Role description
T+S USC/GC onsite day 1 We are looking for a Senior AI/ML Engineer to design and scale next-generation AI applications leveraging Natural Language Processing (NLP), Generative AI, and AWS-native machine learning systems. This is a hands-on role where you’ll build production-ready models, architect LLM-driven workflows, and deliver real-world impact. What You’ll Do β€’ Design and deploy intent detection, classification, and entity recognition models. β€’ Build natural language generation (NLG) pipelines for chatbots, summarization, and content creation. β€’ Architect and implement LLM workflows using LangChain and LangGraph (agents, RAG systems, orchestration). β€’ Develop and scale machine learning pipelines on AWS (SageMaker, Lambda, Bedrock, Step Functions, DynamoDB). β€’ Fine-tune and integrate foundation models via AWS Bedrock (Claude, Titan, LLaMA, etc.). β€’ Partner with product, research, and engineering teams to translate business needs into AI-first solutions. β€’ Lead experimentation, A/B testing, and continuous model evaluation. β€’ Mentor junior ML engineers and contribute to MLOps, governance, and responsible AI best practices. What We’re Looking For β€’ 4+ years in AI/ML engineering with strong focus on NLP and Generative AI. β€’ Proven experience building production-ready intent detection, text classification, and NLG models. β€’ Hands-on with LangChain, LangGraph, vector databases (FAISS, Pinecone, Weaviate). β€’ Deep expertise in AWS ML stack (SageMaker, Bedrock, Lambda, Step Functions, DynamoDB). β€’ Proficiency in Python and ML frameworks (PyTorch, HuggingFace, scikit-learn). β€’ Strong MLOps knowledge: model versioning, CI/CD, monitoring, and scaling. β€’ Experience working with both open-source LLMs (LLaMA, Mistral, Falcon) and commercial APIs (Claude, GPT-4, Titan). Nice to Have β€’ Experience with RAG (Retrieval-Augmented Generation) at scale. β€’ Familiarity with Amazon OpenSearch, Pinecone, or Weaviate for vector search. β€’ Exposure to streaming data systems (AWS Kinesis, Kafka). β€’ Contributions to open-source AI/ML or NLP projects.
