A World-Changing Company Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, power decisions on the battlefield, locate missing children, and more. Applications for the Fall 2026 cohort are now open. The Program In the 20th century, America pioneered mass production. We built the Arsenal of Democracy, won the war, and then left the Arsenal to rust. Silicon Valley, a product of the Heartland, turned its back on the American worker. It’s time to reawaken the giant. The same spirit of practical innovation that enabled America to dominate the previous century lives on in every American factory, workshop, and garage today. The proliferation of Artificial Intelligence poses risks, but also the opportunity for a technological and industrial renaissance. Palantir is launching the American Tech Fellowship to arm Americans with the skills to deploy cutting-edge software in the workforce. Fellows will have an opportunity to explore and build on Palantir’s Artificial Intelligence Platform (AIP) and earn a professional certification in its use. Exceptional performers will earn an opportunity to interview for a role at Palantir or partner companies, where they can use their newfound skills to contribute to the reindustrialization and revival of America. This fellowship is about more than careers—it's about restoring the promise that hard work and determination can still change your life in America. It's an investment in American excellence, evidence of our belief that America's greatest builders are still to be discovered. The American worker, given the right tools and opportunity, remains our competitive advantage. It’s time to prove it. The Role In this fellowship, you'll participate in a comprehensive virtual training program with our partner, Ontologize, to level up your technical skills on Foundry and A
