• Test software to ensure performance and reliability.

• Troubleshoot, debug, and update applications.

• Stay up to date with industry trends and ensure our apps remain innovative.

• Work in a continuous delivery environment.

• Collaborate with the product team to ensure intuitive and user-friendly solutions.

What we’re looking for:

• 5+ years of experience in mobile development (3+ years with Flutter & Dart)

• Understanding of OOP, SOLID, and DRY principles

• Experience working with REST API, JSON, HTTP, Web-Socket, Analytics SDK, Firebase

• Understanding of different state management approaches (Provider, BLoC, GetX)

• Understanding of version control systems (Git)

• Understanding of the app publication process for Google Play and App Store

Why it’s exciting to work with us:

• Work with cutting-edge technologies and contribute to building AI-powered tools

• Join a strong A-level team that motivates you to grow and achieve more

• Remote-first approach: work from anywhere, with the option to visit our offices in Warsaw and Kyiv

• Paid day offs and sick leaves — we care about your work-life balance

• Regular performance reviews to ensure your growth is transparent and rewarded
