Your role at Kittl 🥁 Kittl's editor is a browser-based design tool, and every release has to hold up across canvas, typography, effects, export and AI workflows for millions of users. As a Senior QA Engineer, you'll be embedded in our Editor team and take part in the full feature cycle, from requirement reviews to release sign-off. You'll own quality for that team: deciding what to test, how deep to go and what to automate, so we ship faster without shipping bugs. This role reports to the QA Manager. 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.
