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.

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.

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

Experience building and deploying machine learning models to production, focusing on modular, scalable, and maintainable models.
Hands-on experience with LLMs or generative AI, with demonstrated interest or experience in building agentic or multi-model systems.
Comfortable building data pipelines and working with large-scale data using tools like Spark, Airflow, SQL, or Python.
Experience managing data science or ML projects from scoping through delivery.

Experience with predictive modeling and time-series forecasting.
