Requirements: At least 5 years of professional Android development experience, or equivalent technical depth, with a proven track record of building and operating production mobile applications. Strong proficiency in Kotlin and demonstrated experience developing, releasing, and maintaining Android applications through the Google Play Store. Solid understanding of mobile engineering fundamentals, including application architecture, concurrency, networking, offline scenarios, performance optimization, and production reliability. Hands-on experience with multi-module Android architectures, dependency injection tools such as Hilt, Kotlin coroutines, StateFlow, unidirectional UI patterns, navigation, and WorkManager. Familiarity with modern Android development technologies, including Jetpack Compose and Material 3, alongside experience maintaining legacy implementations using XML layouts, Fragments, or ViewBinding. Experience with networking and persistence technologies such as Retrofit, OkHttp, and Room, as well as feature flags, experimentation, product analytics, crash reporting, and application observability. Practical experience with CI/CD pipelines, automated testing, code reviews, release management, and production monitoring. Familiarity with camera, media, scanning, or other device capabilities is an asset. A demonstrated AI-first mindset, including regular use of AI development tools such as code copilots, AI-assisted debuggers, and test generators. You must be able to critically evaluate AI outputs, validate their accuracy, and take full responsibility for the resulting code. Strong problem-solving, communication, and collaboration skills, combined with a product-oriented approach and the ability to connect technical decisions to customer needs and business outcomes. A bachelor's degree in Computer Science or a related discipline, or equivalent practical experience. Nice to have: Experience delivering Jetpack Compose applications at scale and modernizing legacy Android codebases, including migrations from XML and Fragments to Compose or from RxJava to Kotlin coroutines. Background in wholesale, digital marketplaces, auctions, or high-volume transactional mobile applications. Experience mentoring other engineers, reviewing iOS/Swift pull requests, or supporting cross-platform technical alignment. Familiarity with BrowserStack, device farms, automated UI testing, or hybrid application experiences built with WebViews. Benefits: Competitive salary: Annual compensation ranging from CAD $125,000 to $160,000, depending on experience, skills, qualifications, and other relevant factors.
