Vapi (/ˈwɑːpi/):

  • We’re creating the shift to voice as humanity’s default interface.

  • We’re the most configurable platform for deploying voice agents.

  • We’re grown to 400,000 developers in 20 months, adding 2,000+ every day.

  • Try talking to Vapi now!

Why We’re Hiring This Role:

  • As enterprise adoption grows, we need fast, technically credible frontline support to protect uptime and customer trust.
    ● Enterprise customers are deploying complex voice AI systems in production environments where speed and precision matter.
    ● This role ensures issues are triaged, resolved, or escalated cleanly within SLA while strengthening our support infrastructure over time.

What You’ll Do:

  • 30 Day:

    • Learn Vapi’s API surface area, common integration patterns, and production deployment workflows.

    • Shadow ticket triage and begin resolving straightforward L1 issues independently.

    • Understand tiering framework (P0, P1, P2) and SLA expectations.

    • Familiarize yourself with documentation gaps and internal runbooks.

  • 60 Day:

    • Own front-line enterprise ticket triage with a focus on resolving most tickets within 30 minutes.

    • Apply severity-based prioritization and escalate cleanly when required with full reproduction context.

    • Partner with Deployment Strategists to identify recurring issues and customer health risks.

    • Begin contributing to internal knowledge base and runbooks.

  • 90 Day:

    • Achieve strong L1 resolution rate (70%+) with consistent SLA adherence.

    • Actively improve support workflows, automation triggers, and routing logic.

    • Contribute to SLA automation initiatives (Tasker, Slack bots, routing improvements).

    • Strengthen documentation to reduce repeat issues and increase team velocity.

Who You Are:

  • 4+ years in technical support, support engineering, or customer-facing technical roles at a SaaS or API-first company.

  • Strong troubleshooting ability with REST APIs, JSON payloads, webhooks, and configuration debugging.

  • Comfortable reading API error responses, tracing webhook flows, and diagnosing issues without writing production code.

  • Experience managing SLA-bound queues in systems like Zendesk, Intercom, or Jira Service Management.

  • Clear communicator who can explain technical root causes to customers without unnecessary jargon.

  • Highly organized with strong documentation habits and thorough ticket hygiene.

  • Comfortable in fast-paced environments where enterprise production systems are at stake.

  • Bonus: Experience with voice/telephony systems (SIP, WebRTC, Twilio, Vonage), AI agents, LLMs, or basic scripting for debugging.

Why Vapi:

  • Generational impact: Build human interface for every business.

  • Ownership culture: 90% of company is 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 competitive salary and excellent equity ownership.

  • Comprehensive health coverage: medical, dental, and vision plans.

  • Team love: We love hanging out and do quarterly offsites.

  • Flexible time off: take what you need.

  • More: catered meals and transportation, gym & coaching stipends!
