Jobs in Barueri, Brasil

We are seeking a skilled Full Stack Mobile Developer to take end-to-end ownership of our flagship mobile application.

As the sole mobile developer, you will be responsible for evolving an app that pairs with a Bluetooth-enabled pulse oximeter ring to capture overnight sleep data and securely upload it to the cloud. You won't be working in isolation—while you'll lead all mobile-focused design and development, you'll collaborate closely with a team of experienced C# / NET backend engineers.

You’ll also contribute to backend features related to sleep‑study processing and data workflows, helping shape the overall product experience from device integration through clinical‑grade data analysis. This is an opportunity to own a critical mobile product in a modern health‑tech environment, working with senior engineers to deliver technology that directly impacts patient outcomes.

The ideal candidate will have expertise in both mobile development (Flutter / Dart) and backend technologies (C# / NET), and be capable of ensuring seamless device integration, reliable overnight data collection, and robust backend connectivity with Azure services.

• Lead the development and maintenance of cross‑platform mobile applications using Flutter / Dart for iOS and Android.
• Implement and optimize Bluetooth connectivity with the ring pulse oximeter device.
• Address Android battery optimization challenges to guarantee reliable overnight data collection.
• Manage the release process for both the Apple App Store and Google Play Store.
• Collaborate with backend developers on Azure‑hosted .NET services, contributing to backend development when required.
• Ensure compliance with health data security and privacy standards.
• Work independently while providing technical leadership within the team.
