Palantir builds the world's leading software for data-driven decisions & 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, & more.

Palantir's software forms the operating system for the militaries of the United States & her allies, driving outcomes & enhancing capabilities across the full spectrum of operations, intelligence, & support activities. Our defense applications are the tip of that spear, powerful tools used daily by thousands of soldiers, sailors, airmen, & marines to perform critical work at home & abroad from the Pentagon to the front lines. The engineers who build, maintain, & extend these applications are responsible for wielding the immense technical potential of Palantir's data modeling & AI platforms to create exquisite domain-specific workflows & interfaces that modernize, extend, & revolutionize the capabilities of the warfighter.

This is a front-end engineering role focused on marrying Palantir's Foundry & AIP platform technologies, application specific backend services, & modern web technologies with domain expertise. These teams are nimble & 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 & 3D rendering, Redux (in various flavors) for state management, Conjure for API management, & OSDK for interaction with the foundry platform. A rich ecosystem of in-house libraries & toolchains sit on top of that foundation to provide cross-app messaging, live data streaming, robust classification based access control, & a host of other specialized functions. Defense applications developers both consume & produce these re-usable tools as part of their core engineering role.

As an engineer on a defense application team you'll be responsible for owning, not just executing, user-facing feature additions or enhancements. Defense product teams are forward-leaning by nature, you can expect to spend time hands-on with customers & forward-deployed engineers to design solutions that not only meet the need but deliver value rapidly to support customers in ever-changing environments. The dynamic nature of the defense applications teams make for, on average, shorter project cycles with high ownership at the individual contributor level but demand flexibility, practicality, & responsibility.

The highly autonomous nature of teams means you will transition from mentee to mentor quickly as you build unique expertise in specific applications & features. Palantir's engineering culture puts a premium on everyone having the skills & willingness to teach & learn, regardless of tenure. The best Palantir engineers form strong convictions quickly (to avoid analysis paralysis when every day counts) but hold them weakly, always ready to revise their opinion & update their world view when new ideas or additional data points are presented.
