• Support regular testing sessions for mobile game builds
• Check build versions, feature flags, test environments, and relevant configurations during testing
• Run smoke, exploratory, and acceptance tests across iOS and Android devices
• Help us improve our QA workflows and contribute ideas around useful automation processes where it makes sense

What we expect

• 3+ years of experience in manual QA testing, ideally with mobile F2P games
• A good understanding of how mobile games work, especially live features, events, tutorials, offers, shops, and player flows
• Hands-on experience testing games or apps on iOS and Android devices
• Confidence in working with test plans, test cases, bug reports, and QA documentation
• Experience with regression testing, smoke testing, exploratory testing, and feature testing
• A keen eye for detail and the ability to reproduce, isolate, and explain issues clearly
• A reliable, structured, and hands-on working style, with clear communication across different teams
• Experience with test automation processes is a plus

What we offer

• Flexible working hours and a hybrid work model
• Interesting and challenging tasks in a team-oriented company with a flat hierarchy and international atmosphere
• Work with passionate, knowledgeable, and experienced colleagues where your ideas and perspective matter
• Plenty of opportunities to connect through events, BBQs, culture dinners, seasonal parties, gaming sessions, sports activities, yoga classes, and more
• Work in our well-situated Berlin Mitte office, with its vibrant atmosphere, sunny rooftop terrace, free drinks, fresh fruit, and plenty of room for fun (Playstation, darts, table tennis, and much more)
• Company pension contributions, supplementary health insurance, and access to Super Duolingo
• A secure job in a company that has been profitable since 2003
