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   Product Reliability Engineers (PREs) are responsible for the health, performance, and stability of the services that power services at Palantir. PREs take ownership over the entire end-to-end cycle of service reliability, from responding to outages to improving codebases and building lasting solutions.   You will tackle critical issues for key customers, introduce observability into complex systems, address tech debt in essential codebases, and inform strategic investments in core products. We are looking for engineers who enjoy deep-dive troubleshooting, feel strong ownership over the problems they encounter, and recognize the urgency of customer-facing outages.   PREs spend the majority of their time on forward-looking product work, including but not limited to, infrastructure migrations, product contributions to improve stability and observability, and codebase enhancements that increase resilience. During periodic on-call shifts, we respond to automated alerts, investigate issues reported by customers, and share technical expertise with adjacent product teams.   Whatever the technical issue or question about your service is, you'll play a central and critical role in resolving it, seeking not just a one-time fix, but a permanent solution. We provide new team members with an experienced mentor and a clear onboarding framework to set them up for success in the role.
