Do you want to join one of the world’s most technologically advanced quantitative trading firms, where you’ll build security solutions protecting complex, high-performance systems operating at a global scale.
This is a hands-on engineering role for someone who can write high-quality software, understands how systems and infrastructure work, and wants to build tools and controls that protect a complex, large-scale technology environment.
We are not looking for a traditional cyber-security analyst, or someone focused primarily on penetration testing. The ideal candidate will have strong computer science fundamentals and approach security challenges as a software engineer.
