Senior Data Scientist

Description

We are looking for a Senior Data Scientist to join our classification team. A critical component to enabling cross-border is delivering seamless clearance through customs. This is also an incredibly challenging problem where Global-e has radically changed the industry by delivering the world's first machine learning-based, highly accurate classification system that replaces the need for people to inspect and classify individual products. This capability enables our clients to ship goods from anywhere in the world to anywhere in the world directly from their stores and fulfillment centers, keeping customers happy with fast and seamless delivery. 

Main Responsibilities: 

• Be a subject matter expert in a ML domain. 
• Research, design, maintain, and evolve the company's machine learning models to support the world’s fastest and most accurate classification system for cross-border trade.
