Job description

We are looking for a passionate Software Development Engineer II - iOS to join our iOS engineering team and help build high-quality, consumer-facing mobile experiences. You will be responsible for designing, developing, testing, and shipping features for our iOS application. You will work closely with Product, Design, Backend, AI/ML, and other engineering teams to turn product ideas into polished, scalable, and reliable experiences. This role requires strong hands-on expertise in Swift and iOS development, good software engineering fundamentals, and the ability to independently own features from technical design through production.

Responsibilities:

• Design and develop high-quality iOS features using Swift, UIKit, and SwiftUI.
• Own features end-to-end from understanding requirements and technical design to implementation, testing, release, and production support.
• Build scalable, maintainable, and reusable components following modern iOS architecture and engineering practices.
• Work closely with Product and Design teams to translate product requirements and designs into intuitive user experiences.
• Integrate REST/gRPC APIs and build robust networking and asynchronous data flows.
• Work with modern Swift Concurrency (`async/await`, actors, Task) and/or Combine where appropriate.
• Write unit, integration, and UI tests to ensure reliability and regression protection.
• Debug complex production issues using Xcode debugging tools, Instruments, crash logs, and observability platforms.
• Identify and improve application performance, including startup time, memory usage, rendering performance, scrolling, and network efficiency.
• Participate actively in code reviews and contribute to improving engineering standards and practices.
• Work with modular codebases and contribute to reusable frameworks/packages using Swift Package Manager.
• Collaborate with backend, AI/ML, QA, DevOps, and other engineering teams to deliver features across the product.
• Stay current with Apple's latest technologies and evaluate new frameworks and APIs when they can improve the product.
• Contribute to technical design discussions and help make pragmatic architectural decisions.

The core requirements for the job include the following:

Core iOS Skills:

• 2+ years of professional software development experience, with significant hands-on iOS development experience.
• Strong proficiency in Swift and a solid understanding of Swift language fundamentals.
• Strong experience with UIKit and/or SwiftUI.
• Good understanding of iOS application architecture and design patterns such as MVVM, MVC, Coordinator, dependency injection, or similar approaches.
• Strong understanding of iOS fundamentals including: View lifecycle, Memory management / ARC, Closures, Protocols and generics, Error handling, App lifecycle, Threading and concurrency, Notifications and delegates
• Experience working with Swift Concurrency, async/await, actors, GCD, or Combine.
• Experience integrating RESTful APIs, JSON, authentication, caching, and asynchronous networking.
• Good understanding of local persistence technologies such as Core Data, UserDefaults, Keychain, or file storage.
• Experience writing unit tests and UI tests.
• Experience debugging and optimising production iOS applications.
• Strong understanding of Git, Xcode, Instruments, debugging, and profiling tools.
• Experience with App Store deployment, provisioning, certificates, TestFlight, and release processes.

Software Engineering Fundamentals:

• Strong problem-solving and analytical skills.
• Good understanding of Data Structures and Algorithms.
• Ability to write clean, readable, testable, and maintainable code.
• Understanding of SOLID principles and software design fundamentals.
• Ability to break down ambiguous problems into smaller, executable tasks.
• Ability to independently drive technical implementation of medium-size features.
• Good understanding of API contracts and client-server architecture.
• Ability to identify technical risks and communicate them early.

Good to Have:

• Experience building large-scale consumer applications.
• Experience with SwiftUI animations and advanced UI interactions.
• Experience with Swift Package Manager and modular iOS architecture.
• Experience with CI/CD for iOS.
• Familiarity with tools such as Firebase, Crashlytics, Sentry, Datadog, or similar observability platforms.
