Software Engineer - Core Interfaces

Join a Transformative OrganizationAt Palantir, we craft advanced software designed for data-centric decision-making and operations. Our platforms empower partners to create life-saving drugs, anticipate supply chain issues, locate missing individuals, and much more by connecting the right data to the right people.Position OverviewAs a Software Engineer focused on Core Interfaces, you'll be instrumental in developing applications that enable our clients to organize, analyze, and make informed decisions using their data. Our applications serve diverse roles within organizational workflows, leading users to operate multiple applications simultaneously with seamless integration. While backend services manage much of this coordination, creating a fast and responsive experience requires effective client-side frameworks that interact directly through the browser. This task is uniquely challenging; each Palantir application has distinct functionalities and user experience concepts, necessitating frameworks that integrate smoothly. Success in this role demands exceptional API design skills and a sharp eye for user experience.The frontend frameworks you will develop will support various functions across Palantir's application ecosystem. Some frameworks will integrate deeply with the Palantir Ontology, a foundational schema for defining objects and their relationships. These frameworks facilitate real-time data synchronization across applications; for instance, selecting an Ontology object on a map will instantaneously update related data in another application. Other frameworks will function independently of the Ontology, allowing applications to define custom behaviors triggered by other applications or AI agents, enhancing platform flexibility.Key ResponsibilitiesIn this role, you will oversee cross-application frameworks from technical implementation to high-level user experience decisions. You will extensively utilize core web APIs—Broadcast Channels, Service Workers, Local Storage—to enable real-time inter-application communication. Furthermore, you will contribute to the development of an Electron application, leveraging Electron-specific capabilities like the IPC API to enhance workflows. Throughout this journey, you will cultivate relationships across teams and gain deep insights into various codebases and architectural patterns.API design will be a central focus of your work; the interfaces you develop must be ergonomic and portable, easily integrating into any application that adopts them.
