Data Scientist II

In this role, you will design and build ML, NLP, and generative AI solutions to accelerate scientific discovery and knowledge extraction. You’ll work with large-scale, heterogeneous scientific content and collaborate across engineering, product, UX, analytics, and domain experts to deliver production-ready systems. You will translate ambiguous research challenges into measurable, data-driven outcomes that improve how researchers find and use knowledge. This position offers the chance to shape AI-enabled discovery at a trusted, collaborative organization with a focus on quality and impact.
