About the Role
Betr is looking for a Frontend Engineer to join our mobile team! You'll build React Native and TypeScript applications powering our Sportsbook, Social Sweepstakes Sportsbook, Arcade, & Casino products across iOS, Android, and web.
This is a high-impact role to own features end-to-end, work with real-time WebSocket data feeds, build hardware-accelerated graphics and physics-based animations, and ship polished products to users across multiple US states with strict regulatory requirements.
What You'll Do
- Build and ship features for sportsbook, casino, and fantasy apps using React Native
- Implement complex UI: market layouts, betting slips, player props, lobby experiences
- Create physics-based animations and gesture-driven interactions (carousel pagers, radial controls, animated transitions)
- Work with canvas-based graphics for player cards, game visualizations, and dynamic effects
- Contribute to our theme-based design system with 100+ shared components
Real-Time & Integration
- Build and maintain WebSocket subscriptions for live odds, match updates, and user notifications
- Implement state synchronization between real-time streams and local stores
- Handle deep linking from push notifications, attribution links, and web referrals
- Integrate payment flows: in-app purchases, bank transfers, card entry with verification
Platform & Quality
- Debug and fix platform-specific issues across iOS, Android, and web
- Optimize performance: animation frame rates, render efficiency, memory management
- Write worklet functions for animation-thread execution
- Maintain E2E automation tests and contribute to CI/CD pipelines
What We're Looking For
- 4+ years of professional front-end development
- 2+ years building production React Native apps (iOS and Android)
- Strong TypeScript skills with modern patterns
- Experience with Reanimated: shared values, worklets, gesture handlers
- Track record shipping polished, production-quality mobile apps
- Experience debugging platform-specific issues
- Understanding of mobile performance optimization
Nice To Have
- Sports betting, gaming, or fintech experience
- Canvas-based graphics experience (React Skia or similar)
- Real-time data architecture (WebSocket management, GraphQL subscriptions)
- React Native Web / multi-platform experience
- Design system tooling (Storybook, visual regression testing)
- Payment integration experience (IAP, 3DS verification)
- E2E mobile testing experience
Why Join Us!
- High Impact: Own significant features that directly affect user experience and business metrics
- Technical Depth: Real-time systems, hardware-accelerated graphics, physics-based animation—not just standard mobile UI
- Product Variety: Work across sportsbook, casino, and fantasy verticals
- Growth: Rapidly expanding into new states and product lines
- Remote-First: Work from anywhere in Canada
