[Hiring] Senior Mobile Engineer @Fanatics Betting & Gaming

Role Description

As a Senior Mobile Engineer, you'll contribute to a multi-platform app built on Kotlin Multiplatform, shipping features across Android, iOS, and additional targets from a shared codebase. You'll own complex work end-to-end, write code that sets the quality bar for the team, and help shape architecture decisions in a fast-moving product environment.

Our engineering strategy centers on KMP and Compose Multiplatform to deliver high-quality, consistent experiences across platforms — and the engineers who build it are expected to help keep that bar high.

Responsibilities

• Build and ship production-quality features across Android and shared KMP layers, taking ownership from design through deployment with minimal oversight.
• Implement features across core product domains — connecting Compose Multiplatform UI to shared business logic through clean MVI state management.
• Contribute to a layered, multi-module architecture, respecting module boundaries and shared platform contracts.
• Partner with shared platform teams to implement against declared interfaces, keeping app-specific logic cleanly separated from shared platform concerns.
• Collaborate with product, design, and QA to deliver reliable, pixel-accurate experiences across multiple platform targets.
• Write testable, well-structured Kotlin leveraging coroutines, flows, KSP-based codegen, and dependency injection patterns consistent with the team's standards.
• Conduct thorough code reviews, maintaining module boundary discipline and build system conventions.
• Participate in the on-call rotation, helping diagnose and resolve issues across platforms.
• Mentor junior engineers and contribute to a culture of continuous learning on the team.

Qualifications

• 5+ years of experience building scalable, consumer-facing Android applications with strong command of MVI architecture.
• Strong Kotlin proficiency — coroutines, flows, idioms, and best practices — with the ability to apply and share these effectively across the team.
• Experience with Kotlin Multiplatform — comfortable developing and scaling shared business logic in a multi-module KMP codebase.
• Hands-on experience with Compose or Compose Multiplatform, building design-system-compliant UI across platform targets.
• Proficiency in Gradle multi-module projects, including convention plugins and dependency management.
• Experience with CI/CD pipelines and automated mobile testing practices.
• Comfortable working across shared platform and library boundaries — implementing against declared interfaces without leaking platform-specific logic into shared modules.
• Clear communicator able to articulate technical decisions to peers, product, and design stakeholders.
• Agile/SCRUM experience with a track record of consistent, quality delivery.
• Team-first mentality with a drive to raise the bar continuously.

Bonus

• Compose Multiplatform experience across Android, iOS, desktop, and wasm targets.
• Experience with KSP-based codegen and Koin or similar DI in a KMP environment.
• Familiarity with feature flag systems and mobile observability tooling.
• Experience with backend services, distributed systems and event-driven architectures.
