The Italian company Hacking Team has job openings for hackers, see here:
Hacker / Developer
Developers design new features, develop them and polish our software to perfection.
Hackers find out how to overcome the original design of objects, hack into them and uncover all their secrets.
You have to be both, and the more you know, the better.
We need a person with a strong technical background, able to deeply understand how devices and software work and to hack them.
At the same time, you should be confident with lean programming and know how to structure code to fit into an enterprise scale software.
We only accept candidates with an unstoppable will to learn!
Depending on the area of development preferred knowledge is: C++, Objective-C, some x86 or ARM Assembly, Ruby or Python, ActionScript or reversing skills.
Design Patterns and Agile Programming are a must.
Work location is Milan, Italy, and on site presence is a plus.
