Vapi (/ˈVɑːpi/):

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

• We're the most configurable platform for deploying voice agents.
• 1M+ developers build on Vapi, and we power 1M+ calls a day for companies like Amazon, Intuit, and New York Life.
• We just announced our Series B and are based in San Francisco.

Why We’re Hiring This Role:

• Vapi is the platform enterprises use to build production voice agents, and our product surface is expanding fast to support the next billion calls.
• We're hiring our first dedicated QA Engineer on the product team to own end-to-end quality across that surface.
• This is a real ownership role: you'll work on the cutting edge of AI, define how we test a non-deterministic product, partner directly with engineers on a small team, and have outsized impact on what our customers experience every day.

What You’ll Do:

• First 30 Days:
  • Build and deploy real assistants on Vapi, run live calls and simulations across our main provider integrations (LLMs, STT, TTS, telephony), and break the product in at least a few interesting ways.
  • Get up and running in our existing e2e test framework and ship your first Playwright tests against the dashboard.
  • File bugs that engineers fix, and develop a working point of view on where our coverage is weakest.
• By 60 Days:
  • Own release testing for at least one major product area (assistant builder, simulations, monitoring, knowledge base, or versioning), and earn engineers' trust to gate it.
  • Meaningfully improve automated coverage in your area.
  • Partner with engineers on test strategy for new features before they ship.
  • Use AI coding agents to multiply your throughput on test scenarios and regression coverage.
• By 90 Days:
  • Operate as a full peer to engineers on the team, owning QA across the product surface without handholding.
  • Extend our testing practices and contribute patterns the rest of the team picks up.
  • Be involved in new features from the start, with the automation suite meaningfully larger on your watch.

Who You Are:

Must-Haves

• 5+ years in QA, SDET, Test Engineering, or product engineering with a strong testing focus.
• Hands‑on with at least one modern e2e framework — Playwright preferred; Cypress, Selenium, or equivalent are fine.
• Comfortable reading and writing TypeScript / JavaScript well enough to extend our test suite and file bugs with a hypothesis attached.
• Track record testing complex, distributed systems with real failure modes — APIs, integrations, real-time behavior, anything where "correct" isn't a fixed string.
• Daily use of AI coding agents (Claude Code, Cursor, or similar) with opinions about where they help and where they don't.
• Self‑directed: you read the PR, open the product, and start finding what's broken without waiting for a spec.
• Strong written communication, especially in bug reports and test plans.
• Customer empathy and a bias for action: you ship, you own outcomes, and you care what users actually experience.

Nice-to-Haves

• Background in voice AI, conversational AI, LLM applications, or telephony.
• Experience with LLM evals or testing non-deterministic systems.
• Worked on a developer-facing product — APIs, SDKs, dashboards — where the audience is technical.
• Early‑stage startup experience; comfortable with ambiguity and shifting priorities.
• Open‑source contributions or public writing on testing, evals, or QA practice.

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: 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.

Compensation Range: $180K - $280K
