Fanatics is building a leading global digital sports platform. We ignite the passions of global sports fans and maximize the presence and reach for our hundreds of sports partners globally by offering products and services across Fanatics Commerce, Fanatics Collectibles, and Fanatics Betting & Gaming, allowing sports fans to Buy, Collect, and Bet. Through the Fanatics platform, sports fans can buy licensed fan gear, jerseys, lifestyle and streetwear products, headwear, and hardgoods; collect physical and digital trading cards, sports memorabilia, and other digital assets; and bet as the company builds its Sportsbook and iGaming platform. Fanatics has an established database of over 100 million global sports fans; a global partner network with approximately 900 sports properties, including major national and international professional sports leagues, players associations, teams, colleges, college conferences and retail partners, 2,500 athletes and celebrities, and 200 exclusive athletes; and over 2,000 retail locations, including its Lids retail stores. Our more than 22,000 employees are committed to relentlessly enhancing the fan experience and delighting sports fans globally.

About the Team

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, we're rebuilding how collectors discover, buy, sell, and experience their hobby — live, in real time, at scale.

Our flagship mobile product, Fanatics Live, is where that experience comes to life: live card breaks, real-time auctions, high-traffic chat, marketplace transactions, and deep collection management tools. The stakes are high and the traffic is real — we build for peak-load moments where latency is visible and reliability is nonnegotiable.

Role Summary

You’ll join the Instant Rips iOS team — the group responsible for the live-break commerce experience on Fanatics Live. We build the surfaces millions of collectors use in real time: bidding in live auctions, joining breaks, navigating a high-velocity chat stream, and transacting in the marketplace.

The iOS stack is modern by design. We're SwiftUI-first, run The Composable Architecture TCA) across the app, use Swift Concurrency throughout, talk to our backend via Apollo GraphQL, and maintain a clean modular SPM codebase generated with Tuist. There's no legacy UIKit app hiding under the surface — you’ll be working in a codebase you can be proud of.

AI tooling is part of how we work. We expect engineers to use it on the job, give it good context, and verify the output — not just accept it.
