Mobile Engineer (iOS & Android)

About the role

The Mobile Engineer builds and operates native iOS and Android experiences used by customers daily. Working with product, design, backend, and platform teams, you will turn requirements into reliable mobile workflows, making sound architectural decisions and improving development experience through testing and observability.

Key responsibilities

• Design and ship customer‑facing features for iOS using Swift and SwiftUI and for Android using Kotlin and Jetpack Compose.
• Build reliable integrations with REST or GraphQL services, handling authentication, caching, synchronization, error handling, and offline workflows.
• Define and evolve mobile architecture using patterns such as MVVM, unidirectional data flow, modularization, and dependency injection.
• Improve application quality through unit, integration, and UI testing (XCTest, XCUITest, Espresso) and profile performance (startup time, rendering, battery, memory, network).
• Own mobile releases via CI/CD pipelines, feature flags, crash monitoring, and staged rollouts using tools like Firebase, Sentry, Fastlane, or Bitrise.
• Collaborate in design and code reviews, document technical decisions, and mentor engineers on mobile best practices.

Required profile

• 3–8 years of professional software engineering experience, including at least 2 years delivering production mobile applications.
• Strong experience with either Swift/iOS SDKs or Kotlin/Android SDKs; experience across both platforms is a plus.
• Proficiency with modern mobile frameworks and patterns (SwiftUI, UIKit, Jetpack Compose, asynchronous programming, dependency injection).
• Hands‑on experience integrating REST or GraphQL APIs, authentication flows, push notifications, deep links, analytics, and third‑party SDKs.
• Understanding of mobile testing, CI/CD, crash reporting, performance profiling, and App Store/Google Play release processes.
• Bachelor’s degree in Computer Science, Software Engineering, or related field, or equivalent professional experience.
