Description The Intelligent Foundations and Experiences (IFX) team is at the center of bringing our vision for AI at Capital One to life. We work hand-in-hand with our partners across the company to advance the state of the art in science and AI engineering, and we build and deploy proprietary solutions that are central to our business and deliver value to millions of customers.  Our AI models and platforms empower teams across Capital One to enhance their products with the transformative power of AI, in responsible and scalable ways for the highest leverage impact.

This team owns the infrastructure layer between applications and foundation models: model access, routing, reliability, security integration, observability, and cost management behind a single governed interface. Product teams build on the platform instead of integrating with model providers directly, which means the enterprise adopts new model capability once, centrally, rather than many times over. Sitting in the request path for every AI-powered application makes latency, reliability, and efficiency company-level outcomes rather than local ones. This team also owns a measurement and attribution layer that makes consumption legible to the optimization capabilities that act on it, including intelligent routing, caching, context optimization, and capacity planning. The objective is cost per unit of business outcome, not spend reduction in isolation. The architecture set now will determine the enterprise's cost curve and build velocity for years, and this role owns both those decisions and the teams that execute them.
