Senior Detection & Response Engineer - Expel

All right, close your eyes. Good. Now, I want you to picture the following person. This person has a real passion for detection. This person eats their Wheaties, with a side of freshly toasted attacker dreams of living off the land or sky (ahem, cloud). As a defender, they think it’s cute that the attacker has the impression they can get by a layered defense by not dropping any binaries and just using PowerShell, WMI, VBScript or the new hotness … and get away with it.

Please keep your eyes closed, we aren’t done visualizing. Next imagine this person is fascinated by engineering discipline. This person wishes unit tests for detections were as simple as importing pytest. They have a deep appreciation for what a great engineer can do with a hard problem. But they’re also someone who loves to solve hard engineering problems themselves, usually at the intersection of detection and response automation to make their lives, and their co-workers lives, a little easier.

Finally, this person we’ve been picturing thrives by working with others. They might eat breakfast and destroy the dreams of attackers, but they genuinely love working together on a problem. They are someone who has worked on a team to investigate and respond to alerts generated by a variety of signals. They know that true scale comes from enabling others.

Now open your eyes. First, I hope your eyes are open and you’re not someone who just blindly does what they’re told. Besides, how else could you have caught all the significant bits? Did you end up picturing yourself?
