Job Level
About the role
- Design and execute experiments to improve multimodal embedding model quality, spanning model architecture, training methodology, data composition, and evaluation
- Build and optimize large-scale distributed training pipelines (multi-node, multi-GPU) for contrastive and representation learning
- Develop and improve data curation, filtering, and quality assessment pipelines at scale
- Conduct ablation studies to systematically evaluate design choices and communicate findings to guide technical direction
- Implement evaluation frameworks and benchmarks that rigorously measure embedding model quality
- Collaborate with the search/serving team to ensure model improvements translate to end-to-end retrieval quality gains
Requirements
- 4–7 years of industry experience in computer vision, NLP, or multimodal learning, with a track record of shipping ML systems to production
- Strong proficiency in Python and PyTorch, with hands-on experience in distributed model training
- Experience in contrastive learning, representation learning, or embedding models, demonstrated through shipped products, publications, or open-source contributions
- End-to-end ownership experience: taking a model from research idea through training to production deployment, not just running experiments in isolation
- Ability to independently drive research projects from problem definition through experiment design to conclusions
- Effective communication skills for collaborating with colleagues from diverse backgrounds
