About The Role 
 
We re seeking a Senior Machine Learning Engineer or Applied Scientist to help design and deploy machine learning models for a suite of AI-powered products across the travel and hospitality space. This includes use cases in cruise, rail, airline, hotel upgrades, and ancillary services. The goal is to create a centralized intelligence layer that personalizes offers, optimizes pricing, and supports product decisions across multiple business lines. 
 
This role is ideal for someone who enjoys building from the ground up. You ll work on a greenfield ML system starting with one product line, proving out success, and then scaling the solution across additional partners and verticals. 
 
What You Ll Do 
 


* Collaborate with product and engineering to define modeling strategies and success metrics.
* Architect and implement machine learning models that support real-time decision-making.
* Ingest contextual and behavioral data through APIs to power intelligent pricing and recommendation systems.
* Design and build scalable ML pipelines from training to deployment using Amazon SageMaker Studio.
* Address common ML challenges like sparse data, partial signals, and cold start problems.
* Customize and tune models based on partner-specific data and business logic.
* Ensure solutions are reusable, scalable, and support both B2B and B2C deployment models. 
 
 

Must-Have Qualifications 
 


* 5+ years of experience building and deploying ML models in production environments.
