Position Overview

We are seeking an AI Algorithm Developer to design and implement machine learning algorithms for semiconductor manufacturing process optimization. This role requires a strong foundation in computer science fundamentals software engineering best practices and deep learning/optimization algorithms. You will work on challenging problems involving sparse noisy high-dimensional data from semiconductor equipment building models that predict on-wafer performance from recipe parameters.

The ideal candidate combines algorithmic depth (can reason through why not just implement) clean code practices (design patterns testing maintainable systems) and critical thinking (customizes algorithms to problem constraints rather than applying cookbook solutions).
