Job description

What you\'ll do

Testing strategy: Own the test approach for the Editor team\'s features and releases, choosing functional, integration, regression and performance coverage based on real risk

Early risk detection: Join requirement and design discussions to catch edge cases and quality gaps before code is written

Automation: Write and maintain Playwright + TypeScript E2E tests for critical editor and AI flows, and make the suite stable enough that engineers trust it

Exploratory testing: Go deep on complex editor behaviour where scripts alone won\'t find the problem

Release readiness: Lead bug triage and release validation, and make the call on what\'s ready to ship during major launches

Raise the bar: Improve our testing frameworks, CI workflows and QA practices across teams, using AI to speed up test design, debugging and gap analysis

What you\'ll need

5+ years of experience in software QA, including hands‑on ownership of E2E testing for a complex web product

Exploratory and automated testing: You\'re strong at both and know when each one earns its place. Purely manual or purely automation profiles won\'t fit

Playwright and TypeScript: Hands‑on experience building and maintaining E2E suites, ideally integrated into CI

API testing: Comfortable testing APIs with tools like Postman or similar

Ownership and attention to detail: You treat product quality as yours and notice what others miss

Proactive communication: You give engineers precise, actionable feedback and go looking for context and work without waiting to be asked

Nice to have: experience testing design, image or creative tools, and a feel for concepts like vector vs raster. We\'ll onboard you on the rest
