About the company
Vapi is a Voice AI platform that resolves, not transfers. Powering 1 billion calls for companies like Amazon Ring, Intuit, ServiceTitan, and New York Life. Trusted by 1 million developers. Backed by Peak XV, Bessemer, Kleiner Perkins, M12, Y Combinator, and more with $72M raised.
Responsibilities
- Drive 99.99% call completion.
- Run incident command and own SLOs and error budgets.
- Build reliability culture from scratch.
- Ship code (Go or TypeScript) for services that monitor and manage the platform: auto-remediation, capacity forecasters, oncall tooling.
- Join the oncall rotation within 30 days.
- Walk the 15 stability-gap incidents and turn patterns into a prioritized reliability backlog.
- Define the first set of SLOs for the call-completion path.
- Stand up error budgets and SLO-based alerting in Chronosphere/Prometheus for the highest-impact services within 60 days.
- Run the first proper load test against provider rate limits and per-org concurrency.
- Tune autoscaling for wscaler / workerpool-cron-scaler.
- Ship a real platform service — capacity forecaster, auto-remediation, or oncall tooling — in Go or TypeScript within 90 days.
- Own the postmortem process.
- Drive a measurable improvement in p99 call completion or MTTR.
Requirements
- Must-haves:
- You’ve run incident command and postmortem discipline at scale on a real oncall rotation.
- You’ve operated SLOs and error budgets in Chronosphere, Prometheus, Grafana, or Datadog.
- You’ve done capacity planning and load testing for production systems with real users.
- You’re fluent in Kubernetes production ops: pod crash diagnosis, HPA/VPA tuning, PodDisruptionBudgets, graceful shutdown.
- You know backpressure and autoscaling patterns — KEDA, custom metrics scaling.
- Nice-to-haves:
- You ship code, not just scripts. You can build platform services in Go or TypeScript (matches Vapi’s cluster-manager, database-health, wscaler, incidentManager).
- Real-time / latency-sensitive product background where degraded means a dropped call, not a slow dashboard.
Conditions
- Competitive salary and excellent equity ownership.
- Comprehensive health coverage: medical, dental, and vision plans.
- Quarterly off-sites.
- Flexible time off.
- Catered meals, transportation, gym, and a $10k annual L&D budget.
