Senior QA Engineer (Berlin, hybrid)

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. We'll onboard you on the rest
