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, forecast supply chain disruptions, locate missing children, and more. The Role Palantir’s software forms the operating system for the militaries of the United States and her allies, driving outcomes and enhancing capabilities across the full spectrum of operations, intelligence, and support activities. Our defense applications are the tip of that spear, powerful tools used daily by thousands of soldiers, sailors, airmen, and marines to perform critical work at home and abroad from the Pentagon to the front lines. The engineers who build, maintain, and extend these applications are responsible for wielding the immense technical potential of Palantir’s data modeling and AI platforms to create exquisite domain-specific workflows and interfaces that modernize, extend, and revolutionize the capabilities of the warfighter. This is a front-end engineering role focused on marrying Palantir’s Foundry and AIP platform technologies, application specific backend services, and modern web technologies with domain expertise. These teams are nimble and select the right tool for the task in front of them rather than adhering to a rigidly defined tech stack, but the most common setups are React for standard DOM rendering, Maplibre and/or Three js for geospatial and 3D rendering, Redux (in various flavors) for state management, Conjure for API management, and OSDK for interaction with the foundry platform. A rich ecosystem of in-house libraries and toolchains sit on top of that foundation to provide cross-app messaging, live data streaming, robust classification based access control, and a host of other specialized functions. Defense applications developers both consume and produce these re-usable tools as part of their core engineering role. Core R

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 Are you passionate about engineering quality, efficiency, and increasing the impact of engineers around you? Software Engineers at Palantir build software that transforms how the world’s most important organizations use data. As an engineer focused on Frontend Developer Productivity, you’ll work within our Frontend Infrastructure group to identify, develop, and drive investments to improve the velocity and quality of our engineering. Our frontend infrastructure group covers our entire frontend development stack, from the developer experience in the IDE to the final user experience in the browser. Across the group, we are responsible for developing and maintaining: • The build and CI system for a large frontend monorepo with millions of lines of code and hundreds of active developers. • Core infrastructure required to develop and serve our frontends, including feature flags, internationalization, and commit previews. • A GraphQL API for declarative data loading, spanning many underlying services. • Blueprint, the open source UI framework used by all of Palantir's applications and thousands of developers around the world. • A variety of tools and VSCode extensions that improve developer experience across the company. With an ambitious roadmap ahead of us, you'll have the opportunity to make a lasting difference on application development at Palantir.

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, forecast supply chain disruptions, locate missing children, and more. The Role Apollo is Palantir’s autonomous software management and deployment platform. It enables seamless, continuous delivery of mission-critical software (Foundry, Gotham, AIP) across a vast range of environments: on-prem, public cloud, disconnected (air-gapped) networks, and highly regulated settings (including IL-5 and FedRAMP). As a Software Engineer on the Apollo team, you’ll build and operate a large-scale distributed system to allow the remote operation and maintenance of Kubernetes clusters. Our mission is to extract the entire state of a cluster into a portable, high-performance artifact within minutes, enabling full and almost instant cluster reconstruction from the ground up—all while pushing the limits of speed, reliability, and scale. You’ll design and implement backup and restore solutions for Kubernetes, leveraging proprietary compression infrastructure tailored to Palantir’s unique deployment models. You’ll also build and optimize our container artifact store, which is based on the OCI (Open Container Initiative) distribution spec—the industry standard for storing and distributing container images and artifacts. You’ll own the backbone of every environment Apollo supports, from hyperscalers to Army trucks. If you’re excited by challenges at the intersection of container technologies like OCI and docker, storage, and distributed systems, you’ll find opportunities here to dive deep into storage formats and low-level optimizations, where milliseconds matter. As we increasingly automate cluster creation and management on diverse hardware, you’ll play a key role in scaling Palantir’s presence at the edge and solving tough distributed systems proble
