• Collaborer avec les équipes produit, design et ingénierie pour identifier les opportunités d'IA/ML à fort impact.
• Prototyper et mettre en production des systèmes d'IA qui semblent intuitifs mais qui effectuent beaucoup de travail en arrière-plan.

• Deep knowledge of machine learning, deep learning, and applied AI
• Experience adapting or training foundation models (language or multimodal) for novel domains
• A track record of building things that ship—whether it’s recommendations, search, machine translation, or something equally complex
• Experience across the full ML lifecycle: data curation, training, deployment, monitoring
• Bachelor’s degree in Computer Science, Engineering, Mathematics, or a related field (required)
• 10+ years of experience building and deploying production-grade AI/ML systems
• You've built agents that can plan, reason, and use tools
• You know your way around cloud infrastructure (AWS, GCP, Azure)
• You’ve worked in a fast-moving startup or high-growth environment
