We are the #1 doctor-recommended – and most clinically studied – behavioral weight health program in the world. For sixty years, WeightWatchers has helped millions build healthy habits and live happier, healthier lives.

As the science of weight health rapidly evolves, so does WeightWatchers. Today we are developing new clinical pathways for medication access, creating behavioral programs for chronic health conditions, integrating third-party services, and enhancing product personalization.

WeightWatchers has embraced technology, with our mobile app now the  primary tool for most members. While we continue to perfect our digital product, we are also designing new in-person experiences. With these diverse member touchpoints, our potential for impact has never been greater.

• Work across native Android and React Native platforms to deliver seamless and intuitive experiences.
• Collaborate closely with Product, Design, Data, and Behavioral Science teams to deliver features that support daily habit formation, long-term motivation, and improved health outcomes.
• Own the implementation of upcoming flagship initiatives 
• Help shape the architectural decisions and technical standards for our Android and React Native applications.

• Bonus: Experience working in health, wellness, or behavior-change-driven apps.

Qualifications

• 10+ years of experience in Android app development.
• 3+ years of React Native experience a plus, with an understanding of where cross-platform vs. native trade-offs make sense.
• Deep knowledge of the mobile development lifecycle and architecture best practices.

• Strong collaboration skills with cross-functional teams and the ability to clearly articulate trade-offs and decisions.
