• Work on cutting-edge foundation models that bridge generative video and real-time interaction at the frontier of AI.
• Join a well-funded Series B startup backed by premier global venture capital firms with a high-growth trajectory.
• Transition research directly into production systems, seeing your work reach millions of users rather than staying in papers.

• Research and develop multimodal conversational models to control expressive digital behaviors in real-time with sub-second latency.
• Fine-tune audio-visual foundation models to improve responsiveness, controllable expressions, and task-specific performance.
• Partner with applied machine learning teams to migrate research prototypes into high-performance, scalable production pipelines.

• PhD or equivalent research experience in Deep Learning, specializing in Large Multimodal Models or Generative AI.
• Expert-level proficiency in PyTorch and experience building complex deep learning pipelines for audio or video understanding.
• Proven track record of high-impact research, ideally with a history of publications at top-tier venues like NeurIPS, CVPR, or ICLR.
