Research Scientist (Singapore)
Job Summary
About Cantina:
Cantina Labs is a social AI company developing a suite of advanced real-time models that push the boundaries of expression personality and realism. We bring characters to life transforming how people tell stories connect and create. We build and power ecosystems. Cantina our flagship social AI platform is just the beginning.
About the Role:
Cantina is expanding and were looking for a Research Scientist to join our growing Singapore team! In this role you will drive foundational research on video generation models taking ownership across the full research cycle and driving post-training research. Furthermore youll collaborate closely with data infrastructure and adjacent modeling teams to translate research findings into durable model improvements.
What Youll Do:
Build and maintain scalable systems for ingesting preprocessing and delivering large-scale video data for model training
Design and scale distributed data pipelines for preprocessing dataset generation and repeated dataset refreshes
Own workflow orchestration job scheduling monitoring and failure recovery for large-scale data processing jobs
Implement and maintain containerized pipeline infrastructure using Kubernetes or equivalent orchestration systems
Optimize cloud-based data storage and movement across providers (AWS GCS or Azure) for cost throughput and operational efficiency
Define and implement best practices for dataset storage layout versioning caching retention and access patterns
Build tooling to support deduplication workflows at scale including near-dedup pipelines over large video corpora
Research and develop distillation methods for large-scale diffusion and flow-based video generation models including guidance distillation and adversarial distillation with a focus on preserving or improving generation quality while reducing inference cost
Develop reward models and preference-based fine-tuning pipelines that align video generation quality with human judgments across dimensions such as aesthetics motion quality and prompt adherence
Analyze the relationship between base model behavior and post-training outcomes and work with the foundation model team to inform pretraining decisions accordingly
What Youll Bring:
Strong hands-on experience building or scaling large-scale data systems or pipelines for machine learning workflows
Experience with distributed data processing frameworks such as PySpark or Ray and orchestration tools such as Airflow or equivalent
Familiarity with containerization and container orchestration including Docker and Kubernetes
Experience working with cloud-based data storage and compute (AWS GCS and/or Azure) including tradeoffs around cost throughput storage layout and access patterns
Familiarity with video and media processing tools such as FFmpeg PyAV DALI or OpenCV
Familiarity with multimodal or media data including video image text and audio
Strong research background in post-training methods for large-scale diffusion or flow-based generative models with deep hands-on experience in distillation across both inference efficiency and quality preservation
Experience with reward modeling or preference-based fine-tuning for generative models including RLHF DPO or equivalent alignment approaches
Solid understanding of the interplay between pretraining and post-training and how base model properties affect distillation and fine-tuning outcomes
Proficiency in Python and modern machine learning frameworks with a strong preference for PyTorch or JAX
Track record of independent research with the ability to drive projects from initial idea through experimental validation
Publications at top-tier venues (NeurIPS ICML ICLR CVPR ICCV ECCV) preferred
Good understanding of the practical challenges involved in building reliable scalable and reproducible data workflows for machine learning systems
