On behalf of our Client from Japan, Mobilunity is looking for a Mobile QA Engineer.

Our Client provides a mobile application that delivers multilingual, easy-to-use informational guides to a global audience, with a strong focus on usability and performance in emerging markets. They are seeking a skilled Mobile QA Tester to help ensure a seamless user experience across diverse devices, especially low-spec smartphones common in Africa.

As a Mobile QA Tester, you will be responsible for testing their mobile app across multiple devices and OS versions to ensure high-quality performance, usability, and localization accuracy. Your work will directly impact product stability and user satisfaction, particularly in markets where device limitations and language adaptability are key success factors.

Responsibilities:

• Plan, execute, and document mobile testing across Android and iOS devices
• Test app features thoroughly for functionality, UI/UX, performance, and localization
• Validate the app on low-spec devices typical to African and emerging markets
• Identify, report, and help track bugs using a bug tracking system (e.g., Jira, Trello)
• Perform localization and language testing, especially for Japanese (JP) and English (EN) content

Required Skills & Experience:

• 3+ years of experience in mobile app testing (Android and/or iOS)
• Ability to read/understand Japanese (JP) – helps with localization verification
• Strong experience with manual testing; automation experience is a plus
• Comfortable testing on low-spec devices (memory/CPU constrained; older OS versions)
• Clear and professional communication in English

In return we offer:

• The friendliest community of like-minded IT people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program is designed to meet our team’s needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort, and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups

Come on board, and let’s grow together!
