Senior QA Engineer (Berlin, hybrid)

Kittl Technologies GmbH; Berlin; On-site; EUR 70,000 - 110,000; Full time

Job summary

Kittl is seeking a Senior QA Engineer to join the Editor team in Berlin. You will own quality across features from requirement reviews to release sign-off, guiding what to test, how deep to go, and what to automate. You will ship faster with fewer bugs and report to the QA Manager.

You will develop testing strategies, perform early risk detection, and build automated Playwright + TypeScript E2E tests integrated into CI. Strong exploratory testing and proactive communication are essential.

Qualifications

• 5+ years of experience in software QA with hands-on ownership of E2E testing for a complex web product.
• Exploratory and automated testing: strong in both approaches; neither pure manual nor pure automation.
• Playwright and TypeScript: hands-on experience building and maintaining E2E suites, ideally CI integrated.
• 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: provide engineers precise, actionable feedback and seek context.

Responsibilities

• Own the test approach for the Editor team's features and releases, with risk-based coverage.
• Join requirement and design discussions to catch edge cases and quality gaps early.
• Write and maintain Playwright + TypeScript E2E tests and integrate into CI for reliability.
• Perform exploratory testing on complex editor behaviour where automation alone misses issues.
• Lead bug triage and release validation for major launches, ensuring readiness to ship.
• Improve testing frameworks, CI workflows and QA practices, leveraging AI to speed test design and debugging.

Job description

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

• Recruiter interview (30 min)

• Take-home assignment

• Technical interview (60 min)

• CTO interview (30 min)

• Bar Raiser interview (45 min)
