Job Description
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. Beyond model development, the role involves managing recurring data processes, building predictive and forecasting models, and contributing to data infrastructure modernization.
The position requires collaborating with cross-functional teams, translating model outputs into actionable recommendations, and communicating complex concepts to diverse audiences.
Key Responsibilities:
- Agentic Development: Design AI agent systems that automate analytical workflows, including data retrieval, impact analysis, and proactive recommendation generation.
- Multi-Model Architecture: Decide how to combine LLMs, traditional ML models, and rule-based logic into reliable, end-to-end agent workflows, and build the orchestration layer that ties them together.
- 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.
