Lead Data Scientist

YOUR ROLE

We are seeking an experienced Lead Data Scientist with strong expertise in Machine Learning, Recommender Systems, and Generative AI (LLM & Large Vision Models). The role provides technical leadership in designing, developing, deploying, and scaling enterprise AI solutions while collaborating closely with Data Engineering, ML Engineering, Platform Engineering, and business stakeholders. The ideal candidate will drive AI solution architecture, mentor technical teams, establish best practices, and ensure scalable, secure, production-ready AI implementations.

Key Responsibilities

Data Science & Advanced Analytics — Lead end-to-end ML solutions from ideation to production. Drive EDA, feature engineering, model evaluation, and optimization. Develop predictive and prescriptive analytics models. Translate business problems into scalable AI/data science solutions.

Machine Learning Services (Primary Focus) — Design and implement scalable ML pipelines for training, testing, and deployment. Architect enterprise ML platforms using Azure Machine Learning, AWS SageMaker, or Google Vertex AI. Define model lifecycle management (versioning, monitoring, retraining, governance). Optimize models for performance, scalability, and reliability.

Recommender Systems — Lead design of recommendation engines (collaborative filtering, content-based, hybrid). Design ranking, personalization, and segmentation strategies. Define evaluation metrics (Precision@K, Recall@K, MAP, NDCG). Guide scalable recommendation architectures.

Generative AI (LLM & LVM) — Design enterprise GenAI solutions (chatbots, copilots, document intelligence). Architect RAG solutions using OpenAI, Azure OpenAI, or Hugging Face models. Design use cases for text generation, summarization, classification, and image/video understanding. Lead prompt engineering and LLM optimization.

Collaboration with Data Engineering — Define data requirements, ensure data quality, governance, and availability. Work with Spark, Databricks, Hadoop.

ML Engineering & Deployment Support — Deploy models via APIs/microservices, containerize (Docker, Kubernetes), and integrate into production systems and CI/CD pipelines.

Model Monitoring & Governance — Monitor model drift, performance degradation, and bias. Implement logging, alerting, explainability tools, and Responsible AI practices (fairness, transparency, interpretability).

Qualifications & Experience

8+ years in Data Science, ML, AI, or Advanced Analytics, with 5+ years hands-on deploying enterprise ML solutions. Proven experience leading end-to-end AI initiatives from concept to production, designing scalable AI architectures, mentoring technical teams, and delivering AI solutions in Agile environments on enterprise cloud platforms.

YOUR PROFILE

Education: B.Tech/B.S./M.S. in Computer Science, Statistics, Mathematics, or related field.
