About this role
**Key Responsibilities: **
* Architect and implement scalable AI Agents, Agentic Workflows and GenAI applications to address diverse and complex business use cases.
* Develop, fine-tune, and optimize lightweight LLMs; lead the evaluation and adaptation of models such as Claude (Anthropic), Azure OpenAI, and open-source alternatives.
* Design and deploy Retrieval-Augmented Generation (RAG) and Graph RAG systems using vector databases and knowledge bases.
* Curate enterprise data using connectors integrated with AWS Bedrock's Knowledge Base/Elastic
* Implement solutions leveraging MCP (Model Context Protocol) and A2A (Agent-to-Agent) communication.
* Build and maintain Jupyter-based notebooks using platforms like SageMaker and MLFlow/Kubeflow on Kubernetes (EKS).
* Collaborate with cross-functional teams of UI and microservice engineers, designers, and data engineers to build full-stack Gen AI experiences.
* Integrate GenAI solutions with enterprise platforms via API-based methods and GenAI standardized patterns.
* Establish and enforce validation procedures with Evaluation Frameworks, bias mitigation, safety protocols, and guardrails for production-ready deployment.
* Design & build robust ingestion pipelines that extract, chunk, enrich, and anonymize data from PDFs, video, and audio sources for use in LLM-powered workflows leveraging best
practices like semantic chunking and privacy controls
* Orchestrate multimodal pipelines** using scalable frameworks (e.g., Apache Spark, PySpark) for automated ETL/ELT workflows appropriate for unstructured media
* Implement embeddings drives map media content to vector representations using embedding models, and integrate with vector stores (AWS KnowledgeBase/Elastic/Mongo
Atlas) to support RAG architectures
**Required Qualifications:**
* PhD in AI/Data Science
* 10+ years of experience in AI/ML, with 3+ years in applied GenAI or LLM-based solutions.
* Deep expertise in prompt engineering, fine-tuning, RAG, GraphRAG, vector databases (e.g., AWS KnowledgeBase / Elastic), and multi-modal models.
* Proven experience with cloud-native AI development (AWS SageMaker, Bedrock, MLFlow on EKS).
* Strong programming skills in Python and ML libraries (Transformers, LangChain, etc.).
* Deep understanding of Gen AI system patterns and architectural best practices, Evaluation Frameworks
* Demonstrated ability to work in cross-functional agile teams.
* Need Github Code Repository Link for each candidate. Please thoroughly vet the candidates.
