We are creating software information systems providing management and reporting capabilities for customer equipment in the field. Currently, we are extending our team to be able to start new generation projects and looking for a passionate and motivated Middle Android Developer with 3+ years of relevant experience. The right candidate must be a team player with strong communication skills, and be comfortable working in a fast-paced environment.

Requirements

• 3 + years of experience in developing Android Apps
• Strong experience in estimation and planning
• Knowledge and experience in software design – analysis, concepts, design patterns, methods, documentation, and presentation
• English level (both Spoken and Written)  Upper-Intermediate or better
• Knowledge of Android APIs and SDK
• Understanding and experience in CI/CD concept and implementation

Job responsibilities

• Develop and update Android application
• Responsible for the implementation of new features: implementation, code review, supporting QA team during testing phase
• Work with the product owner for requirements capture and clarification
• Estimate and plan execution with the team
• Deliver high quality and well-verified products

Role Overview

We are building a unified mobile platform powered by Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP). Our Android version is production-ready, and we are now looking for a Senior Engineer to take ownership of the iOS implementation and launch.

This is not a traditional native iOS role. You will spend the majority of your time within the shared KMP/CMP ecosystem, ensuring that the shared codebase translates into a high-quality, performant iOS application. You will be the team’s bridge between shared Kotlin logic and the Apple ecosystem, responsible for everything from native platform integrations to Final App Store delivery.

Responsibilities

• KMP/CMP Development: Lead the implementation of features within the shared Kotlin codebase, focusing on iOS-specific UI/UX parity using Compose Multiplatform.
• iOS Integration: Build and maintain native bridges (Kotlin-Native/Swift) for platform-specific APIs, background processing, and hardware integrations.
• Performance & Quality: Optimize the shared UI to ensure it meets iOS-native performance standards, handling memory management and smooth animations on Apple devices.
• Release Management: Own the end-to-end iOS deployment pipeline, including Xcode workspace configuration, CocoaPods/Swift Package Manager integration, signing, and App Store Connect submissions.
• Architecture & Mentorship: Collaborate with the Lead Android Engineer to refine the shared architecture, ensuring it remains scalable and "iOS-friendly."

Requirements

• Strong Kotlin/KMP Foundation: Professional experience with Kotlin Multiplatform (KMP). You should be comfortable navigating shared logic and understanding how Kotlin compiles to Native/Objective-C frameworks.
• iOS Deployment Expertise: Proven track record of releasing and maintaining iOS apps. You must "speak" Xcode, understand provisioning profiles, and be comfortable navigating the App Store Connect lifecycle.
• UI/UX Sensibility: Experience with Compose Multiplatform or a strong desire to master it, paired with a deep understanding of Apple’s Human Interface Guidelines.
• Swift Proficiency: Ability to write clean, performant Swift code when native overrides or bridges are required.
• Mobile Architecture: Experience with modern architectural patterns (MVI/MVVM) and dependency injection in a multiplatform context.

• Native system APIs (push notifications, permissions, deep linking, StoreKit, etc.)
• App Store release process: signing, provisioning, TestFlight, CI/CD automation
• Ensuring Compose UI on iOS meets native-level standards (UX, accessibility, stability)
