About the job

Synthesia is seeking a Research Scientist to join their R&D department, focusing on the frontier of generative AI, specifically avatar-centric, interactive video diffusion models. This role offers a unique opportunity to shape the future of AI video agents capable of natural, real-time conversations, understanding user input, and responding with human-like reactions. The team operates in a fast-paced environment, translating breakthrough research into tangible product capabilities.

Responsibilities

  • Contribute to research direction and own research problems in dyadic interaction modeling.
  • Advance the state of the art in the perceptual layer of interactive agents, including understanding and generating reactions from user audio and video.
  • Post-train multimodal models for natural dyadic interactions.
  • Adapt diffusion models to new conditioning signals like conversational state and turn-taking.
  • Build robust evaluation frameworks for interaction quality.
  • Define data needs and shape high-quality datasets with the data team.
  • Run rigorous experiments and share findings to inform technical decisions.

Requirements

  • Strong ML background with hands-on experience in diffusion models, preferably for video or avatar generation.
  • Publications at top-tier venues in relevant AI fields or equivalent demonstrated impact.
  • Experience translating research ideas into working implementations and a motivation to see them reach production.
  • Proficiency in PyTorch and modern ML tooling for large-scale training.
  • Clear communication of hypotheses, experiments, and results.

Benefits

  • Build production-scale video foundation models.
  • Work on human-centric video generation with real-world impact.
  • Tackle hard problems in scaling, stability, and controllability.
  • Influence the direction of next-generation synthetic human technology.
  • Join a highly technical, high-ownership environment where your work ships.
