QA Tester (f/m/d)

We are looking for an experienced and independent QA Tester to join us on a team focused on developing one of our biggest games. You will be directly embedded into a cross-functional team and work alongside developers, game designers, artists, and product managers to ensure our players can enjoy a satisfying and high-quality experience playing our game

• Partner closely with developers, game designers, and producers to define quality standards for upcoming features, acting as a proactive quality consultant rather than a passive gatekeeper.
• Take full end-to-end ownership of a feature’s lifecycle, managing everything from the initial bug report through final sign-off and providing clear, actionable insights to support product decisions.
• Plan, create, and execute comprehensive test plans that cover not only happy paths, but also edge cases, technical dependencies, and potential player misuse scenarios.
• Evaluate bugs critically based on business priorities and player impact, determining which issues must be addressed before release and which can be deferred to the backlog.
• Actively support the game’s release pipeline and monitor post-release stability using tools such as Crashlytics to identify, reproduce, and report live issues.
• Continuously seek opportunities to optimize QA pipelines and workflows, helping refine processes and advocating for QA best practices across the IBT team.

• Strong collaboration skills with the ability to thrive in highly cross-functional environments, provide clear feedback, and proactively seek support when needed.
• Proven experience in software testing (ideally in mobile games) with the ability to work autonomously and identify root causes of defects and issues.
• Demonstrated ability to create structured, logical test plans based on feature requirements and user stories, rather than simply executing predefined test cases.
• A quality-driven mindset that goes beyond bug discovery, with a strong understanding of business priority and severity and the ability to clearly articulate player and project impact.
• Solid experience working in Scrum/Agile environments and with project management tools such as Jira; familiarity with XRAY or similar test management tools is a strong plus.
• A thorough understanding of testing methodologies (functional, non-functional, sanity, regression, and exploratory), along with the judgment to apply them effectively in the right contexts.

• Experience working with Unity.
• Previous work on mobile titles, with an understanding of mobile-specific challenges.
• Familiarity with third-party SDKs and experience reading and analyzing logs (e.g., Firebase, Crashlytics).
• A proactive approach to continuous learning and professional growth.
