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.
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—and you apply them pragmatically.
- You have working knowledge of AI/ML or LLM-powered features and you can translate that into practical quality checks.
- You communicate clearly and think pragmatically—you balance quality, speed, and risk to help the team ship responsibly.
- Nice to Have
- You’ve tested AI/LLM features before (prompt variations, guardrails, unexpected outputs, evaluation approaches).
- You bring exposure to performance testing and/or security testing basics.
