbooks, failure-domain modeling, and capacity targets.

Requirements

• Experience running multi-cluster Kubernetes on EKS in production.
• Fluency in Envoy and Cilium/eBPF.
• Comfortable debugging Envoy response flags, conntrack drops, and cross-zone LB behavior.
• Experience operating a stateful data plane (Postgres, Redis, Kafka, Temporal, etcd, ClickHouse) at scale.
• Knowledge of multi-region Kafka on MSK in production.
• Experience with Cluster API or similar for programmatic cluster creation.
• Writing Go for control-plane services in Vapi's cluster-manager, traffic-control-plane, and environment-manager stacks.

Qualifications

• Experience with cell-based architecture and shard management.
• Background in VoIP, SIP, or telephony.
• Experience with microservices or distributed systems.
• Experience with Envoy and Cilium/eBPF.
• Experience with Kubernetes, EKS, and MSK.
• Experience with Postgres, Redis, Kafka, Temporal, and ClickHouse.
• Experience with Pulumi and Cluster API.
