About the position

We are looking for an enthusiastic, motivated and technologically curious individual with a Windows security focus to join Jane Street's IT Security team.

We’re looking for someone who fully enjoys working with and being around people, takes pleasure in triaging complex problems and is able to delegate and escalate tasks effectively. This role is anything but siloed; we’ll rely on you to be a key liaison between the IT Security team and other internal technology groups to distill and communicate pertinent information. While we’re open to individuals from a range of backgrounds, someone who’s worked in a code-driven environment and has hands-on experience with security incident response is preferred.
