Processing and normalizing standardized product data from trading partners worldwide. Extracting structured data from unstructured content using LLMs Automatic classification of items and data at catalog scale Big data visualization and analytics pipelines Massively distributed systems that push the limits of scale and performance If you've ever wanted to work on problems where the answer doesn't exist yet and build it, this is that opportunity.
