Full Description
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.
- Try talking to Vapi now!
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.
