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 talking to us! We do have open positions in other teams too.
Some of the things we build get open sourced, for example: <a href=", <a href=", <a href=", etc.
Feel free to ask me any questions (email in my profile).
