GitHub.com’s rapid growth and broad attack surface make it an increasingly popular target for malicious hackers, spammers, and fraudsters. Hackers know that we protect the key intellectual property of a massive number of companies and people. Spammers love the many vectors for delivering rich content through the platform: from creating spam on Gists, issue comments, and user profiles to even opening Pull Requests to add “ads” to repositories. Fraudsters seek to profit by abusing GitHub and third-party integrators for monetary gain. This large and varied attack surface gives GitHub a somewhat unique set of problems to solve.

The mission of the Platform Health team is to protect the health, safety, and integrity of the GitHub platform – establishing and preserving trust for the users, communities, integrators, and businesses that rely on GitHub. As a member of GitHub’s Platform Health team you will help develop tools and countermeasures to detect and prevent abuse on GitHub, build integrations between internal and external services, and advise product teams on best practices for making their products more resilient to abuse.
