About the role

Develop computer vision and multimodal AI solutions for complex problems across eBay's global marketplace.

The team adapts and extends foundation models for specialized problems at scale where existing models and off-the-shelf methods fall short.

Projects span personalized experiences and recommendations, content intelligence, attribute extraction, visual recognition, anomaly detection, and multimodal inventory understanding.

The role takes problems from early investigation through research, model development, evaluation, and production deployment.

Work arrangement

  • Hybrid role requiring presence in the Toronto office three days per week.

What you will do

  • Develop and deploy visual and multimodal models for recognition, visual understanding, content intelligence, retrieval, and decisioning.
  • Design and optimize production training and inference pipelines, including orchestration of models and services.
  • Advance detection, segmentation, classification, metric and contrastive learning, and visual-language modeling capabilities.
  • Lead research initiatives, adapt foundation models, and develop specialized architectures, data strategies, training methods, and evaluation approaches.
  • Lead work on visual-language model training and fine-tuning, model distillation, reinforcement learning, and other modern AI methods.
  • Partner with product, engineering, design, and applied science colleagues to turn business opportunities into technical roadmaps and delivered solutions.
  • Communicate technical direction and trade-offs to stakeholders, and mentor researchers and other team members.

Qualifications

  • Ph.D. or M.S. in Computer Science, Electrical Engineering, Machine Learning, Applied Mathematics, or a related technical field focused on computer vision, multimodal AI, or artificial intelligence.
  • At least three years of experience building computer vision and/or multimodal systems for large-scale applications.
  • Experience taking machine learning solutions from research through production, including training, evaluation, and inference pipelines and model integration.
  • The role calls for leadership of ambiguous research problems, stakeholder communication, and mentoring.
