Mobile App Developer

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.

Why Legend?

• Engaging development opportunities at all levels.
• Tailored flexibility for your work-life balance.
• Annual discretionary bonus to reward your efforts.
• Paid annual leave PLUS a well-deserved break to recharge your batteries during the festive season! Our offices are closed between Christmas and New Year's, allowing you to enjoy downtime without dipping into your annual allowance.
• Exciting global Legend events, where we unite in person to ignite our shared passion and unveil the exciting strategies for the year ahead!
