Software Engineer - Core Interfaces

The Role

Palantir builds applications that help customers organize, understand, and make decisions based on their data. Because these applications serve different roles within an organization's workflow, users frequently have multiple applications open at once and expect them to work together seamlessly. While backend services handle much of this coordination, delivering a fast and responsive experience requires applications to interact directly with each other through client-side frameworks running in the browser.

The frontend frameworks built by this team serve a variety of functions across Palantir's application ecosystem, including deep integration with the Palantir Ontology for real-time data synchronization, as well as enabling applications to expose custom behaviors that can be invoked by other applications or AI agents.

Core Responsibilities

• Work with cross-application frameworks end-to-end, from low-level technical implementation to high-level UX decisions.
• Work extensively with core web APIs (Broadcast Channels, Service Workers, Local Storage) to enable real-time communication between applications.
• Help develop an Electron application that extends and enhances workflows through Electron-specific capabilities, such as the IPC API.
• Design ergonomic, portable, and powerful APIs that integrate cleanly into diverse application codebases.
• Partner with teams across the company and navigate different architectural patterns.
