Want to be the NSA's civil libs chief?

The National Security Agency is seeking a civil liberties and privacy officer to help it keep tabs on the fields in its pursuit of national security.

If you land the job, no doubt the eyes of the world will be firmly fixed on your work in the wake of a string of allegations of widespread covert spying on individuals and governments around the world.

In the role you may need to decide such things as whether implementing a backdoor in cryptography protocols violates civil liberties, or whether such a move would still maintain security for those not under the cross-hairs of the agency.

According to the job posting listed on the NSA's website, you'll be the primary adviser to the agency's director, General Keith Alexander.

You will also ensure that "privacy is protected and civil liberties are maintained by all of NSA's missions, programs, policies and technologies”.

The hire would be based at NSA's US headquarters in Fort Meade and receive up to $US173,000 for the gig.

The position pulled the responsibilities of NSA's civil liberties and privacy protection programs under single guidance.
