Our mission is to redefine how fans engage with the moments and markets that matter most. We're looking for the right people to help us build the future of prediction markets. As Senior Engineering Manager for Client Multiplatform, you'll lead the engineering team powering the Fanatics Markets app — a fast-moving, high-growth product at the intersection of sports and financial markets. You'll manage mobile engineers, set the technical direction for our Kotlin Multiplatform strategy, and partner across the organization to ship high-quality, customer-facing features consistently across platforms. This role demands a balance of deep technical credibility, strong people leadership, and the ability to influence executives and cross-functional stakeholders alike. The ideal candidate is energized by both platform enablement work and end-user product delivery — this role requires comfort with both.

Requirements

10+ years of software engineering experience, including 2+ years managing mobile engineering teams
Proven track record building highly scalable, consumer-facing Android applications using MVI architecture with deep understanding of unidirectional data flow and state immutability at scale.
Expert-level Kotlin proficiency — coroutines, flows (including Flow vs. SharedFlow distinctions), custom scopes, and thread dispatchers — with the ability to mentor others in its effective use.
Strong experience with reactive programming patterns and asynchronous data processing, including real-time data via WebSockets, gRPC, and Ktor for networking.
Experience designing offline-first data sync layers (e.g., SQLDelight) with an understanding of schema migrations, eventual consistency, and how distributed/async backend state surfaces through MVI to the end user.
Proficiency with Gradle build systems at scale — multi-module projects, convention plugins, remote build caching, dependency substitution, and custom plugin authoring.
Experience designing CI/CD pipelines that validate KMP changes across both Android and iOS builds, including strategies to catch shared module breakages before they reach native builds.
Hands-on experience with Jetpack Compose — including recomposition optimization, stability annotations, and state hoisting — and familiarity with Compose Multiplatform trade-offs.
Deep Android platform expertise — best practices, trends, and end-user considerations — with awareness of iOS conventions sufficient to ensure KMP modules remain idiomatic for both platforms.
Demonstrated ability to lead multi-team programs and scale engineering organizations through high-growth phases, including building cross-team alignment and handling skepticism from platform peers.
Expertise in Agile/Scrum delivery, with a track record of driving process improvements and clear, effective communication across engineering, product, design, and executive audiences.

Nice To Haves

Production experience with Kotlin Multiplatform (KMP), including shipped features — not just exploration. Familiarity with expect/actual patterns, interface injection, iOS interop, and the organizational challenges of cross-platform adoption.

Responsibilities

Lead, coach, and develop staff and senior engineers, fostering a culture of accountability, innovation, and continuous improvement.
Own end-to-end technical execution of complex features — from architecture and design to deployment and iteration — including proactive consideration of edge cases, testing, and operational concerns.
Partner with the client platform team to define and evolve shared standards, best practices, and UI libraries across the organization — balancing your product team's priorities with contributions back to the shared platform.
Provide architectural oversight for Kotlin/Java services built with Spring Boot, ensuring engineering best practices are upheld and integration points and dependencies are anticipated early.
Set and track engineering goals around availability, performance, quality, and delivery cadence — holding teams accountable to outcomes.
Recruit, retain, and scale top engineering talent through thoughtful hiring, mentorship, and inclusive team culture.
Lead multi-team planning and design discussions, introducing innovative approaches to technical challenges and driving adoption of best practices across platform boundaries without relying on formal authority.
Advocate for engineering at the executive level, influencing technology strategy and investment in distributed systems and mobile infrastructure — translating complex multiplatform decisions into terms that resonate with product and executive audiences.
