Auth0 Sr. Engineer, IAM Continuous Authentication

What's the opportunity?

As we scale Auth0 and handle billions of logins per month, we also have to deal with billions of attacks. Almost 40% of our traffic are bots trying to get access to our customer's accounts and our job is to not let that happen.

At the same time we want to provide a great experience to our users and let them know when something suspicious is going on: someone logged in from a device that was not seen before; from a place that would be impossible based on previous activity; from a TOR node; etc.

Finding the right balance between security and user experience is a hard problem to solve. This is the mission of the Continuous Authentication team.
