Senior Native iOS Audio Engineer (SwiftUI / AVFoundation)

Hi, I’m building a premium native iOS product where audio performance and playback quality are central to the user experience. I’m looking for a senior native iOS engineer with strong AVFoundation experience to help build the first production-quality MVP. This is an audio-first product where smooth playback, seamless transitions, background reliability and native iOS behavior are critical. — Core scope (V1) • Voice recording flow • Voice/audio processing integration • Structured multi-segment audio playback • Seamless transitions between audio layers • Background playback • Lock screen media controls • Clean native SwiftUI architecture — Technical requirements • Native iOS development only (SwiftUI) • Strong AVFoundation experience • Experience with background audio + media controls • Experience optimizing playback reliability • Strong understanding of native iOS audio behavior Preferred: • Experience with meditation, sleep, music or audio-focused apps • Experience with lock screen playback + interruptions • Experience building polished consumer-facing products — Important Please do not apply if your background is primarily: • React Native • Expo • Flutter • Web-focused development This role is specifically for developers with strong native iOS audio experience. I care much more about playback quality, clean architecture and reliability than shipping fast with the wrong stack. — Engagement We’ll start with a small paid test sprint (10–15 hours) focused on audio playback architecture and implementation quality. If the collaboration is strong, the project will continue into a larger MVP build. — To apply Please briefly explain: 1. Your experience with AVFoundation 2. How you typically handle background playback in iOS 3. Your approach to seamless audio transitions 4. Examples of audio-related work you’ve built 5. Links/screenshots/examples if available Looking forward to hearing from you.
