▸about Cantina (Spearbit) — company background

About Cantina:

Cantina Labs is a social AI company, developing a suite of advanced real-time models that push the boundaries of expression, personality, and realism. We bring characters to life, transforming how people tell stories, connect, and create. We build and power ecosystems. Cantina, our flagship social AI platform, is just the beginning.

If you're excited about the potential AI has to shape human creativity and social interactions, join us in building the future!

About the Role: We’re looking for a Member of Technical Staff with hands‑on experience building large‑scale video generation models—from data and training to distillation and acceleration into a fast, production‑ready model. Our models are human‑centric and product‑oriented: think interactive characters that can respond to text/audio/image inputs and generate video with very low latency.

This is an applied research + engineering role: you’ll work on training runs, data, model optimization, and the “make it fast” path that turns a capable research model into a real‑time experience.
