About the job

Synthesia is seeking a Staff Research Scientist to join their R&D department, focusing on the frontier of generative AI, specifically interactive video diffusion models for avatars. This role involves shaping the future of AI video agents that can engage in natural, real-time conversations, understanding and reacting to user input like humans. The team moves quickly, iterating on research to develop product capabilities that are shipped to users.

Responsibilities

  • Set research direction and roadmap for dyadic interaction modeling, balancing long-term research with near-term product impact.
  • Advance state-of-the-art in perceptual layers of interactive agents, including understanding user audio/video and generating appropriate reactions.
  • Post-train multimodal models to generate natural dyadic interactions from user audio and video inputs.
  • Adapt diffusion models to new conditioning signals like conversational state and turn-taking.
  • Build robust evaluation frameworks and test suites for tracking interaction quality.
  • Partner with the data team to define data needs and shape high-quality datasets.
  • Lead and mentor a small group of researchers and drive technical decisions across research, data, and engineering.

Requirements

  • Deep ML expertise and extensive hands-on experience with diffusion models, ideally for video or avatar generation.
  • Strong publication record at top-tier venues in relevant AI fields or equivalent demonstrated impact.
  • Experience leading a small team of researchers and mentoring junior members.
  • Track record of taking research from idea to production.
  • Proficiency in PyTorch and modern ML tooling for large-scale training.
  • Clear communication of hypotheses, experiments, and results, and ability to influence cross-team direction.

Benefits

  • Competitive compensation
  • Hybrid work setting with offices in London, Amsterdam, Zurich, Munich, or remote in Europe.
  • 25 days of annual leave + public holidays
  • Great company culture
  • Option to join regular planning and socials at hubs
  • Other benefits depending on location
