Job Summary

A World-Changing Company

Palantir builds the worlds 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 forecast supply chain disruptions locate missing children and more.

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 organizations 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 truly fast and responsive experience requires applications to also directly interact with each other through client-side frameworks running in the browser. Building these frameworks is uniquely challenging: every Palantir application plays a distinct role and has its own set of first-class UX concepts yet the frameworks need to integrate cleanly into all of them. Success requires both strong API design skills and a keen eye for user experience.

The frontend frameworks our team builds serve a variety of functions across Palantirs application ecosystem. Some frameworks integrate deeply with the Palantir Ontologya foundational layer that provides a schema for defining objects and relationships between them. These frameworks enable real-time data synchronization across applications: for example when a user selects an Ontology object on a map data plots in a different application instantly update to show that objects properties. Other frameworks operate independently of the Ontology: for example one framework allows applications to define custom behaviors that can be invoked by other applications or even by AI agents giving them the flexibility to expose arbitrary functionality across the platform.

Core Responsibilities

As a software engineer on this team youll work with these cross-application frameworks end-to-end from the low-level technical implementation to high-level UX decisions. Youll work extensively with core web APIsBroadcast Channels Service Workers Local Storageto enable real-time communication between applications. Additionally you will help develop an Electron application that extends and enhances these workflows through Electron-specific capabilities such as the IPC API. Along the way youll build relationships with teams across the company and develop a deep understanding of different codebases and their architectural patterns.

API design is central to the role: the interfaces you create need to be ergonomic and portable enough to slot into any application that adopts them while also being powerful enough to enable complex user interactions. Just as important is a strong sense and passion for UX: the interactions these frameworks enable should feel native and intuitive regardless of which applications a user has open. The ideal candidate is a well-rounded engineer who is excited by the creative challenge of designing new cross-app behaviors and has the technical know-how to codify these behaviors in an idiomatic and extensible way.
