Android Engineer

🏢 Summary: Senior Android Engineer role focused on building and scaling a high-performance fintech mobile application, contributing to architecture, code quality, and end-to-end feature delivery. The position involves developing modern Android solutions and collaborating cross-functionally to deliver secure, user-centric financial products. The engineer will help evolve the Android app using best practices and modern frameworks. 🗂️ Requirements: 5+ years of experience building Android applications, Strong knowledge of Kotlin and Android ecosystem, Experience with Jetpack, Coroutines, and Compose, Understanding of MVVM, MVI, and Clean Architecture, Experience with Android testing frameworks, Ability to design and scale Android app architecture, Experience collaborating with cross-functional teams, Experience in fast-paced environments, Experience in fintech or consumer tech startups 📃 Skills: Kotlin, Android, Jetpack, Coroutines, Compose, MVVM, MVI, CleanArchitecture, Testing, Git 🏢 Description: Our Mission We are building the financial system for the next century. One where control sits in the hands of customers — not banks. Where money moves on rails that are faster, smarter, and radically more efficient. Where wealth management tools help you grow your savings for decades — and build generational wealth. Where fewer intermediaries mean more value stays where it belongs: in our customers’ pockets. We operate with long-term ambition and absolute conviction. We are not here to iterate on the past — we are here to redesign it. This is a defining moment to join us. We are building what we believe will become one of the most important financial institutions in the world.
