Technical Lead - iOS

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+

Job Title: IOS Engineer (Remote)

Remote Working | Engineering Team | Full-time

The Impact you will create on the Job:

Developing SDKs on IOS with support for cross-platform technologies like ReactNative, Flutter along with hybrid development over platforms like Cordova.

Apply data structures and algorithms to optimize the code for a lower memory, battery, and processing footprint - all with the goal to build plug-and-play SDKs that don’t expect the app developers to write any supporting code in the app.

You will be liaising with the cross-functional teams to get an in-depth understanding of the functional requirements and propose scalable solutions.

As an individual contributor, you will tackle some of our broadest technical challenges that requires deep technical knowledge, hands-on software development and seamless collaboration with all functions.

You will envision and develop features that are highly reliable and fault tolerant to deliver a superior customer experience.

You will get an opportunity to work with some of the best talent while learning from various highly-functional teams in the company.

You will collaborate with your team and set an example by delivering high quality and innovative engineering solutions for complex use cases.

Plan and execute the roadmap with the engineering team to build and deliver next-generation systems.

What we look for?

Bachelor’s/Master’s degree in Computer Science/IT from premier institute.

2-4 years of industry experience in iOS development, with at least one live app on App Store.

Good knowledge of Objective-C, Swift 5, data structures and algorithms.

Fair understanding of Native Frameworks, specifically concurrency handling, data persistence (User Defaults, Keychain, Core Data), and background tasks.

Good understanding of iOS Frameworks related to UI and network.

Fair understanding of Apple’s concurrency handling, Core Data, and NS Operation classes.

Familiarity with developing UI with both XIB/Storyboard and code.

Good understanding of SDK integrations, debugging, and troubleshooting.

Interested in exploring mobile app development ecosystems like React Native, Cordova and Flutter.

Comfortable with tackling ambiguous problems and unblocking yourself.

Fair understanding of Push Notification ecosystem.
