Senior/Lead iOS Developer - SWIFT/Objective C

Role Overview :

We are looking for a seasoned Senior/Lead iOS Developer with 8 - 12 years of experience to spearhead the design, development, and maintenance of our high-performance native iOS applications. In this role, you will own the architectural decisions, drive engineering best practices, and mentor a talented team of developers. Because you will be working across both modern features and foundational code, a deep, dual-mastery of both Swift and legacy Objective-C codebase integration is absolutely essential.

Key Responsibilities :

1. Architecture & Design :

- Lead the architectural evolution of our iOS apps, ensuring they are scalable, maintainable, and built for high performance.

2. Feature Development :

- Write clean, robust, and testable code in Swift and Objective-C to implement complex UI components and core business logic.

3. Code Quality & Mentorship :

- Conduct rigorous code reviews, establish engineering standards, and mentor mid-level and junior engineers to foster a culture of technical excellence.

4. Performance Optimization :

- Diagnose and resolve complex performance bottlenecks, memory leaks, and concurrency issues using Xcode instruments.

5. Collaboration :

- Work closely with Product Managers, UX/UI designers, and backend engineering teams to define, scope, and ship new features.

6. CI/CD & Automation :

- Optimize the build, test, and deployment pipelines to ensure seamless delivery to the TestFlight and the App Store.

Technical Experience & Skills :

1. Mandatory Skills :

- iOS Ecosystem : 8+ years of hands-on experience building native iOS applications with a strong portfolio of apps published in the App Store.

- Languages : Expert-level proficiency in both Swift and Objective-C, including handling interoperability between the two in a single large codebase.

- IDE & Tools : Mastery of Xcode, including advanced debugging, profiling tools (Instruments), and memory management (ARC).

- Architecture Patterns : Strong command over architectural patterns such as MVVM, VIPER, or Clean Architecture.

- Core Frameworks : Deep understanding of UIKit, Core Data, Grand Central Dispatch (GCD), and Core Animation.

2. Preferred / Good-to-Have Skills :

- Experience transitioning legacy Objective-C codebases into modern Swift.

- Familiarity with SwiftUI and modern asynchronous programming (async/await or Combine).

- Experience with dependency managers like Swift Package Manager (SPM), CocoaPods, or Carthage.

- Solid understanding of automated testing tools (XCTest) and CI/CD tools (Fastlane, Jenkins, GitHub Actions, or Bitrise).

- Knowledge of standard web technologies and protocols (RESTful APIs, JSON, URLSession).

Qualifications :

- Bachelors or Masters degree in Computer Science, Information Technology, or a related field (or equivalent practical experience).

- Excellent problem-solving, analytical, and communication skills.

- Proven track record of technical leadership or mentoring small engineering teams in an agile environment.
