iOS Software Engineer (Azar)

Responsibilities

• Job Introduction

[Feature]

• Continuously add new features to Azar, collaborating with various roles such as design, server, and QA to discuss and implement the optimal solution for achieving goals. Each feature is directly implemented by the developer, who takes responsibility for it, and at the same time, actively shares the context and code of the feature with team members, aiming for a Collective Code Ownership culture where the entire team manages it together, not just a specific individual.

[Code review]

• To reduce easily missed bugs and improve code quality, all changes are code-reviewed based on Pull Requests. Formats or rules that can be mechanically checked are automated using tools like SwiftLint, SwiftFormat, and SonarQube. In reviews, the focus is on the appropriateness of the design, stability, readability, and test coverage to collectively create better code.

[Testing]

• Unit Tests are written for core logic to maintain stability even with repeated code changes. Test code plays a significant role in discovering and preventing potential bugs before the code review or QA stage. Developers must write test cases for the core functions or main processing logic of the code they write, which is one of the team's quality standards.

[Troubleshooting]

• To ensure that the deployed app maintains performance and stability that meets user expectations, various runtime data such as crash information, performance metrics, and network connection status are monitored in real-time. In particular, stability issues are periodically reviewed and improved to increase the crash-free session rate and provide a predictable user experience. Additionally, major performance bottlenecks or connection failures are detected early, quickly analyzed, and resolved to continuously optimize the overall quality of the app.

[Architectural improvement]

• To enhance long-term productivity and maintainability, the introduction of new technology stacks or architectural paradigms is actively considered. The complexity of the code is reduced through a consistent and predictable structure, and modern development methods such as Swift Concurrency and multi-modularization are gradually applied to improve the quality of the entire codebase. Furthermore, design improvements are made to reduce side effects and transition to a structure that facilitates feature expansion and testing.

Requirements

• Experience in iOS development using UIKit, Foundation, etc., based on Swift.
• Understanding of basic computer science concepts such as data structures, algorithms, memory models, and operating systems.
• Ability to give and receive constructive feedback and communicate smoothly during code review and collaboration.
• Ability to actively recognize problems and proactively solve them.

Preferred Qualifications

• Understanding and experience with Combine and Swift Concurrency.
• Experience with testing using XCTest or Swift Testing frameworks.
• Understanding of network protocols such as WebRTC, TCP/UDP, TLS.
• Experience in UI/UX performance optimization.
• Experience in designing and operating multi-module based projects.
• Understanding of real-time data streaming processing.
