Realtime Voice Engineer

Quippy (YC F26) is a daily practice room for the conversations people dread. You pick a real situation, like disagreeing with your manager or starting a conversation at a party, rehearse it with a realistic scene partner by voice or text, and get honest, line-by-line feedback on what landed. The app is live on the App Store.

Voice is the part of Quippy people remember, and the hardest part to build. You will own the realtime path from someone's microphone to a scene partner's reply and back, and make it quick enough that people forget they are practicing.

What you will work on

• Own the realtime voice pipeline across the iOS app and the backend

• Cut latency, handle interruptions and turn-taking, and make audio sound right on every device

• Measure conversation quality and fix what makes it feel robotic

• Build the tools that let us test voice changes before they reach users

You might be a fit if

• You have shipped realtime audio, voice, WebRTC, or streaming systems

• You care about milliseconds and can find where they go

• You can debug across the network, the phone, and the server

• You want to build something people talk to every day

Why join now
