Cantina bots are lifelike, social creatures, capable of interacting wherever humans go on the internet. Recreate yourself using powerful AI, imagine someone new, or choose from thousands of existing characters. Bots are a new media type that offer a way for creators to share infinitely scalable and personalized content experiences combined with seamless group chat across voice, video, and text.

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

  • Strong programming skills in Python and experience with deep learning frameworks (TensorFlow, PyTorch), along with knowledge of distributed training and inference optimization.

  • Ability to work independently and collaboratively in a fast-paced, dynamic environment, with a strong sense of ownership and drive to deliver impactful results.
