The Role As a key contributor to our cross-platform strategy, you will architect and refine shared business logic using Kotlin Multiplatform (KMP). Your primary focus will be on engineering high-performance networking and data layers that serve both Android and iOS ecosystems. You won't just write code—you will take full ownership of the shared codebase, ensuring it remains scalable, maintainable, and robust in production. Operating at the heart of our mobile-to-backend infrastructure, you will drive technical excellence and help shape the future of our multiplatform development standards.
