The Microsoft Threat Intelligence Center (MSTIC) tracks nation state and criminal actors to protect Microsoft and Microsoft's customers. The actors we track are often highly technical, and maintain good operational security. Tracking actors like this requires persistence and ingenuity and is done by combining intelligence analysts, reverse engineers, developers and data scientists.

Some of the successful investigations that MSTIC has performed include discovering and disrupting supply chain attacks from North Korean actors, identifying attacks from Iranian actors against universities and research organisations, and monitoring new techniques deployed by Russian actors.

MSTIC also co-operate with the Digital Crimes Unit (DCU) to prevent cybercrime, particularly ransomware. Our team in Dublin is expanding and we're looking for individuals interested or experienced in threat intelligence, with good development experience, to help us scale up our nation state and cybercriminal actor tracking.

Your role would be to track actors, perform investigations and automate that hunting work through python development. (If you are familiar with using the Storm language and Azure Data Explorer, all the better).
