Senior iOS Developer

Company Description

Bright is building the super app for health, a unified operating system designed to empower individuals through comprehensive, personalised health tracking and insights.

Bright bridges food and health in a way no other app does. Our launch product supports tracking across more than 750 health data points, spanning nutrition, sleep, activity, recovery, vitals, and more. Users can log meals, monitor micro and macronutrients, track heart patterns, understand stress and strain, manage body recomposition, and receive personalised insights, all in one place.

We believe health should function as a dynamic feedback loop, where your data does not sit in silos but actively informs your next best decision.

Today’s health apps are fragmented. Users juggle multiple tools that do not communicate with each other, leaving important insights on the table. Bright solves this by integrating lifestyle, biometric, and clinical inputs into one seamless system that delivers clarity and actionable guidance.

Our mission is to become the last health app anyone needs, one that grows with you and supports every step of your health journey, from everyday wellness to advanced care.

If you are passionate about building products that improve lives and want to help shape the future of health through technology, we would love to hear from you.
