Square is hiring across various teams. More specifically I'm an engineer on the infosec team and if you are interested in any aspect of security (from hardware/low level stuff to backend infrastructure, writing secure web applications, Android/iOS, etc.) you should consider joining our team!
Feel free to ask me any questions (email in my profile).
