Full Stack Software Engineer - Application Development

About the Role

Palantir Foundry is an end-to-end platform for data-driven decision-making. As a Full Stack Engineer focused on application development in Foundry, you will be responsible for crafting the tools used by thousands of users to build sophisticated applications that power their businesses. You will architect and develop interfaces, state management, and access patterns to support data-intensive workflows that are both powerful and approachable.

You’ll regularly face sophisticated technical problems, requiring you to scope out solution designs and find incremental paths to ship new features. You will own APIs and schemas that power frontend code or collaborate with backend engineers to develop them together.
