Software Engineer Backend Ruby on Rails (m/f/d)

You will be joining AccountS team, some details about the team and the work they have been upto:

The team exists to act upon and mitigate any security incidents on our platform in a swift manner, the idea with the team is to work on both fronts product and security. Make it harder for illicit actors to enter the platform and carry out their activities by keeping the gates of XING stronger. This means we build mechanisms to monitor for this suspicious activities(spike in fake user creations, irregular login activities etc.), enhance on security measures for existing features(captchas, rate limiting etc.) and make sure when we're opening new gates to enter XING(login/signup with google, apple and some other internal and external products) we do so by not only accounting for product but for security as well.

PS: The S in AccountS stands for security.

Some example work the team has been up-to in recent past and the challenges you can look forward to:
- Login/Registration with google, apple(web, mobile), onlyfy (our former B2B brand), with their security measures such as google cross account protection.
- Monitoring and alerting setup for security incidents.
- Uncovering vulnerabilities in our vendor(third-party) ways of user creation and fixing them.
- Enabling our platform to transfer and associate logged-out user activities with their logged-in counterpart.
- Working along with security team to mitigate active security attacks such as user-enumeration.
- Exposing our login and registration endpoints via/to our graphql layer.
 
This is just to list a few to give you an idea about the nature of work team is involved in, a mix of product and security, where our expertise and passion lies.
