Experience

5+ years of total IT experience, including 2–3 years in AI/ML or Generative AI development. Must have hands-on experience building, testing, and deploying LLM-based or agentic AI applications in production or pilot settings.

Role Overview

The Senior Associate – Generative AI Developer will design, develop, and rigorously test end-to-end Generative AI and agentic AI applications. This role requires hands-on expertise with LLM APIs, RAG pipelines, prompt engineering, and multi-agent frameworks, combined with a disciplined approach to testing, performance monitoring, and optimization .

Key Responsibilities

  • LLM & GenAI Development: Design, develop, and maintain LLM-powered applications using APIs such as OpenAI, Azure OpenAI, Anthropic, or Cohere. Implement core GenAI workflows including summarization, classification, Q&A, and content generation.
  • Agentic AI Implementation: Build and orchestrate multi-agent systems using frameworks like CrewAI, LangGraph, OpenAI Agents SDK, or Azure AI Agent Framework . Implement inter-agent communication, task routing, and tool orchestration for complex workflows.
  • RAG & Embedding Pipelines: Implement retrieval-augmented generation pipelines involving embedding creation, chunking, and vector indexing using FAISS, Pinecone, Chroma, or Milvus . Ensure efficient retrieval for context-aware outputs.
  • Prompt Engineering & Techniques: Apply advanced prompting strategies such as Few-Shot Learning, Chain-of-Thought (CoT), ReAct, and CART to improve reliability and interpretability of model responses.
  • Testing & Validation: Establish automated and manual testing pipelines using TruLens , LangSmith , PromptLayer , or DeepEval to evaluate model quality, accuracy, safety, and factual grounding. Define and track metrics such as coherence, hallucination rate, and response diversity.
  • Performance Monitoring & Optimization: Implement cost-effective token management and model observability using logging and tracing frameworks. Continuously optimize prompts, retrieval logic, and memory mechanisms to improve efficiency.
  • Data Analysis & Preparation: Conduct EDA and pre-processing of textual datasets to ensure quality input for training, evaluation, and fine-tuning tasks.
  • Documentation & Collaboration: Create detailed design documents, maintain experiment logs, and collaborate with architects, data scientists, UI/UX engineers, and product managers to ensure solution alignment with business goals.
  • Continuous Learning: Stay up to date with new model releases (OpenAI GPT, Claude, Gemini, Mistral, LLaMA, etc.) and frameworks in the GenAI and agentic AI ecosystem.

Key Skills & Competencies

  • Strong proficiency in Python , LangChain , LlamaIndex , CrewAI , and LangGraph
  • Deep understanding of LLM architectures , tokenization , embedding models , and vector databases
  • Experience with prompt testing and evaluation frameworks (TruLens, LangSmith, PromptLayer, DeepEval)
  • Familiarity with bias mitigation , safety testing , and Responsible AI principles
  • Knowledge of MLOps/LLMOps practices for deploying and monitoring AI models
  • Strong analytical mindset, documentation discipline, and collaborative approach
  • Exposure to at least one major cloud AI platform ( Azure , AWS , GCP , or OCI )

Preferred Background

Prior experience in building chatbots, intelligent assistants, summarizers, or document automation solutions using LLMs

Familiarity with open-weight model experimentation (LLaMA, Mistral, Falcon, etc.)

Exposure to multi-modal AI (text, image, code) and integration with enterprise data sources

Experience supporting GenAI projects through testing, benchmarking, and performance optimization
