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.
