• Strong expertise in SwiftUI.
• Experience designing highly themeable and adaptive SwiftUI components.

• A deep appreciation for clean API design, backward compatibility, and minimizing binary size.
• A strong commitment to quality, including writing Unit/Integration/Snapshot/UI tests and code reviews.
• Excellent verbal and written communication skills in English.
• A willingness to learn and continuously improve.
• A flexible and open-minded approach to new ideas.

Nice to Have

What You'll Be Doing

• Ensuring Flawless, High-Volume Device Orchestration: It’s not just about backend volume; on the client side, we must ensure our POS Mobile SDK handles rapid, consecutive transactions without memory leaks, UI freezes, or state corruption on the device.
• Delivering Consistent Performance Under Any Condition: Ensuring a fast, reliable payment experience regardless of the iOS device model. You will build resilient local UI states that gracefully handle unpredictable network drops, hardware timeouts from card readers, and edge-case payment declines.
• Building a Future-Proof Mobile Architecture: Designing modular, highly extensible UI and interaction layers within our SDK. Your architecture will allow us to seamlessly plug in new payment surfaces, support dual-screen setups, and adapt to evolving merchant needs without rewriting core layout logic.
