About this career

Mobile developers ship apps to iOS or Android (or both, using cross-platform frameworks like React Native or Flutter). The role rewards attention to detail — every screen has to feel right on a small touchscreen, often over a flaky network. Good fit if you enjoy the visual side of programming and want fast feedback loops.
