Senior Mobile Software Engineer (Android)

We are looking for a Senior Android Engineer who is architecturally strong, quality-driven, and AI-native to join our Mobile Engineering team. The best candidate will be someone who thrives in a fast-paced, highly collaborative, and exceptionally dynamic setting and is excited to own Android architecture decisions, ship polished Kotlin applications, and set the standard for how AI accelerates engineering at Xsolla.
 
Deep expertise in modern Android is essential: Kotlin, Jetpack Compose, Coroutines and Flow, and the Jetpack library surface, along with a proven track record of shipping commercial applications to Google Play from concept to launch. The ability to design scalable architectures, implement robust testing strategies, profile and optimize startup time, jank, memory, and battery across a fragmented device landscape, and mentor other engineers while collaborating across cross-functional teams will be key to your success in this role.
 
We build AI-first. We expect you to work fluently with AI coding agents as a daily multiplier - scoping work for them, reviewing what they produce with a critical eye, and building the internal tooling, context, and evaluation habits that make the whole team faster.
 
If you’re passionate about building high-quality Android experiences that scale, and love shipping apps that power gaming, virtual currency, and digital commerce experiences, we would love to hear from you!

Responsibilities
Design, build, and maintain our native Android application in Kotlin and Jetpack Compose, used by players and developers worldwide. Deliver high-quality features on time throughout the development lifecycle, from technical design through release and post-launch iteration. Own the full Android release process: signing, App Bundles, Play Console tracks, staged rollouts, pre-launch reports, and crash and ANR triage. Implement best practices for Android development, including code review, automated testing strategies, and CI/CD with Gradle, Fastlane, or equivalent. Integrate mini-apps, payments, and virtual currency systems into the Xsolla App ecosystem. Collaborate with product and design teams to turn business goals into experiences that feel genuinely native. Work with cross-functional teams, including backend developers, QA engineers, and project managers, and communicate effectively across distributed, multi-timezone teams. Participate in technical discussions to align development work with business objectives.

Architecture & Design
Design and implement scalable application architecture for Android with a focus on maintainability, performance, and developer experience. Lead architectural decisions around modularization, dependency injection (Hilt/Dagger), navigation, and state management (MVVM, MVI, unidirectional data flow). Configure and optimize the Gradle build, convention plugins, version catalogs, build caching, and configuration cache, for fast, incremental builds. Build and maintain an internal Compose component library and design system implementation. Establish and enforce coding standards, design patterns, and best practices across the mobile development team. Create technical specifications and architecture documentation for complex features and systems. Partner with the iOS and React Native engineers to keep shared API contracts, design tokens, feature flags, and analytics schemas coherent across the app family, without flattening the platform into a lowest common denominator. Drive observability for mobile: structured logging, crash monitoring, performance tracing, and release health dashboards.

AI-First Engineering
Use AI coding agents and assistants as a core part of your daily workflow, and raise the bar for how the team prompts, reviews, and verifies AI-generated code. Build and maintain the context that makes agents effective in our codebase: project rules, tool integrations, reproducible dev environments, and automated checks that catch what review misses. Design evaluation and guardrails for AI features, including prompt regression testing, fallback behavior, and handling of model failure modes in production. Share what works: mentor engineers on AI-assisted development and help set practical, quality-preserving standards for the organization.

Qualifications & Skills
5+ years of professional Android development experience, with deep, hands-on expertise in Kotlin. Proven track record of shipping commercial Android applications, with apps you built currently live on Google Play. Strong command of modern Android frameworks and idioms: Jetpack Compose, Coroutines and Flow, Lifecycle, Room, WorkManager, and Navigation. Strong understanding of Android architecture patterns (MVVM, MVI, Clean Architecture), dependency injection, and state management. Experience with automated testing on Android: JUnit, Compose UI tests, Espresso, Robolectric, and with CI/CD for Android release pipelines. Solid grasp of performance, memory, and battery profiling using Android Studio Profiler, Macrobenchmark, and Baseline Profiles. Experience building for a fragmented device and OS-version landscape, including large-screen and foldable form factors. Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent experience). Proven, daily use of AI coding agents and AI-assisted development tools (e.g. Claude Code, Copilot, Cursor) to accelerate real production work - scoping tasks for agents, critically reviewing AI-generated code, and measurably increasing your own and your team’s velocity. Experience with third-party integrations, REST/GraphQL APIs, and mobile SDK consumption. Strong problem-solving abilities and a results-driven approach. Effective communication skills, both written and verbal.

Nice to Have
Experience with app widgets, deep linking, push notifications (FCM), or background work at scale. Experience bridging Kotlin modules into React Native, or with Kotlin Multiplatform. Familiarity with Google Play Billing and alternative billing / external offer programs. Familiarity with gaming ecosystems, virtual currency platforms, in-app purchases, or alternative payment and digital commerce flows. Experience with mobile security practices: secure storage, certificate pinning, obfuscation, and fraud prevention. Contributions to open source, technical writing, or conference talks in the mobile or AI engineering space.

Benefits:We are passionate about fostering a supportive environment for our team, so we prioritize the physical, mental, and emotional well-being of our employees and their families through a comprehensive Benefits Program. This includes medical, dental, and vision, PTO, and a personalized career roadmap for each employee. By investing in professional development through training and educational opportunities, we ensure that our team thrives both personally and professionally.
