Essential Functions & Key Responsibilities

• GenAI Application Development: Design, develop, and deploy LLM-powered applications such as intelligent assistants, document summarization, and workflow automation, using frameworks like LangChain or LlamaIndex and models from providers such as OpenAI, Anthropic, or Azure OpenAI.
• Retrieval-Augmented Generation (RAG): Architect and implement RAG pipelines using vector databases (e.g., Pinecone, FAISS, pgvector), embedding models, and chunking strategies to ground model outputs in enterprise data.
• Prompt Engineering & Evaluation: Craft, test, and iterate on prompts and agentic workflows, and establish evaluation frameworks to measure accuracy, relevance, hallucination rates, and latency.
• Python Backend & API Development: Build scalable Python services and RESTful APIs using FastAPI or Flask, with clean, well-tested, and maintainable code.
• Data Engineering & Pipelines: Develop data ingestion and transformation pipelines using Pandas, SQL, and cloud-based data services to prepare structured and unstructured data for AI workloads.
• Cloud Deployment & MLOps: Deploy and monitor AI solutions on cloud platforms (AWS, Azure, or GCP) using Docker, CI/CD pipelines, and observability tooling to ensure reliability and cost efficiency.
• Responsible AI & Security: Implement guardrails, data privacy controls, and governance practices that align with client security, model risk management, and regulatory compliance standards.
• Agile Collaboration: Participate actively in Agile ceremonies (sprint planning, daily stand-ups), track work in Jira and collaborate with cross-functional teams to translate business needs to AI-enabled solutions.
