ANDROID DEVELOPER JOB DESCRIPTION

Android Developer means owning the code that lands in millions of pockets. This role carries direct accountability for the native application layer, from architecture decisions to the CI/CD pipeline that ships builds to the Google Play Store and, in some organizations, the Huawei AppGallery. Consumer-facing apps at scale impose constraints that backend work rarely does: Activity and Fragment lifecycles, memory pressure across hundreds of device configurations, and UI responsiveness standards measured in milliseconds. The developer in this seat answers to product, design, and QA simultaneously.

As the Android Developer, you translate product requirements into production-ready native Android features while owning code quality, automated test coverage, and performance across the full device matrix your users carry. You work within a cross-functional squad alongside backend engineers, UX designers, and QA specialists, reporting into an engineering lead or Head of Mobile.

Career Impact: Deep ownership of a consumer-facing Android codebase, from architecture to Play Store release, builds the kind of platform-specific expertise that commands senior and lead-level mobile roles in the market.

Business Impact: Every release you ship reaches the end users who judge the product on responsiveness and reliability, meaning your day-to-day decisions directly shape retention and store ratings.

Growth Opportunity: Regular exposure to CI/CD pipelines, architectural patterns such as MVVM and Clean Architecture, and cross-platform coordination with iOS teams expands your scope toward mobile tech lead or principal engineer tracks.

Company Value: Several employers in this space explicitly support open-source contributions, technical blogging, and conference participation as part of professional development expectations.

• Design and implement native Android features across phone and tablet form factors, meeting UI responsiveness and performance targets.
• Architect application structure using established patterns to ensure maintainability and testability of the codebase.
• Develop unit, integration, and UI tests to validate feature behaviour and guard against regressions.
• Review pull requests from peers with attention to design decisions, missing test coverage, and adherence to coding standards.
• Collaborate with UX designers, product managers, and backend engineers to translate requirements into technical specifications.
• Integrate backend APIs and third-party services, ensuring secure, efficient data exchange within the app.
• Manage releases to the Google Play Store, including build configuration, signing, and post-launch monitoring of app health metrics.
• Mentor junior engineers on design techniques, coding standards, and Agile development practices.

• Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent work experience.
• 3 or more years of native Android development experience, with at least one app published on the Google Play Store.
• Proficiency in Kotlin and Java, with a solid understanding of Android SDK fundamentals, including Activity and Fragment lifecycles, threading, and memory management.
• Working knowledge of common architectural patterns, such as MVVM or MVP, and object-oriented design principles.
• Demonstrated ability to write and maintain unit and UI tests as part of a regular development workflow.
• Experience integrating RESTful APIs and working with JSON data structures in a production application.
• Proficient with version control using Git within a collaborative, multi-developer repository.
• Familiarity with Agile or Scrum methodology and experience participating in sprint ceremonies.

• Experience configuring and maintaining CI/CD pipelines for automated build, test, and deployment of Android applications.
• Exposure to reactive programming patterns and asynchronous data handling within Android applications.
• Familiarity with domain-driven design, SOLID principles, and their application to modular Android architecture.
• Experience working with distributed or offshore development teams across multiple time zones.

• Crash-free rate per release, measuring stability of shipped builds across active device configurations.
• UI test pass rate, tracking automated coverage against the defined test suite on each build.
• Pull request review turnaround time in hours, reflecting responsiveness within the engineering team.
• Mean time to close a reported bug from triage to merged fix, indicating debugging and delivery speed.
• Play Store release frequency in deploys per sprint, measuring the team's ability to ship at a sustainable cadence.
• Typical tools: IDE and build tooling (commonly Android Studio, Gradle); version control and CI (commonly Git, Jenkins, or Bitrise).

• Base Salary Range: $105,000 to $145,000 per year
• Bonus: Annual performance bonus, typically 5% to 10% of base
• Equity: RSUs or stock options common at growth-stage companies
• Health Benefits: Medical, dental, and vision coverage for employee and dependants
• PTO: 15 to 20 days annually, plus public holidays
