Lead Data Scientist

AI/ML/LLM/RAG Solution Development Architect and implement end-to-end AI/ML solutions, leveraging structured and unstructured data (text, images, metadata, multimodal sources).

Lead development and deployment of LLM-powered systems for classification, retrieval-augmented generation (RAG), information extraction, and summarization.

Apply advanced techniques such as LoRA, PEFT, quantization, and model distillation to optimize model performance, latency, and cost.

Design and implement robust retrieval pipelines with vector search, hybrid retrieval, and reranking strategies.

Technical Excellence & Best Practices Ensure code quality, reproducibility, and model governance across the AI/ML lifecycle — from experimentation to production release.

Establish and promote best practices for data processing, feature engineering, model evaluation, and monitoring.

Conduct rigorous performance benchmarking and failure analysis, ensuring models meet accuracy, throughput, and reliability targets.

Product Lifecycle & Stakeholder Alignment Partner closely with product managers, engineers, and customer-facing teams to translate business needs into AI/ML requirements.

Align model development milestones with product release schedules, ensuring timely and high-quality delivery.

Serve as a technical advisor during project scoping, prioritization, and release readiness reviews.

Research, Innovation & Thought Leadership Stay current with cutting-edge research in AI, ML, NLP, LLMs, multimodal models, retrieval systems, and document intelligence..

Proactively identify opportunities to enhance existing algorithms and develop novel approaches.

Share learnings through internal tech talks, documentation, and mentorship to foster a culture of innovation.
