How you will do it

Advanced Analytics, LLMs & Modeling

* Design and implement advanced machine learning models including deep
learning, time-series forecasting, recommendation engines, and LLM-based
solutions (e.g., GPT, LLaMA, Claude).
* Develop use cases around enterprise search, document summarization,
conversational AI,



and automated knowledge retrieval using large language
models.
* Fine-tune or prompt-engineer foundation models (e.g., OpenAI, Azure OpenAI,
Hugging Face) for domain-specific applications.
* Evaluate and optimize LLM performance, latency, cost-effectiveness, and
hallucination mitigation strategies for production use.

Data Strategy & Engineering Collaboration

* Work closely with data and ML engineering teams to integrate LLM-powered
applications into scalable, secure, and reliable pipelines.
* Contribute to the development of retrieval-augmented generation (RAG)
architectures using vector databases (e.g., FAISS, Azure Cognitive Search).
* Support the deployment of models using MLOps principles, ensuring robust
monitoring and lifecycle management.

Business Impact & AI Strategy

* Partner with cross-functional stakeholders to identify opportunities for
applying LLMs and generative AI to solve complex business challenges.
