Senior React Native Engineer

Job description

**Join Our Team as a Senior React Native Engineer at Beyond Sports** Are you excited about mobile architecture, high-scale digital platforms, and building the applications behind the future of sports entertainment? At Beyond Sports, we don’t just visualize sports, we reinvent how fans experience them. Together with partners like NFL, NHL, FIFA, and Disney, we push the boundaries of real-time sports data, 3D graphics, and AI-driven storytelling across global mobile platforms. If you’re passionate about driving technical quality, defining mobile architecture, and staying hands-on while delivering our next generation of cross-platform mobile applications, this could be your next move. **What Your Day Will Look Like** As a Senior React Native Engineer, you’ll sit at the center of mobile execution, system architecture, and technical quality. Your role combines high-impact code contribution with technical guidance. You’ll champion engineering best practices while contributing directly to architecture, complex technical challenges, and critical delivery moments. You’ll work closely with Product Management, UX/UI designers, and backend teams to shape and deliver outstanding mobile experiences for our global fan base. One day you might be diagnosing complex performance bottlenecks or streamlining deployment pipelines across iOS and Android ecosystems. The next, you could be designing native module integrations, refining state management strategies, or stepping into the codebase to unblock delivery. You’ll work with technologies like React Native core, JavaScript/TypeScript (ES6+), state management tools (e.g., Redux Toolkit, Zustand, React Query), and automated testing frameworks—always with a focus on scalability, reliability, and maintainability. Because driving quality starts with technical credibility, you’ll stay hands-on at your core. A significant part of your time will involve active engineering: solving complex mobile issues, improving app architecture, and supporting delivery where it matters most. Alongside this, you’ll help elevate peers, set code quality standards, and shape mobile development processes across the team. **What We Value** At Beyond Sports, we move fast, collaborate closely, and build things that haven’t existed before.
