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 The Privacy and Civil Liberties (PCL) Engineering team is a interdisciplinary team of software engineers, forward-deployed engineers, designers, lawyers, and policy experts. The first of its kind in the tech industry, Palantir’s PCL team was formed 15+ years ago as a rejection of the prevailing view that privacy protections must be sacrificed to national security interest. Today, the mission of the PCL team goes far beyond civil liberties protections, and our work challenges other false tradeoffs between operational effectiveness and the defining values of our society: Effective military operations should not be at odds with protecting civilians and upholding the Law of Armed Conflict. Deploying AI with scale and speed should never compromise safety, reliability, and governance. The PCL team builds software and forward deploys to ensure that our customers can pursue their hardest operational challenges while keeping ethical imperatives in plain sight. You can read more about the team on the Palantir blog here. As a PCL Engineer, you will be responsible for designing and developing full-stack software products for privacy, data protection, AI governance, and accountability in Palantir’s software platforms. You may build security and governance primitives in our platform, applications for auditors, user-facing workflows for AI governance, internal tools for data protection, or something new all-together to help our customers address their next set of challenges. In every case, the software that you build will directly help our customers both carry out their missions more effectively and better meet their legal and ethical obligations. As part of this role, y
