Summary

At Hyatt, we're working to Advance Care through data-driven decisions and automation. This mission serves as the foundation for every decision as we create the future of travel. We can't do that without the best talent – talent that is innovative, curious, and driven to create exceptional experiences for our guests, customers, owners and colleagues.

Hyatt seeks an extraordinary Machine Learning Engineer to help build the algorithmic assets and features that Hyatt guests, members, customers and internal users leverage to transform the guest experience and drive efficiencies across the operations of our business.

In this role you will design and implement algorithmic product architectures across Personalization, Generative AI, Forecasting, and Decision Science domains, as well as foundational MLOps frameworks to bring our machine learning models to life across the full lifecycle of the product including data ingestion, ML processing, and results delivery/activation. This role combines deep technical modeling expertise with infrastructure engineering skills to design, build, and operate end-to-end ML/AI systems at scale. You'll work across the full ML lifecycle - from distributed training and model optimization to production deployment and monitoring.

This role will work cross-functionally with various data science teams, data engineering teams, and data architecture teams. The ideal candidate can serve as both solutions architect as well as hands-on implementation engineer and guide the team towards best-in-class MLOps platform and algorithmic product implementations.

You will be a part of a ground-floor, hands-on, highly visible team which is positioned for growth and is highly collaborative and passionate about machine learning and AI. Applying the latest techniques and approaches across the domains of data science, machine learning, and AI isn't just a nice to have, it's a must.
