What you'll do

• Develop and improve multimodal AI systems involving image, video, and generative pipelines.
• Work on diffusion model optimization, controllability, and step efficiency.
• Design experiments and evaluation frameworks for visual realism and consistency.
• Translate research prototypes into scalable production systems.
• Collaborate closely with infrastructure teams to optimize training and inference.

Qualifications

• Degree in Computer Science, AI, Robotics, or comparable combination of education and practical experience.
• Strong programming skills in Python and familiarity with object-oriented languages (C++, Java, or similar).
• Strong data structures and algorithms fundamentals.
• Experience with PyTorch or similar frameworks.
• Familiarity with CNNs, Vision Transformers (ViT), or diffusion architectures.

Preferred Qualifications

• Experience with Stable Diffusion, ControlNet, LoRA, or generative pipelines.
• Human pose estimation, geometry-aware modeling, or video understanding.
• Experience shipping ML systems into production.
