Lead Data Scientist

About the Role

We are looking for a Lead Data Scientist – Agentic AI to lead the design, development, and productionization of next-generation Agentic AI, Generative AI, Machine Learning, and Advanced Analytics solutions for real-world business problems.

The ideal candidate will combine strong foundations in Statistics, Machine Learning and Data Science with hands-on expertise in LLMs, AI Agents, agentic workflows, RAG, tool calling, multi-agent systems, and AI application engineering.

This is a hands-on technical leadership role. The Lead Data Scientist will be expected to take ownership of complex problems end-to-end — from understanding the business problem and defining the analytical approach to designing the AI architecture, building and evaluating solutions, deploying them to production, and mentoring other Data Scientists.

Prior experience in forecasting, demand planning, supply chain, pricing, promotions, or other CPG/Retail analytics will be an added advantage.

• Establish reusable engineering patterns and best practices for AI applications.

5. Production & Cloud

• Take AI/ML solutions from prototype to production.

• Containerize applications using Docker.

• Deploy AI solutions on AWS, Azure or GCP.

• Work with Platform/DevOps teams on scalable AI architecture.

• Contribute to CI/CD, monitoring, logging and production reliability.

• Diagnose production issues and drive improvements in system performance and reliability.

6. Technical Leadership & Mentoring

• Own complex AI problems from problem definition through production.

• Break ambiguous business problems into executable technical components.

• Mentor and guide Data Scientists and AI Engineers.

• Review modelling approaches, AI architectures and technical implementations.

• Establish technical standards and reusable components.

• Collaborate with Data Engineering, Software Engineering and DevOps teams.

• Work directly with business stakeholders and clients when required.
