Staff Engineer

Overview 

As a Staff Web Engineer (React) at Fanatics Betting & Gaming, you are a recognized technical leader. You operate both strategically and hands-on—architecting scalable frontend solutions, driving ambitious projects, and setting the standard for engineering excellence. Your decisions thoughtfully balance immediate business needs with long-term technical vision. Through your leadership, you foster a culture of innovation, craft, and collaboration that leaves a lasting impact on your team and the broader web and frontend community.

We own the iCasino experience across Fanatics platforms—including our Casino Desktop Web product, the Standalone Casino App, and the iCasino embedded within our Fanatics Sportsbook & Casino App. As Staff Web Engineer, you will lead the evolution of our desktop web experience using React, contribute to internal back office tools, and work closely with engineers across mobile and shared codebases powered by Kotlin Multiplatform (KMP). While prior KMP experience isn’t required, this role will involve engaging with shared business logic and platform-level architecture written in Kotlin—so a willingness to learn and collaborate across stacks is essential. Familiarity with Java is also valuable, as you may occasionally contribute to content services that support our product experiences.

Our ambition is to build the top online casinos in the U.S.—fun, dynamic, and entertainment-first. We embrace best-in-class technologies, modern development principles, and platform agility to ensure we deliver on our Customer Promise and continuously innovate in this exciting and fast-paced market.
