What we are looking for

We’re looking for a deeply technical, product-driven applied scientist to help scale and operationalize our ADFA and lip sync work. This role exists to support and amplify ongoing research by owning model training pipelines, metrics, evaluation, and data workflows. This will be ensuring our lip sync models improve reliably with every release. You’ll operate at the intersection of research and production, bringing rigor, automation, and clarity to how we validate and ship model improvements.

Responsibilities

• Model Development & Training
  • Develop repeatable, scalable ADFA model training workflows across multiple datasets
  • Train, fine-tune, and manage lip sync model variants as trackers, data, and architectures evolve
  • Incorporate new datasets and model updates as they become available
• Evaluation, Metrics & Quality
  • Design, automate, and maintain ADFA metric testing pipelines
  • Generate new quantitative and qualitative metrics to evaluate lip sync quality
  • Produce comparisons, visualizations, and analyses to inform research and product decisions
• Collaboration & Support
  • Partner closely with ADFA researchers to support ongoing and future research initiatives
  • Validate lip sync quality to improve out-of-the-box approval rates and reduce downstream cost and iteration time
  • Collaborate with Science, Engineering, and Product teams to align research outputs with company goals

Qualifications

• MSc OR PhD + Industry experience working in the domains of 3D Computer Vision, Speech Synthesis, Computer Graphics, or related field
• Proficiency in Python, with a strong foundation in computer science and problem-solving.
• Expertise with deep learning frameworks (PyTorch) and vision tools (OpenCV).
• A strong product mindset — motivated by building systems that deliver tangible value to users, not just technical novelty.
• Comfortable working at both the algorithmic and implementation levels, from model design and optimisation to large-scale data processing and integration in production systems.
• High degree of proficiency in math and statistical methods for signal processing
• Experience with audio-visual learning, multimodal fusion, and/or 3D audio-driven face animation
• Experience with speech modeling and speech synthesis with deep neural networks
• Outstanding communication skills for collaboration with scientists, research/ML engineers, and VFX artists

Bonus points for

• Demonstrable research experience with a strong publication record in major 3D Computer Vision, Speech Processing, and Computer Graphics venues and journals (e.g., CVPR, SIGGRAPH, NeurIPS)
• Experience developing multi-modal systems that integrate audio, text, and visual inputs.
• Experience working with cross-functional teams
• Experience with generative and cross-domain attention models for 3D visual speech synthesis applications
