Senior Engineer, Android (Unified Experience)

Fanatics Collectibles is the home of sports cards trading cards and collectibles for over 100 million fans worldwide. As part of the global Fanatics platform were rebuilding how collectors discover buy sell and experience their hobby live in real time at scale.

Collectors move between live breaks instant rips auctions the marketplace and their collection every day. Currently those are sometimes distinct experiences and separate apps. Our work is to bring these experiences together as a single product and build new ways for collectors to discover what theyre looking for.

The role

Youll join theUnified Experience / Discoveryteam a new group responsible for building seamless collector journeys & discovery across Fanatics Live Marketplace Instant Rips Collections Topps and future experiences.

As the first Android developer on a new team youll be responsible for underlying architecture as we bring existing separate services closer together. You will also help implement new user-facing features we will build on top of that unified structure. This is a high-impact role with significant ownership and the work will require collaboration with stakeholders across the organization including other engineering teams (which may be downstream consumers of your work) product leaders and other business roles.

The Android stack is modern by design: Kotlin and Jetpack Compose throughout Coroutines and Flow for concurrency and state a unidirectional architecture with a strict state contract GraphQL against our backend and a modular multi-module Gradle codebase with automated build and release pipelines.

AI tooling is part of how we work. We expect engineers to leverage it have a productive workflow understand the code produced and own the results.

• Design and ship shared Android foundations reusable modules Compose components and internal libraries that multiple collector-facing apps depend on and treat the engineers consuming them as first-class customers.
• Own unified identity session and entitlement flows across surfaces so a collector signs in once and moves between Live Instant Rips Marketplace and Collections without friction.
• Lead migrations and consolidations against live users: persistence and data model changes deprecating divergent implementations and phased rollouts that dont break anyone mid-flow.
• Own features end to end API contracts state and effect handling Compose UI testing and release.
• Build deep linking navigation and cross-surface handoffs that make separate products behave like one.
• Write genuine test coverage: unit tests with fake dependencies Flow and coroutine test patterns Compose UI tests where they earn their keep not coverage theater.
• Instrument what you ship and watch it in production: event tracking feature flags staged Play Store rollouts crash and ANR triage and monitoring you actually check after launch.
• Own Android performance where users feel it: startup time jank in scrolling and animation-heavy surfaces memory under sustained real-time load.
• Review pull requests with judgment: surface real defects prioritize what matters coach on what to let go.
• Contribute to architectural decisions: modularization strategy state management effect handling failure handling.
• Mentor engineers earlier in their career and raise the quality bar across the team.

• 5 yearsbuilding consumer-facing Android applications at scale.
• Kotlin coroutines structured concurrency Flow and a working understanding of where each belongs.
• Jetpack Compose state hoisting recomposition and stability performance-aware composition Compose Navigation.
• Unidirectional state management at scale MVI or a comparable strict testable architecture (Molecule Orbit Mavericks or a well-reasoned in-house pattern) that you can explain and defend.
• Multi-module Gradle architecture clean module boundaries convention plugins version catalogs build times youve actively fought for.
• Shared architecture across multiple apps youve built reusable modules SDKs or internal libraries consumed by more than one app or more than one team and you understand the API-stability and versioning discipline that requires.
• Dependency injection Hilt Dagger Koin or equivalent used deliberately rather than by habit.
• GraphQL on Android Apollo Kotlin schema-driven development codegen subscriptions.
• CI/CD Bitrise GitHub Actions Fastlane or equivalent automated build/test/release pipelines feeding the Play Console.
• Testing discipline JUnit Turbine Robolectric Compose testing and instrumentation tests with real assertions.
• Static analysis ktlint detekt or equivalent quality gates.
• Hands-on with AI-assisted development tooling Claude Code Cursor Copilot or similar with a track record of using it for real work not demos.
• Structured commit/PR disciplinetied to a project tracker (Linear Jira or equivalent).
• Comfortable working across team boundaries this role depends on influence with engineers you dont manage.

• Experience with livestreaming real-time auctions or high-throughput WebSocket/subscription workloads.
• Baseline Profiles Macrobenchmark or other systematic Android performance work.
• Exposure to marketplace or e-commerce Android applications.
• Payments billing or Play Billing experience.
• Developer tooling or internal platform work that measurably saved other engineers time.
• Passion for sports cards collectibles or live commerce.
