About Us At Madhaus, we're giving fans a stake in the unscripted. We build and operates sportsbook and casino brands, each crafted with its own personality, style, and edge to suit different types of sports fans. Our newest product, Bracco, is a sports and casino sweepstakes platform built for the everyday bettor. We're very early in its development, moving quickly, and working toward an ambitious product vision.

We're a small team of sports fans and builders with a lot of ground to cover. People here are trusted with real ownership, expected to move with urgency, and given the room to shape the product as it grows.

The Role This is a high-scope role focused on the future of Bracco's mobile experience. Today, our mobile apps use a WebView-heavy architecture. We’re moving toward fully React Native experiences that feel fast, fluid, and purpose-built for iOS and Android, and you’ll help lead that transition. That means building key flows, improving performance, tightening the user experience, and making thoughtful decisions about where native modules, gestures, animations, and platform-specific behavior can make the product better.

Mobile is central to our roadmap. A major focus over the next several months is improving activation and retention: helping users understand the product, find value quickly, and keep coming back. You'll work closely with product, design, backend, and frontend to shape and ship that work. We're looking for someone with strong ownership and initiative who wants to help build the best product in the space.

The role is a full-time, hybrid role based in Toronto, ON.
