Our goal: make talking to AI feel like conversing with the most charming, kind, and knowledgeable person imaginable.

We’re seeking exceptionally smart, execution-oriented engineers to help us get there.

Build and iterate a comprehensive evaluation framework covering objective metrics (accuracy, quality, latency, expressiveness), human preference studies, content factuality assessments, real-time interaction quality, and experimentation infrastructure to measure and improve performance.

Work closely with product teams to integrate voice models into applications and real-time environments, define spoken interaction specifications, and handle the full lifecycle from prototype to global-scale deployment for stable, low-latency, delightful voice experiences.
