The Applied Safety team ensures that users abide by X’s Terms of Service by detecting and remediating violative content at scale. Using machine learning and other signals, we identify threats and build automated systems to remediate misconduct with proportionate and transparent responses. We aim to eliminate illegal and inauthentic behavior on X and protect users from harassment or unwanted sensitive content.

Produce scalable systems capable of handling thousands of events per second
Apply creative problem solving cross-functionally across the entire safety ecosystem, whether it’s through engineering, product, or operations
Code using primarily Scala; Map-Reduce frameworks such as Scalding; and scripting languages such as Python
Potential for technical leadership in payments risk/financial fraud, child safety, or abuse
