This team powers search and recommendation experiences across Airbnb's platform. In this role, you will work on the front door of search, transforming what guests type, tap, or say into a precise understanding of their intent. Your work will span autocomplete and smart compose, query tagging, query expansion, and intent modeling across Stays, Experiences, and Services. You will develop machine learning systems that understand free-form, natural-language, and multimodal queries while helping improve retrieval, ranking, personalization, and the overall guest experience. ### Key Responsibilities * Work with large-scale structured and unstructured data to develop and continuously improve machine learning models for product, business, and operational use cases. * Build query understanding capabilities including autocomplete, smart compose, query tagging, sequence tagging, named entity recognition, query expansion, and query/user intent modeling. * Develop natural-language search experiences powered by modern NLP and large language models. * Build models that extract entities and location context, classify search intent, and anticipate guest needs. * Collaborate with software engineers, product managers, operations teams, and data scientists to identify opportunities for business impact. * Translate product and business requirements into machine learning solutions and help prioritize model development. * Make engineering decisions and quantify the impact of machine learning systems. * Develop, productionize, and operate machine learning models and pipelines at scale for both batch and real-time applications. * Leverage internal and third-party ML tools and infrastructure to create reusable, high-performing systems. * Improve model development velocity, serving latency, reliability, and ongoing model quality. * Contribute to projects involving smart compose and language generation, LLM-based sequence tagging, query and location expansion, intent classification, and user-intent sequence modeling. ## Related Videos - [DevOps for Machine Learning](https://www.wearedevelopers.com/videos/179-devops-for-machine-learning) - [A Brief History of Data Storage](https://www.wearedevelopers.com/videos/974-a-brief-history-of-data-storage) - [Photonic Computing: Programming a New Class of AI Accelerators (incl.
