Software Engineer, iOS & Android

What You'll Do:

• Own Era's consumer app for iOS and Android - a production SwiftUI app with native state management, CoreBluetooth device connectivity, audio pipelines, live activities, and secure authentication
• Build and maintain the app-side BLE device layer - custom protocol communication with Era hardware, real-time audio streaming, multi-device concurrent connections, auto-reconnection
• Own the real-time voice pipeline on-device - microphone capture, encoding, WebRTC streaming to our cloud intelligence layer, and TTS audio playback
• Implement cross-device state and context. A user's active conversation, memory, and device configuration should feel continuous across all their devices
• Build the Android counterpart. As Era's device ecosystem expands, own the strategy and initial build for Android
• Craft every interaction - animations, transitions, haptics, the details that make an app feel alive

What We're Looking For:

• Strong iOS development experience with SwiftUI. You've shipped native apps that real people use daily
• Hands-on CoreBluetooth / BLE experience. You've built device communication layers, dealt with GATT characteristics, handled connection state machines
• Experience with real-time audio on mobile - audio session management, codec integration, or streaming pipelines
• An eye for polish. You care about animation curves, gesture responsiveness, and the 100 other small details that separate a good app from one people love
• Experience with authentication flows in native apps
• A portfolio of apps you've built. We'd love to see them

Nice to Have:

• Experience building companion apps for hardware products - wearables, IoT, audio devices
• Android / Kotlin experience
• watchOS or multi-platform Apple development experience
• On-device ML or edge AI experience - local inference, CoreML, audio classification
• Experience with CI/CD for mobile - fastlane, TestFlight automation.
