• Architect robust systems for scalable evaluation and annotation, including prompt‑based scoring, perceptual metrics, caption generation, and retrieval‑based diagnostics.
• Collaborate with model researchers to co‑design video model architectures (e.g. DiTs, VAEs, spatio‑temporal transformers) and training schedules across pretraining and fine‑tuning stages.
• Optimize distributed data loading and pipeline throughput for training at scale, ensuring robustness across model variants and modality combinations.
• Manage infrastructure to support experiment tracking, model versioning, and cross‑team deployment workflows, integrating with production and research platforms.
• Support backend engineering across research, product, and creative teams to ensure seamless integration of data and model workflows from prototyping to inference.

• Proficient in Python with strong programming skills across backend, infrastructure, and data tooling domains.
• Strong software engineering experience, including 2+ years working with petabyte‑scale data pipelines and systems across thousands of GPUs.
• Proven ability to architect and maintain large‑scale distributed systems for data processing and delivery.
• Deep expertise in orchestration frameworks such as Kubernetes and SLURM with hands‑on experience deploying and managing high‑throughput workloads.

Preferred Qualifications

• Practical experience on building pipelines and infrastructure with visual and multimodal datasets, including image/video pipelines.
• Experience in building video foundation infrastructure pipelines and workflows with collaboration of LLM and/or video foundation research and engineering teams is a strong advantage.
