Mobile Application Developer, Android & iOS

About the Role

We are looking for a strong Native Mobile App Developer to build and maintain Android and iOS applications using Kotlin and Swift. The developer should be technically strong in application logic, architecture, debugging, API integration, and problem-solving, while also being comfortable using modern AI coding tools such as Antigravity, Codex, Claude Code, or similar agentic development tools to improve development speed and quality.

Key Responsibilities

• Develop native Android applications using Kotlin.
• Develop native iOS applications using Swift.
• Design strong application logic, workflows, and scalable architecture.
• Integrate REST APIs, authentication, push notifications, background tasks, and offline functionality.
• Handle file uploads, downloads, caching, synchronization, and secure local storage.
• Debug crashes, performance bottlenecks, and platform-specific issues.
• Manage Play Store and App Store releases.
• Work closely with backend, UI/UX, and product teams.
• Use AI coding agents effectively for development, refactoring, testing, debugging, and documentation.
• Break complex requirements into clear technical tasks that coding agents can execute.
• Review, validate, and improve AI-generated code rather than blindly accepting generated output.
• Guide coding agents with the right context, architecture, constraints, and implementation logic.

Requirements & Tech Stack

• Strong experience with Kotlin, Android SDK, Android Studio.
• Strong experience with Swift, iOS SDK, Xcode.
• MVVM / Clean Architecture.
• REST API integration and JSON.
• Coroutines, Flow, Room, WorkManager, Retrofit/OkHttp.
• Swift Concurrency, Core Data, URLSession, Keychain.
• Firebase Cloud Messaging and APNs.
• Background processing and offline synchronization.
• Mobile app security and secure token storage.
• Git and version control.
• Play Store and App Store deployment.
• Strong understanding of data structures, application logic, state management, and system design.

AI-Assisted Development Skills

Candidates should be comfortable working with tools such as:

• Codex
• Claude Code
• Antigravity
• Other AI coding agents / developer assistants

The candidate should be able to:

• Write clear prompts and technical instructions for coding agents.
• Provide agents with the right codebase context.
• Plan architecture before asking agents to implement features.
• Review AI-generated code for correctness, security, and performance.
• Detect incorrect assumptions or poor implementations made by agents.
• Use agents for debugging, refactoring, testing, and code review.
• Coordinate multiple agent-driven tasks without losing architectural consistency.

What We’re Looking For

We are looking for a developer who is strong in logic and engineering fundamentals, and can use AI agents as force multipliers while still taking full ownership of architecture, code quality, debugging, and final implementation.
