Senior AI/ML Engineer (GEN AI) -Pune/Hyd

Job highlights

• 10+ years IT experience with 4-5+ years in NLP and Generative AI; expertise in intent detection, LangChain, LangGraph, AWS Bedrock, and ML frameworks
• Design, develop, and deploy intent classification and NLG models; architect LangChain/LangGraph applications; build scalable ML pipelines on AWS; lead experimentation and mentor juniors

We are seeking a highly experienced Senior AI/ML Engineer with deep expertise in Natural Language Processing (NLP), Generative AI, and cloud-native ML systems. This role is ideal for someone who has built production-ready intent detection models, NLG systems, and has strong experience with AWS Bedrock, LangChain, and LangGraph. Youll play a key role in architecting and scaling AI-first applications that leverage the latest in LLM, orchestration, and AWS-native services.
Key Responsibilities:

• Design, develop, and deploy intent classification and intent detection models using LLMs and traditional NLP methods.
• Build and optimize Natural Language Generation (NLG) pipelines for chatbot responses, summarization, content creation, or knowledge grounding.
• Architect and implement LangChain and LangGraph based applications for LLM-driven workflows (e.g., autonomous agents, RAG systems).
• Develop scalable machine learning pipelines using the AWS tech stack (e.g., Sagemaker, Lambda, Bedrock, Step Functions, DynamoDB, Athena).
• Integrate and fine-tune foundation models via AWS Bedrock, including Amazon Titan, Anthropic Claude, or Meta Llama.
• Collaborate closely with product managers, ML researchers, and backend engineers to translate business requirements into robust AI solutions.
• Lead experimentation efforts, conduct A/B testing, and ensure continuous evaluation of deployed ML models.
• Mentor junior ML engineers and contribute to best practices in MLOps, model governance, and responsible AI.
  Required Qualifications:
• Total 10+ in IT with 4 to 5 + years of experience in machine learning, with a focus on NLP and Generative AI.
• Strong experience building and deploying intent detection, text classification, sequence tagging, and entity recognition models.
• Proficient in LangChain, LangGraph, vector databases (e.g., FAISS, Pinecone), and orchestration of LLM workflows.
• Deep knowledge of AWS Bedrock, Amazon SageMaker, Lambda, DynamoDB, Step Functions, etc.
• Experience working with open-source LLMs (LLaMA, Mistral, Falcon) or commercial APIs (Claude, GPT-4, etc.).
• Proficient in Python, with a solid grasp of ML frameworks such as PyTorch, HuggingFace Transformers, scikit-learn.
• Strong understanding of MLOps practices including model versioning, CI/CD for ML, monitoring, and auto-scaling.
• Bachelor’s or Master’s in Computer Science, Data Science, or a related field.

Nice to Have:

• Experience integrating RAG (Retrieval-Augmented Generation) systems at scale.
• Familiarity with vector search using Amazon OpenSearch, Pinecone, or Weaviate.
• Experience with streaming data processing (e.g., AWS Kinesis, Kafka).
• Contributions to open-source AI/ML or NLP projects.
