Software Development Engineer – Mobile App Development

Tennis Channel is building the future of digital sports streaming. We are rebuilding our entire Direct-to-Consumer (DTC) platform, from mobile to connected TVs, to deliver world-class live and on-demand tennis experiences to millions of fans. As a Software Development Engineer (Mobile App Development), you will help design, build, and scale high-performance applications across iOS, iPadOS, and Android using React Native, Swift, and Kotlin, while partnering closely with teams building backend services, CMS platforms, and video streaming infrastructure.

In this role, you'll contribute to experiences that power content discovery, playback, personalization, and fan engagement across multiple devices. You'll work with technologies including React Native, native iOS and Android modules, AWS services such as API Gateway, Lambda, CloudFront, and S3, while integrating analytics SDKs, DRM systems, and server-side ad insertion (SSAI) solutions. Experience with modern React Native libraries such as Reanimated, React Navigation, Redux, and Hermes will help you quickly make an impact.

This is a rare opportunity to join a small, senior engineering team building a greenfield sports product from the ground up, where every line of code directly shapes the fan experience. Ideal candidates will bring a passion for building consumer-facing applications and have experience developing sports, entertainment, media, or streaming products at scale.

· Integrate advanced playback features (DRM, adaptive bitrate streaming, live DVR, ad markers).

· Ensure high app performance, stability, and quality through automated testing and monitoring.

· Contribute to architecture, component design, and developer tooling that support hybrid app scalability.

· Stay current with Apple, Android, and React Native ecosystem improvements.

Qualifications

· Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience).

· 5+ years of experience building and shipping iOS and/or Android applications.

· Strong proficiency in React Native, Swift, and/or Kotlin.

· Deep understanding of UIKit, SwiftUI, AVFoundation, Jetpack, and concurrency patterns on both platforms.
