Job Description
Machine Learning Researcher
Brahma
• Research and develop cutting-edge generative video models, with a focus on controllable facial expression, head motion, and audio-driven lip synchronisation. • Fine-tune and extend video diffusion models such as WAN and Hunyuan for better visual realism and audio-visual alignment. • Design robust training pipelines and large-scale video/audio datasets tailored for talking-head synthesis. • Explore techniques for controllable expression editing, multi-view consistency, and high-fidelity lip sync from speech or text prompts. • Work closely with product and creative teams to ensure models meet quality and production constraints. • Stay current with the latest research in video generation, speech-driven animation, and 3D-aware neural rendering.
Job Requirements
- Strong background in machine learning and deep learning, especially in generative models for video, vision, or speech.
- Hands-on experience with video synthesis tasks such as face reenactment, lip sync, audio-to-video generation, or avatar animation.
- Proficient in Python and PyTorch; familiar with libraries like MMPose, MediaPipe, DLIB, or image/video generation frameworks.
- Experience training large models and working with high-resolution audio/video datasets.
- Deep understanding of architectures such as transformers, diffusion models, GANs and motion representation techniques.
- Proven ability to work independently and drive research from idea to implementation.
- Strong problem-solving skills, ability to work autonomously in a remote-first environment.
