Senior iOS Developer

About the Role

We are looking for a Senior iOS Engineer to build and own the trading experience on iOS in Swift — real-time

data via Combine, interactive charting, smooth animations, and the premium feel expected of a financial

application. What We’re Looking For

You have shipped native Swift apps that handle real-time data, complex reactive pipelines, and

performance-sensitive UI. You know UIKit and SwiftUI deeply and can bridge between them confidently. Ideally, you have worked on trading, fintech, or data-intensive iOS products. You take ownership of your domain, drive

technical decisions, and hold yourself and your team to a high quality bar. What You’ll Do

• Own the mobile trading experience on iOS — module architecture, navigation, performance, and

end-to-end quality. • Build and optimize real-time data rendering using Combine — WebSocket streams, subscription

management, and efficient SwiftUI/UIKit binding. • Integrate complex WKWebView-based components with JavaScript–Swift message passing. • Collaborate with product and design to deliver polished, trust-building interfaces for a financial product. • Define iOS engineering standards — architecture patterns, testing strategy, accessibility, and

performance benchmarks. • Drive code reviews, mentor team members, and champion best practices across the iOS team. • Participate in stabilization and release cycles — Instruments profiling, device matrix testing, and

regression analysis. Must-Have

• 4+ years native iOS development with Swift in production apps on the App Store. • Strong Combine experience for reactive programming, data streams, and async coordination. • Experience with both SwiftUI and UIKit — ability to compose views and bridge between the two. • Experience with real-time data rendering and WebSocket integration on iOS. • Experience integrating WKWebView with JavaScript bridge (WKScriptMessageHandler). • Understanding of iOS architecture patterns — MVVM, Coordinator, Clean Architecture. • Experience with push notifications (APNs), deep linking, and Universal Links.

Nice-to-Have

• Prior experience building trading, brokerage, or fintech iOS apps. • Experience with charting library integration on iOS. • Experience building custom UI components — animated charts, calendar views, card-based layouts. • Knowledge of server-driven UI (SDUI) patterns for dynamic rendering. • Familiarity with accessibility best practices (VoiceOver, Dynamic Type).
