## About the Role

* BS in Computer Science, Software Engineering or a related field
 * 5-8+ years of software engineering experience, including significant native mobile development
 * Have published at least one app to the Apple App Store, with an understanding of the review process, provisioning profiles, and build and deployment schemes
 * Strong native iOS development (Swift, SwiftUI/UIKit); Android (Kotlin) is a plus
 * Comfortable designing to Apple's Human Interface Guidelines (HIG); familiarity with Liquid Glass design principles is a plus
 * Strong grasp of mobile architecture, background execution, local storage and offline-first design
 * Experience integrating with REST APIs and cloud services
 * Nice to have: Core Bluetooth/BLE or wearable hardware, HealthKit, push notifications and critical alerts, and medical device or regulated environments (IEC 62304)

## Description

You'll think holistically about how users experience their therapy day to day, how the app communicates with the device, and how failures are detected and handled, while staying hands-on in architecture, implementation and debugging.
What You'll Do

 * Own the architecture, design and implementation of the mobile app, from requirements through release
 * Lead key workflows, including onboarding, device pairing, therapy features, alerts and data visualization
 * Build reliable BLE communication between the app and the wearable device, including pairing, reconnection and background operation
 * Integrate the app with cloud services and APIs for data sync, notifications and remote monitoring
 * Set standards for code quality, testing and CI/CD, and support release cycles and App Store submissions
 * Contribute to design controls, risk analysis and verification for software as a medical device, and mentor other engineers
