Skill guide

What to know about Jest

Jest is a JavaScript testing framework, created at Meta, with built-in assertions, mocking, snapshot testing and coverage reporting. Teams use it for unit and integration tests in React, Node.js and TypeScript projects, usually alongside Testing Library for components. Look for engineers who test behavior rather than implementation details, use mocks sparingly, keep snapshots small and meaningful, and keep the suite fast in watch mode and CI. Ask how they test async code and timers, and how they would choose between Jest and Vitest for a new project.

Vetting

How we vet Jest engineers

Every Jest engineer passes a profile review of their CV and the test suites they have built, followed by a communication check, since good QA means writing clear bug reports and pushing back on risky releases. A senior engineer leads the technical interview, probing test design, choosing what to automate, framework structure, handling flaky tests and CI integration, with live coding against a real web app. Only the top 1.5% of applicants are accepted and published.

Typical engagements

Build an end-to-end regression suite from scratch for your most important user journeys
Stabilize a flaky test suite and wire it into CI so every pull request gets a trusted result
Migrate an aging test framework to a modern one without losing coverage
