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). Tech Stack

Language Swift 5.9+

UI SwiftUI + UIKit (hybrid)

Reactive Combine, async/await

Real-time URLSessionWebSocketTask / Starscream, Combine streams

Charting Charting library via WKWebView bridge

Testing XCTest, XCUITest (E2E), Instruments profiling

Responsibilities

1. Cross-Platform Mobile Development

• Build, maintain, and scale production-grade React Native applications for both Android and iOS platforms from a single codebase.
• Translate product requirements and UX designs into clean, modular, and reusable React Native components.
• Develop rich, intuitive user interfaces for AI/ML dashboards, real-time analytics, and consumer-facing applications.
• Own features end-to-end — from technical design through to deployment on Play Store and App Store.

2. Native Integration & Bridging

• Write custom native modules and bridges in Kotlin/Java (Android) or Swift/Objective-C (iOS) to extend React Native's capabilities where required.
• Integrate third-party SDKs, device hardware APIs, and platform-specific features seamlessly into the React Native layer.
• Ensure consistent functionality and behaviour across a wide range of Android and iOS devices and OS versions.

3. Real-Time & Data-Driven UI

• Build real-time UI components that handle live data streams, WebSocket connections, and high-frequency data updates with minimal latency.
• Develop data-intensive views including charts, dashboards, and monitoring interfaces optimised for mobile performance.
• Ensure smooth, responsive user experiences under high-traffic and data-heavy conditions.

4. Performance & Optimization

• Profile, debug, and optimize application performance using tools such as Flipper, Hermes, React DevTools, and platform-native profilers.
• Minimize app bundle size, reduce render cycles, and improve startup time through best-in-class optimization techniques.
• Ensure accessibility compliance and cross-device UI consistency across varying screen sizes and resolutions.

5. Architecture & Code Quality

• Design and implement scalable mobile architectures supporting modularity, testability, and long-term maintainability.
• Implement robust state management using Redux, Zustand, MobX, or React Context depending on application complexity.
• Establish and uphold mobile coding standards, component libraries, and reusable design systems across the team.

6. Collaboration & Delivery

• Partner closely with backend, AI/ML, data engineering, and design teams to integrate APIs, data pipelines, and workflows.
• Actively participate in code reviews, sprint ceremonies, and technical design discussions.
• Support CI/CD pipelines using Fastlane, Bitrise, or equivalent tools for automated builds and releases.
• Contribute to OTA update strategies using CodePush or equivalent.

Required Skills & Qualifications

• Strong hands-on experience building and shipping production React Native applications on both Android and iOS.
• Proficiency in JavaScript and TypeScript — TypeScript strongly preferred.
• Experience with state management libraries — Redux, Zustand, MobX, or Context API.
• Solid understanding of React Native architecture — Bridge, JSI, Hermes engine, and the New Architecture (Fabric/TurboModules) is a plus.
• Experience writing native modules or bridges in either Kotlin/Java or Swift/Objective-C.
• Hands-on experience with REST APIs, GraphQL, and WebSockets in a mobile context.
• Strong understanding of mobile UI/UX principles, responsive design, and platform-specific design guidelines (Material Design & HIG).
• Experience with CI/CD pipelines and app store deployment processes.

Preferred Skills

• Experience building data-intensive or dashboard-heavy mobile applications.
• Familiarity with data visualization libraries such as Victory Native, Recharts, or D3.js for mobile.
• Exposure to AR/VR or graphics-intensive mobile experiences (ARKit, ARCore, React Native Vision Camera).
• Experience with OTA updates via CodePush or similar tools.
• Familiarity with monorepo setups (Nx, Turborepo) for managing shared mobile codebases.
• Understanding of accessibility standards (WCAG) and inclusive design on mobile.
• Exposure to AI/ML integration on mobile — on-device inference, TensorFlow Lite, or CoreML.
