Responsibilities

In the XFI Team, we deeply appreciate DevOps culture, as we build the XFI services, and we run it. Our day to day involves improving XFI services scalability and reliability; researching security vulnerabilities and implementing security measures; and monitoring production environments to discover what is next for the team using product data.

Our research also includes ways to improve user experience when using our products Outlook clients (desktop and OWA) on both Windows and Mac platforms and to help hardening the Human Security Layer.

Our main challenge ahead is scaling, both vertically (size of individual tenants) and horizontally (number of total tenants). We will consider experience working with data and infrastructure at scale as a bonus. If you are not sure that you exactly fit all the above criteria, please do get in touch anyway. We are always willing to speak to great candidates even if you do not feel you meet every criteria listed!
