About the role

Key responsibilities & impact

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.
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.
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.

Requirements

What you’ll need

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.

Benefits

Comp & perks

Comprehensive health coverage: medical, dental, and vision plans.
Flexible time off: take what you need.
Catered meals, transportation, gym, and a $10k annual L&D budget.
Team love: We love hanging out, and we do quarterly off-sites.
