Senior QA Engineer (Berlin, hybrid)
Quality Assurance
Berlin, Germany
Posted on Oct 3, 2026
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.
