Hands-on with data quality, compliance, and governance frameworks.
Familiarity with security best practices in AWS environments.
Experience with data enrichment or summarization using LLMs.
Familiarity with RAG pipelines, vector databases (e.g., OpenSearch, Pinecone, FAISS), and metadata extraction using LLMs.

Key Responsibilities
Design & Build Intelligent Data Solutions: Develop and maintain scalable, LLM-enabled data pipelines using AWS services like Glue, Redshift, Lambda, Step Functions, S3, Athena, and ECS.
Integrate LLM APIs or fine-tuned models (e.g., OpenAI, HuggingFace, Amazon Bedrock, SageMaker JumpStart) into existing AWS-based data workflows.
Enable RAG (Retrieval-Augmented Generation) pipelines using AWS services and LLMs for advanced analytics and knowledge management.
ETL Development: Build efficient, reusable ETL frameworks that can incorporate LLMs for data enrichment, summarization, classification, or metadata generation.
Use orchestration tools like Airflow/MWAA or Step Functions to manage both data and LLM workflows.
LLM & AI Services in AWS: Work with Amazon Bedrock, SageMaker, or custom containers to deploy, monitor, and scale LLM-based solutions.
Optimize LLM usage for performance and cost within the AWS ecosystem (e.g., caching responses, throttling, model selection).
Data Security & Integrity: Implement security best practices and compliance standards for handling sensitive data within LLM pipelines.
Ensure proper prompt auditing, logging, and governance for LLM interactions.
Monitoring & Troubleshooting: Continuously monitor pipelines (including LLM calls), troubleshoot failures, and optimize performance and cost.
Documentation: Maintain detailed documentation of data architectures, frameworks, and engineering processes.
Architecture & Reviews: Participate in solution architecture, code reviews, and sign-offs to ensure quality and scalability.
