Client is seeking a highly skilled Senior Machine Learning Engineer to join its Data Science & Analytics organization. This is a backend-focused machine learning engineering role centered around building and operationalizing scalable AI/ML systems in production environments.
This is not a pure research or data science position. The ideal candidate will have strong software engineering fundamentals and experience implementing machine learning-driven products and services at scale within cloud environments.
The engineer will work closely with Data Scientists, Data Engineers, and Architecture teams to productionize machine learning solutions powering personalization, recommendation systems, analytics platforms, chatbot interfaces, and operational intelligence applications across Hyatt s digital ecosystem.
The environment is highly dynamic and fast-paced, supporting approximately 20 active applications and services. Candidates must be comfortable operating in ambiguity, learning new concepts quickly, and independently driving solutions end-to-end.

What the Hiring Manager is Looking For
The hiring manager emphasized that foundational engineering strength, adaptability, and critical thinking are more important than exact tool matches.
Strong candidates will demonstrate:
- Exceptional software engineering and computer science fundamentals
- Experience building scalable backend systems supporting ML workloads
- Ability to architect, deploy, and maintain production-grade AI/ML services
- Comfort working in ambiguous and evolving environments
- Strong analytical and systematic problem-solving skills
- Fast learning ability and intellectual curiosity
- Experience collaborating cross-functionally with Data Scientists and Engineering teams
- Proven delivery experience in enterprise or high-scale technology environments
Candidates with pure data science or research-heavy backgrounds are less aligned unless they possess strong production engineering experience.
