• Implement and Orchestrate Agents: Utilize frameworks like MCP, OpenAI Agent SDK, LangChain, LlamaIndex, Haystack, and DSPy to build dynamic multi-agent systems and serverless GenAI applications.
• Deploy Models at Scale: Manage model deployment using HuggingFace, Azure Web Apps, vLLM, and Ollama, including handling local models with GGUF, LoRA/QLoRA, PEFT, and Quantization methods.
• Integrate APIs: Seamlessly integrate with APIs from OpenAI, Anthropic, Cohere, Azure, and other GenAI providers.
• Ensure Security and Compliance: Implement guardrails, perform PII redaction, ensure secure deployments, and monitor model performance using advanced observability tools.
• Optimize and Monitor: Lead LLMOps practices focusing on performance monitoring, cost optimization, and model evaluation.
• Work with AWS Services: Hands-on usage of AWS Bedrock, SageMaker, S3, Lambda, API Gateway, IAM, CloudWatch, and serverless computing to deploy and manage scalable AI solutions.
• Contribute to Use Cases: Develop AI-driven solutions like AI copilots, enterprise search engines, summarizers, and intelligent function-calling systems.
• Cross-functional Collaboration: Work closely with product, data, and DevOps teams to deliver scalable and secure AI products.

• 5+ years of experience in AI/ML roles, focusing on LLM agent development, data, science workflows, and system deployment.
• A Bachelor's degree in Computer Science, Software Engineering, or a related field
• Demonstrated experience in designing domain-specific AI systems and integrating structured/unstructured data into AI models.
• Proficiency in designing scalable solutions using LangChain and vector databases.
• Deep knowledge of LLMs and foundational models (GPT-4, Claude, Mistral, LLaMA, Gemini).
• Strong expertise in Prompt Engineering, Chain-of-Thought reasoning, and Fine-Tuning methods.
• Proven experience building RAG pipelines and working with modern vector stores (FAISS, Pinecone, Weaviate, Qdrant).
• Hands-on proficiency in LangChain, LlamaIndex, Haystack, and DSPy frameworks.
• Model deployment skills using HuggingFace, vLLM, Ollama, and handling LoRA/QLoRA, PEFT, GGUF models.
• Practical experience with AWS serverless services: Lambda, S3, API Gateway, IAM, CloudWatch.
• Strong coding ability in Python or similar programming languages.
• Experience with MLOps/LLMOps for monitoring, evaluation, and cost management.
• Familiarity with security standards: guardrails, PII protection, secure API interactions.
• Use Case Delivery Experience: Proven record of delivering AI Copilots, Summarization engines, or Enterprise GenAI applications.
