About the Role

We are looking for an App Developer to join a small, highly collaborative mobile squad responsible for optimizing and evolving our sports app. You'll primarily focus on creating engaging community experiences that keep users coming back, from social feeds and bet sharing to chat functionality and future interactive features. Beyond shipping new experiences, you'll help improve performance, optimize the app, and contribute to the technical direction of our React Native platform. This is an opportunity to have a significant impact on a product that's central to our future growth, helping move users from web-first experiences to an app-first ecosystem. You'll work closely with Product, Design and Engineering teammates and play an important role in shaping both the product and how the team builds it.

Responsibilities

• Develop, maintain, and optimize our React Native application using Expo, delivering high-quality features that support performance, scalability, and an exceptional user experience.
• Design and deliver features such as social feeds, bet sharing, chat, and other interactive experiences that encourage users to engage with the app and keep coming back.
• Partner closely with Product, Design, and Engineering teams to transform ideas into intuitive, user-centric mobile experiences while contributing to technical discussions and architectural decisions.
• Monitor application health using Crashlytics, proactively troubleshoot issues, and continuously improve app performance, stability, and release quality.
• Help establish React Native best practices, support other engineers as mobile development expands, and contribute to the technical direction of the app across squads.

Requirements

• 5+ years of software development experience, including 3+ years building mobile apps with React Native.
• Strong expertise with React, Expo, EAS, and TypeScript.
• Deep knowledge of iOS development, Apple Human Interface Guidelines, and app distribution via TestFlight.
• Proven experience with animations, performance optimization, and responsive mobile design.
• Experience integrating third-party identity providers (e.g., Google, Apple) and handling secure authentication flows.
• Proficiency with testing frameworks (Jest, Detox, Testing Library) and CI/CD workflows in agile environments.
• Familiarity with Git, backend API integration, and client-side data management strategies.
• Experience with Swift, Android development, Google Play distribution, or high-traffic consumer apps.
• Understanding of geolocation, deep linking, and offline data strategies.
• Background in sports, media, iGaming and high-traffic consumer apps.
