Full job description

Vapi (/ˈVɑːpi/):

  • Voice AI that resolves, not transfers
  • Powering 1 billion calls for companies like Amazon Ring, Intuit, ServiceTitan, and New York Life
  • Trusted by 1 million developers building the future of voice agents
  • Backed by Peak XV, Bessemer, Kleiner Perkins, M12, Y Combinator, and more with $72M raised
  • Try talking to Vapi now! https://vapi.ai/ WHY WE’RE HIRING THIS ROLE:
  • 99.99% call completion is the number this role drives. Vapi runs live phone calls — a p99 spike means callers drop. We’ve had 15 stability-gap outages worth learning from, and we need someone who runs incident command, owns SLOs and error budgets, and builds the reliability culture from scratch.
  • This is not a bash-and-YAML role. You’ll ship code (Go or TypeScript) for services that monitor and manage the platform: auto-remediation, capacity forecasters, oncall tooling. Capacity planning, load testing, and KEDA-based autoscaling for Vapi’s wscaler and workerpool-cron-scaler are on your plate. WHAT YOU’LL DO:
  • 30 Day: Join the oncall rotation. Walk the 15 stability-gap incidents and turn the patterns into a prioritized reliability backlog. Define the first set of SLOs for the call-completion path.
  • 60 Day: Stand up error budgets and SLO-based alerting in Chronosphere/Prometheus for the highest-impact services. Run the first proper load test against provider rate limits and per-org concurrency. Tune autoscaling for wscaler / workerpool-cron-scaler.
  • 90 Day: Ship a real platform service — capacity forecaster, auto-remediation, or oncall tooling — in Go or TypeScript. Own the postmortem process. Drive a measurable improvement in p99 call completion or MTTR. WHO YOU ARE: 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. Tech stack you’ll work in
  • Languages: Go and TypeScript (you ship code, not just scripts), Bash.
  • Observability: Chronosphere, Prometheus, Grafana, Datadog, OpenTelemetry.
  • Orchestration: Kubernetes on EKS — production ops (HPA/VPA tuning, PodDisruptionBudgets, graceful shutdown, pod crash diagnosis).
  • Autoscaling and backpressure: KEDA, custom metrics scaling (matches Vapi’s wscaler and workerpool-cron-scaler).
  • Load testing: script-based load testing, provider rate-limit auditing, per-org concurrency auditing.
  • Vapi services you’ll touch or build: cluster-manager, database-health, wscaler, incidentManager. Where you likely come from
  • A real-time / latency-sensitive product (Discord, Zoom, Mux, Twitch, Twilio, LiveKit, Cloudflare, a trading firm, a gaming backend), or a FAANG SRE / Production Engineer (Google, Uber, Twitter/X, Meta) who misses being hands-on.
  • Weak fit: SRE from analytics or CRM backends where “degraded” means a slow dashboard, not a dropped call. Anyone uncomfortable reading or writing code. WHY VAPI:
  • Generational impact: Build the human interface for every business
  • Ownership culture: 70% of the company are previous founders
  • Kind team: The founders, Jordan and Nikhil, are Canadians
  • Tier-1 Investors: YC, KP seed, Bessemer Series A WHAT WE OFFER:
  • Real stake: We offer a competitive salary and excellent equity ownership
  • Comprehensive health coverage: medical, dental, and vision plans
  • Team love: We love hanging out, and we do quarterly off-sites
  • Flexible time off: take what you need More: catered meals, transportation, gym, and a $10k annual L&D budget
