Remote Sr. MLE Engineer (AWS)

This global hotel company is looking for very skilled Machine Learning Engineers. Design and build end-to-end machine learning and AI systems that power customer-facing and internal business applications. Partner closely with Data Scientists, GenAI Engineers, and Product teams to bring AI solutions from concept to production. Architect scalable solutions across data, machine learning, cloud infrastructure, APIs, and application layers. Build, deploy, and manage production ML services, model-serving infrastructure, and real-time inference systems. Develop and maintain the infrastructure that supports recommendation engines, ranking systems, forecasting models, and agentic AI applications. Create and manage APIs, integrations, feature stores, data pipelines, and other critical ML platform components. Own solutions throughout their lifecycle, from design and implementation to monitoring, optimization, and ongoing support. Work across AWS, GCP, and distributed systems to ensure reliability, scalability, and performance of ML-powered applications. Troubleshoot complex production issues and optimize systems handling real-time traffic and business-critical workloads. Drive architectural decisions and help define how machine learning capabilities integrate with broader enterprise platforms and services.

The MLE team serves as the bridge between Data Science, GenAI, Agentic AI, and Platform Engineering teams. They are responsible for:

Designing end-to-end ML and AI systems Translating business and AI use cases into scalable architecture Building and maintaining ML infrastructure Integrating models into production environments Managing real-time applications and dependent services Supporting recommendation engines, ranking systems, and customer-facing applications Operating feature stores, model serving platforms, and other ML infrastructure components

For example, if a team is developing an agentic AI solution to improve hotel performance, the MLE team designs how the data, models, cloud infrastructure, APIs, and downstream systems work together to support that solution in production.
