Job description

Role & responsibilities

We are looking for a Mobile Engineer with strong Kotlin Multiplatform (KMP) expertise to build and scale cross-platform

applications targeting both iOS and Android from a shared codebase. You will work closely with product, design, and

backend teams to deliver performant, native-feeling mobile experiences.

Key Responsibilities

• Design, develop, and maintain mobile applications using Kotlin Multiplatform, sharing business logic across iOS
• and Android.
• Build platform-specific UI using Jetpack Compose (Android) and SwiftUI / Compose Multiplatform (iOS).
• Architect modular, testable code following clean architecture and MVVM/MVI patterns.
• Integrate REST/GraphQL APIs, local persistence (SQLDelight, Room), and native platform capabilities (camera,
• location, push, biometrics).
• Optimize performance, memory, and battery consumption across both platforms.
• Collaborate with backend engineers on API contracts and with designers on pixel‑perfect implementation.
• Write unit, integration, and UI tests; participate in code reviews and mentor junior engineers.
• Manage CI/CD pipelines, app store releases, and monitor crash/analytics dashboards.

Required Skills

• Strong hands‑on experience with Kotlin and Kotlin Multiplatform (KMP/KMM).
• Proven native Android development experience (Kotlin, Jetpack Compose, Coroutines, Flow).
• Working knowledge of iOS development (Swift, SwiftUI/UIKit) and the ability to bridge Kotlin shared code into
• iOS.
• Experience with Ktor, SQLDelight, Koin/Kodein, and coroutine‑based async patterns.
• Solid understanding of mobile architecture patterns, dependency injection, and reactive programming.
• Familiarity with Gradle build systems, XCFrameworks, and CocoaPods integration for KMP.
• Experience with Git, CI/CD (GitHub Actions, Bitrise, or Fastlane), and Play Store / App Store release workflows.

Nice to Have

• Experience with Compose Multiplatform for shared UI.
• Contributions to open‑source KMP libraries.
• Knowledge of native iOS frameworks (Combine, Core Data) for interop scenarios.
• Exposure to smart city, IoT, or community‑tech domains.
