Senior/Principal Mobile Software Engineer

Senior Mobile Software Engineer (iOS)

San Diego, CA (Hybrid on-site 3x per week)

A venture-backed medical device startup in San Diego is hiring a Senior Mobile Software Engineer to own its patient-facing mobile app, with iOS as the primary focus, along with the app’s connection to a Bluetooth-connected wearable medical device and the cloud. The product has reached clinical studies, and the company is now scaling toward commercial launch.

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

What You Bring

• 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)
