Software Engineer III

Summary
You will be joining the Privacy Competition Team and working on the Cross Application Data Use workstream. The engineer will be working independently on a queue of privacy tasks that are populated by automated detectors. Your job will be to efficiently investigate each task, understand the potential privacy violation, understand the code, and determine if there is a data violation. If a violation is detected, part of your task may be to write code to mitigate the data violation or to reassign the task to the appropriate oncall for the team that owns the code.

Hack is a derivative of PHP that Meta utilizes, so having a solid understanding of advanced object-oriented features such as polymorphism and generics is needed.
