ANDROID ENGINEER JOB DESCRIPTION

An Android Engineer writes the native code that runs on users' phones. Every tap, scroll, and notification on a consumer-facing Android app passes through work this engineer owns, from Kotlin architecture decisions to Play Store release pipelines. Consumer SaaS products serving millions of active users demand more than working features; they demand stable crash rates, fast render times, and accessibility compliance that holds across hundreds of device variants. That breadth of ownership, spanning product velocity and platform reliability simultaneously, is what separates this role from back-end or platform peers.

As the Android Engineer, you will own the full native Android codebase for a consumer-facing product - designing, building, and shipping features that directly affect user retention metrics and Play Store ratings. You partner daily with product managers, UX designers, and back-end engineers, operating within a cross-functional agile team accountable for both feature throughput and app stability at scale.

Career Impact: Sustained ownership of a high-traffic consumer Android app, including Play Store publishing decisions and architecture calls, builds the kind of production credibility that opens senior and staff-level mobile roles.

Business Impact: The features you ship determine whether users return the next day - retention rates, crash-free session percentages, and store ratings all move in direct response to your code.

Growth Opportunity: Exposure to Kotlin Multiplatform, Jetpack Compose migrations, and CI/CD pipeline ownership gives you a technical portfolio that commands a premium in the mobile engineering market.

• Design and implement new consumer-facing features in Kotlin from requirements through Play Store release.
• Conduct code reviews across the mobile team to enforce architectural consistency and test coverage standards.
• Diagnose and resolve production defects by analyzing crash reports, performance traces, and user-reported issues.
• Collaborate with UX designers and product managers to translate wireframes into accessible, performant Android layouts.
• Mentor junior engineers through pair programming and design review sessions to raise overall team output quality.
• Develop and maintain automated unit and UI test suites to sustain release confidence across Android OS versions.
• Evaluate emerging Android platform capabilities and recommend adoption into the team's architecture patterns.
• Integrate REST and GraphQL back-end APIs into the mobile client with attention to threading, caching, and error handling.

• Bachelor's degree in Computer Science, Software Engineering, or equivalent work experience.
• 3 or more years of professional Android development experience, with demonstrated production app delivery on the Google Play Store.
• Proficiency in Kotlin, including coroutines, flows, and modern Android architecture components such as ViewModel and Jetpack libraries.
• Strong command of Android application architecture patterns, including MVVM, MVI, or Clean Architecture.
• Experience with RESTful API integration, multi-threaded programming, and mobile performance optimization techniques.
• Ability to write and maintain automated unit tests and UI tests with measurable coverage targets.
• Effective written and verbal communication skills in English, with experience contributing to cross-functional agile teams.

• Experience with Jetpack Compose for declarative UI development or active migration of legacy View-based codebases.
• Familiarity with GraphQL API consumption, CI/CD pipeline configuration, or cloud infrastructure relevant to mobile back-ends.
• Background in mobile SDK development or experience contributing to shared internal libraries consumed by multiple product teams.
• Prior mentorship or technical leadership experience within a mobile engineering team.

• Crash-free session rate, reflecting the stability of shipped releases across the active device fleet.
• Play Store rating and review sentiment, indicating user response to feature quality and bug frequency.
• Mean time to resolve production defects, measuring responsiveness to critical issues in the live app.
• Automated test coverage percentage, tracking how reliably new code is protected against regression.
• Feature delivery cycle time per sprint, reflecting estimation accuracy and execution consistency.
• Typical tools: version control and CI/CD (commonly Git, GitHub Actions, or Bitrise); issue tracking (commonly Jira); Android development (commonly Android Studio, Espresso).

• Base Salary Range: $120,000 to $175,000 per year, varying by seniority and market
• Bonus: Annual performance bonus of 5 to 15% of base salary
• Equity: RSUs or stock options, typically 4-year vest with 1-year cliff
• Health Benefits: Medical, dental, and vision coverage for employee and dependents
• PTO: 15 to 20 days per year plus public holidays; some employers offer unlimited PTO
• Common Perks: Home office stipend, learning and development budget, mobile device allowance
