Job description

Location:

Poland, Europe, Kazakhstan

Client:

A global mobility and urban services platform that offers ride-hailing, intercity travel, delivery, and task assistance, operating in over 700 cities across 47 countries, and is one of the most downloaded mobility apps in the world.

Project:

You’ll join a product delivery team responsible for developing and maintaining user-facing geo capabilities and real-time location tracking services. You’ll be working alongside backend, mobile, QA, and analytics colleagues.

Your work will include in-app geo features such as pickup/drop-off location selection, in-app navigation, route line visualization, Location Manager, and location snapping and accuracy optimizations, plus the integration layer supporting these experiences.

The broader technical context includes a microservices architecture with event-driven integrations and maps integration.

Project Duration

4 months+

Responsibilities And Tasks

• Design, develop, and maintain Android features end-to-end, from implementation through release.
• Build Geo-specific features: pickup/drop-off, ride/vehicle availability, route availability, and live vehicle tracking, integrating maps, geofencing, and location services.
• Develop UI in Jetpack Compose using established design systems, applying Clean Architecture, MVVM, and MVI/Redux principles.
• Integrate APIs, map SDKs, and third-party route/vehicle data.
• Identify and fix bugs and performance bottlenecks (memory, UI, battery, network); investigate production issues with root cause analysis to prevent regressions.
• Ensure code quality through testing, code reviews, and CI/CD pipelines; implement feature flags and A/B experiments for safe rollouts.
• Monitor app health via Crashlytics/Analytics and set up dashboards to track risks.
• Collaborate cross-functionally (Geo Data, Backend, QA) and participate in Agile ceremonies (planning, refinement, demos).

Our Expectations Of The Ideal Candidate

• 5+ years commercial Android development in Kotlin, with deep knowledge of Jetpack Compose, Coroutines/Flow, RxJava, and modern Android APIs (Retrofit/OkHttp, WorkManager, FCM, DataStore).
• Strong grasp of Clean Architecture, MVVM/MVI, offline storage, and concurrency.
• Hands-on experience with location-based features: maps, geofencing, real-time tracking, and routing/Geo SDK integration.
• Experience with performance optimization (memory, battery, UI, network) and RESTful API integration.
• Solid testing practices (unit/UI tests), CI/CD (GitHub Actions/GitLab CI), and code quality tooling (ktlint, Detekt).
• Familiarity with secure coding practices, Git workflows, and the full Google Play delivery lifecycle.
• Comfortable using AI-assisted dev tools (GitHub Copilot, Cursor, Claude) to speed up coding and review.

Nice To Have

• Experience with two or more long-term projects (roughly 6–12 months) involving location tracking specifically
• Experience integrating custom or proprietary mapping solutions, beyond standard SDKs

English:

Upper–Intermediate (B2+)

Soft Skills

• Proactive ownership and autonomous decision-making
• Cross-functional collaboration and stakeholder alignment
• Analytical troubleshooting and root-cause investigation
• Agility and commitment to tight delivery timelines
• Strong time management in a fast-paced delivery environment

We Offer

• Flexible working time.
• Social benefits and perks.
• Fully remote work.
• Professional and ambitious team.
• Transparent system of professional and career development.
• Learning opportunities, seminars and conferences and time for exploring new technologies.
• The opportunity to realize your potential outside the projects: we arrange meetups and conferences where our staff can perform, develop professional communities.

Join us and be part of a team that is changing the world through technology!
