IOS Engineer, Mobile Voice Agents
Role summary
We are seeking an experienced iOS Engineer to build a novel voice agent system on the iOS platform. This role involves owning the complete audio pipeline, from capture to transcription and playback, and optimizing on-device transcription performance and accuracy. You will also be responsible for integrating with Siri and system-level invocation flows, handling real-time audio response playback, and bridging native audio systems with the UI. The ideal candidate is comfortable working within strict platform constraints, debugging complex real-world issues, and has a strong understanding of audio systems and device behavior. Experience with real-time systems and audio pipelines is a plus.
iOS is the hardest environment to build this product.
No background wake word.
No cross-app access.
Strict platform constraints.
We’re building a voice agent system anyway.
What we’re building
A system where users can say:
“Hey Siri, get me a table at Rosario’s for two at 7pm Sunday — if they’re booked, find an alternative and confirm it.”
…and it executes.
What you will own
- audio pipeline (capture → transcription → playback)
- on-device transcription performance and accuracy
- Siri / system-level invocation flows
- real-time audio response playback
- bridging native audio systems to UI
- handling real-world edge cases (interruptions, device changes, latency)
Constraints (non-negotiable)
You'll build within the realities of the iOS platform — App Store compliance, user-invoked flows, and production-grade reliability under real-world conditions. No shortcuts. Everything ships.
Ideal candidate
You:
- have shipped iOS apps to the App Store
- understand audio systems and device behavior
- care about latency and responsiveness
- are comfortable working within strict constraints
- can debug complex real-world issues
Bonus:
- experience with audio pipelines or real-time systems
- experience bridging native systems with cross-platform UI
What you’ll be doing early
- building the full audio pipeline
- implementing system-level invocation flows
- ensuring fast, natural audio playback
- handling edge cases across devices and environments
Compensation
Equity-only (founding team)
This is not a typical iOS app.
You are building within constraints to enable a new interaction model.
