Quality Assurance Engineer (m/f/d)

Your career oportunity (from 15.09.2026) You combine strong, hands-on software testing skills with a practical understanding of AI-driven product features and modern AI-supported QA workflows? Also you like to ensure reliable releases across web and/or backend systems, while also contributing to quality strategies for AI-enabled functionality? Then this position might be the perfect fit for you! Your Mission• You own our test strategy end-to-end—and you continuously improve it across both manual and automated testing as we grow. • You design, execute, and maintain test cases that cover new features, regressions, and the “it’ll never happen” edge cases. • You build reliable automated tests (E2E and API) and you keep them healthy in CI/CD—stable, meaningful, and easy to maintain. • You partner closely with Product and Engineering to clarify requirements early, tighten acceptance criteria, and prevent defects before they ship. • You define quality signals and metrics that create real release confidence—not just a gut feeling. • You raise the bar for AI-feature quality where relevant, including: - You test robustness across varied inputs (ambiguous prompts, noisy data, unexpected user behavior). - You check safety, privacy, and unintended outputs in line with product requirements. Requirements Your Superpowers• Your Superpowers • You’ve worked in software testing / QA engineering in cross-functional teams and you know what great collaboration looks like. • You’re strong in test design, exploratory testing, and defect investigation—you enjoy finding root causes, not just symptoms. • You have solid hands-on experience with test automation (e.g., Playwright, Cypress, Selenium) and API testing (e.g., Postman, Bruno). • You’re comfortable with CI/CD and version control (e.g., Git and GitHub/GitLab pipelines) and you treat testing as part of delivery. • You understand modern software delivery practices like shift-left QA, code reviews, observability, and documentation—an
