Member of Technical Staff, Site Reliablity Engineer

Why We’re Hiring

This role drives 99.99% call completion. You’ll join the oncall rotation, walk through 15 stability-gap incidents, define the first set of SLOs, and stand up error budgets and SLO-based alerting.

What You’ll Do

• Join the oncall rotation and walk through 15 stability-gap incidents.
• 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.
• 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.
• Own the postmortem process and drive a measurable improvement in p99 call completion or MTTR.

Who You Are

• Must-have: You’ve run incident command and postmortem discipline at scale on a real oncall rotation.
• Must-have: You’ve operated SLOs and error budgets in Chronosphere, Prometheus, Grafana, or Datadog.
• Must-have: You’ve done capacity planning and load testing for production systems with real users.
• Must-have: You’re fluent in Kubernetes production ops: pod crash diagnosis, HPA/VPA tuning, PodDisruptionBudgets, graceful shutdown.
• Must-have: You know backpressure and autoscaling patterns — KEDA, custom metrics scaling.
• Nice-to-have: You ship code, not just scripts. You can build platform services in Go or TypeScript (matches Vapi’s 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.

What We Offer

• Real stake: Competitive salary and excellent equity ownership.
• Comprehensive health coverage: medical, dental, and vision plans.
• Team love: Hanging out and quarterly off-sites.
• Flexible time off: Take what you need.
• More: Catered meals, transportation, gym, and a $10k annual L&D budget.
