Vapi runs a voice-agent platform built on WebRTC and Twilio, with Genesys and Five9 in the stack pointing to integrations with enterprise contact-center systems. Its infrastructure is cloud-native and mature: Kubernetes on AWS EKS, GitOps via Argo CD, Terraform and Pulumi, and deep observability, with Kafka now being adopted. Hiring tilts heavily toward senior sales roles, and job posts center on enterprise post-sales, deployments and partner channels.
