A Little About Us
When you impact millions of people every day, you become a large target for adversaries in all layers of the stack. Our job is to keep our users safe and make Yahoo one of the safest places on the Internet. 

We are the information security team at Yahoo, we are known as “The Paranoids”. 

Specifically, we are the Track, Search, and Rescue team, similar in purpose but not your typical Incident Response team.  

We perform rescue operations to bring hosts and networks back from security emergencies, we search large quantities of data for trends and tactics to identify what needs to be rescued, and we track intruders in our network using traditional, modern, and experimental techniques.

If you like being in a high-pressure, high-performing environment with people who use proven techniques in these disciplines and also explore and apply experimental ideas, we have an incredible team-oriented group of like-minded individuals for you to join.

Individual team members are focused into one of the three disciplines creating new techniques designed to enhance our abilities and be highly effective in an insane chaotic scale.  Team members also rotate into the other disciplines to understand the relationships between the disciplines and apply knowledge in both directions: from secondary disciplines into the part-time, and also bring concepts from the secondary disciplines into the primary.

Keywords (if you are searching for these terms, it’s likely this role will interest you): Incident Response, Data Analysis, Data Analytics, Incident Management, Forensics, Splunk, Hadoop, Spark, Machine Learning, Anomaly Detection, Behavioral Analytics, Blue Team, Defense, Intruder Detection, Intrusion Detection, Security Analyst, Threat Analysis, Threat Intelligence, APT
