Come join a growing security team that is driven to design and improve platform security through innovation, automation, and excellence.

In order to support such obligations, yet not impede engineering progress, Security Engineers are charged with making security scalable, usable, continuous and native as well as being first-responders to potential security incidents. If finding security vulnerabilities and engineering solutions for them sounds like a day of fun, then this is the role for you.
