About the Role

We are looking for a strong iOS Developer with 3–5 years of professional experience in building scalable, high-performance native applications. The ideal candidate has deep expertise in Swift, strong architectural understanding (MVVM, MVVM-C, VIPER, Clean Architecture), experience contributing to SDKs or modular systems, and a strong foundation in clean coding principles and core computer science fundamentals.

You will take ownership of core modules, ensure high engineering standards, and build reliable, maintainable, and performant mobile systems.

Roles & Responsibilities

• Design and build scalable native iOS applications using Swift, UIKit and/or SwiftUI.

• Architect modular features using MVVM / MVVM-C / VIPER and Clean Architecture principles.

• Contribute to reusable mobile modules or SDK components with clear abstractions and API boundaries.

• Write clean, maintainable, and well-structured code following SOLID principles and best practices.

• Ensure high performance, responsiveness, and efficient memory management.

• Implement robust networking layers integrating RESTful APIs with proper error handling and security considerations.

• Identify bottlenecks, debug crashes and memory leaks, and optimize runtime performance using profiling tools.

• Maintain code quality through reviews, refactoring, and documentation.

• Support CI/CD workflows, version upgrades, and App Store releases.

Must-Have Skills

• 3–5 years of hands-on iOS development experience using Swift.

• Strong understanding of architectural patterns: MVVM, MVVM-C, VIPER, Clean Architecture.

• Experience building modular components or contributing to iOS SDKs.

• Solid understanding of OOP concepts, SOLID principles, and writing clean, extensible code.

• Strong problem-solving ability with good exposure to Data Structures and Algorithms.

• Solid understanding of concurrency (GCD, async/await), threading, and performance optimization.

• Strong knowledge of memory management (ARC), retain cycles, and runtime behavior.

• Experience writing unit tests (XCTest) and building testable systems using dependency injection.

• Proficiency with Git and modern dependency managers (SPM, CocoaPods, Carthage).

• Experience integrating RESTful APIs and working with backend systems.

• Hands-on experience with App Store submission and release processes.

Good to Have

• Experience with dependency injection frameworks (e.g., Swinject).

• CI/CD exposure (Fastlane, Jenkins, GitHub/GitLab pipelines).

• Experience profiling and debugging performance issues in production environments.

• Exposure to AI/ML integrations (CoreML, Vision, or third-party AI services).

We are looking for a React Native developer interested in building performant mobile apps on both the iOS and Android platforms. You will be responsible for architecting and building these applications, as well as coordinating with the teams responsible for other layers of the product infrastructure. Building a product is a highly collaborative effort, and as such, a strong team player with a commitment to perfection is required.

• Build pixel-perfect, buttery smooth UIs across both mobile platforms.
• Leverage native APIs for deep integrations with both platforms.
• Diagnose and fix bugs and performance bottlenecks for performance that feels native.
• Reach out to the open source community to encourage and help implement mission-critical software fixes—React Native moves fast and often breaks things.
• Maintain code and write automated tests to ensure the product is of the highest quality.
• Transition existing React web apps to React Native.

• Firm grasp of the JavaScript (and TypeScript or ClojureScript) language and its nuances, including ES6+ syntax
• Knowledge of (functional or object-oriented) programming
• Ability to write well-documented, clean Javascript code
• Rock solid at working with third-party dependencies and debugging dependency conflicts
• Familiarity with native build tools, like XCode, Gradle (Android Studio, IntelliJ)
• Understanding of REST APIs, the document request model, and offline storage
• Experience with automated testing suites, like (Jest or Mocha)

What does the core role include?

• Designing and developing high-volume, low-latency applications for mission-critical systems and delivering high-availability and performance
• Designing stateless components in React Native
• Contributing in all phases of the development lifecycle
• Working with the developers to create and maintain a robust framework to support the apps
• Working with the developers to build the interface with a focus on usability features
• 
  

What else can you expect in the role?

• Prepare and produce releases of software components
• Optimizing performance for the apps
• Problem-solving skills, analytical mind, and positive attitude
• Ability to think from end users perspective and focused on improving the overall product experience.
• Deliver across the entire app life cycle concept, design, build, deploy, test, release to app stores and support
• 
  

What can fetch you brownie points?

• Hands on experience with React Native is required
• Hands-on experience in React Native APIs, ReactJS, Javascript, ECMAScript (OOJS) and JSX.
• Strong understanding of JavaScript ecosystem
• Hands on experience on Android in creating Hybrid / Native applications
• Demonstrable UI/UX experience on a large-scale app.
• Thorough understanding of React Native development tools like IDEs (Nuclide, Atom, Sublime Text, or Visual
• Good knowledge of JS frameworks like ReactJS is a plus.
