What you will do
- Swift expert with deep SDK experience: You bring 8+ years of mobile development experience with a strong focus on modern Swift.

You know how to design clean, backward-compatible public APIs and package robust binaries (XCFrameworks) that thousands of external publishers can integrate with zero friction.
- High-performance rendering & creative UI/UX: You will build and optimize the visual components of adjoe Ads—innovative ad formats, dynamic video players, and rich web views seen by millions of users daily. Leveraging UIKit, AVFoundation, and WKWebView, you know how to build fluid, native-feeling experiences, introduce A/B testable UI features, and diagnose frame drops or memory leaks using Xcode Instruments.
