The Sr. Data Scientist is responsible for designing and deploying AI-powered tools and agent systems that combine LLMs and custom ML models into end-to-end solutions that support business decision-making.

Prototyping to Production: Take agent prototypes from proof-of-concept through iteration to production-grade systems with proper documentation, testing, CI/CD, and deployment ownership.
Predictive Modeling & Forecasting: Build and maintain forecasting models and other predictive tools that feed into agent systems or support business decisions directly.
Data ETL: Monitor and maintain recurring data processes, ensuring pipelines run on time and data quality stays high.
Data Infrastructure: Contribute to modernizing the data stack by migrating pipelines, expanding data coverage, and supporting cloud migration efforts.
Collaboration & Communication: Work with teammates across regions, product, and engineering, translating model and agent outputs into clear recommendations for senior business stakeholders.

Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager.
