We are building AI-powered products and are looking for an exceptional AI/ML Engineer to join our core engineering team. You will design and implement production machine learning systems including LLM-based pipelines using LangChain and OpenAI, computer vision models using PyTorch, recommendation systems, and NLP applications. You will work on the full ML lifecycle from data collection and model training to evaluation, deployment, and monitoring in production. Our infrastructure runs on AWS with MLflow for experiment tracking and FastAPI for model serving. You will collaborate with product and data teams to identify AI opportunities, prototype solutions rapidly, and scale successful experiments to production. Experience with prompt engineering, RAG architectures, fine-tuning, and responsible AI practices is highly valued in this role.
