About the Project

Join an experienced engineering team delivering AI-powered solutions for a global enterprise. You'll work on challenging machine learning problems involving large-scale data, computer vision, document understanding, and advanced deep learning models, taking ownership of the complete model development lifecycle—from data validation to production-ready implementation.

This role is ideal for someone with a strong theoretical foundation who also enjoys building practical, production-grade ML solutions.

Responsibilities

• Design, develop, and validate machine learning and deep learning models from scratch.
• Own the complete modeling lifecycle, from data exploration and validation through deployment.
• Work with both structured and unstructured data, including documents, images, and other complex data types.
• Translate business challenges into effective machine learning solutions.
• Develop production-quality Python code for data processing pipelines and model implementation.
• Evaluate model performance and continuously improve solution quality.
• Collaborate closely with software engineers and cross-functional teams to deliver scalable AI solutions.
