About Us

Athlitix is a US-based startup building cutting-edge sports technology that will change how athletes train and get recruited. Our immediate focus is on iOS using Flutter, but our roadmap includes future Android expansion, deep sensor integration, and advanced AR features. Join us to make a real impact with high ownership and creative freedom.

Role Summary

We're looking for a Senior Flutter Developer with exceptional expertise in building visually stunning, performance-critical mobile applications. You'll own the frontend development of our sports analytics platform, working extensively with camera integration, video processing, real-time data visualizations, and complex UI overlays.

Collaborate closely with cross-functional teams (product, design, backend) in a remote, distributed startup environment.
Ensure best practices for mobile UX, app performance, and code quality.
Take high ownership—proactively drive features, debug / troubleshoot, and deliver value at startup pace.
Attend regular standups and meetings with founding team
