This role is intentionally not defined by one framework or specialty. That said, you will likely operate in an environment that includes Kotlin-based native Android development, a large-scale multi-module Gradle codebase, Jetpack Compose and modern Android architecture, REST APIs, native payment SDK integrations, hybrid native↔web flows, experimentation and product analytics tooling, and mobile CI/CD pipelines. Depending on the project, you may also work with AI APIs, LLM-based workflows, retrieval patterns, and automation tooling.
