Senior Frontend Engineer (Mobile – React Native)

🇨🇦 Canada | Remote

💰 $140K–$145K CAD

I’m working with a fast-growing sports gaming startup building one of the most ambitious mobile products in the space right now.

They’re looking for React Native engineers to join a small mobile team and help build the apps powering their sportsbook, fantasy, arcade, and casino products across iOS and Android.

The team is still relatively small, so they need someone who really understands React Native and is comfortable owning features end-to-end.

What you’ll work on

• Building and shipping features in React Native + TypeScript
• Developing complex mobile UI (betting slips, game lobbies, player props)
• Working with real-time data streams (WebSockets) for live updates
• Creating gesture-driven interactions and animations
• Optimising performance across iOS and Android
• Helping evolve a shared design system with 100+ components

Tech

React Native • TypeScript • Reanimated • WebSockets

What they’re looking for

• 4+ years frontend experience
• 2+ years building production React Native apps
• Strong TypeScript skills
• Experience shipping polished mobile products
• Someone comfortable debugging across iOS + Android

Why this role is interesting

• Real-time products used by millions of players
• A lot of technical depth (animations, real-time data, performance)
• High ownership in a growing mobile team
• Fully remote across Canada

If you’re a React Native engineer who enjoys building polished, high-performance mobile apps, happy to share more.
