In How I Met Your Mother, what do we know about Barney's profession except the fact that he works for GNB? References to the show (eg. "in Season X Episode Y,") will be appreciated.
From the HIMYM Wiki:
Not much is known about Barney's career.
It is assumed that he is a high ranking member in the company.
He has said that he knows so much about the company's dirty secrets, he won't ever be fired, (Episode 4x20: Mosbius Designs), although he was almost fired in the start of 2010 because he was blamed for the failure of a big merging. (Episode 5x14: Perfect Week)
His job also entails firing potentially hostile employees (Episode 4x18: Old King Clancy)
It's hinted that his job may include illegal activities (Episode 3x14: The Bracket)

In the episode Unpause (9x15)
- Barney's job is revealed as PLEASE (Provide Legal Exculpation And Sign Everything)
which means that the company he was working for set him up as a fall guy, as
the task legally implicated Barney in all corporate mishaps and schemes.
(But Barney was well aware of that and it was part of his long term plan to get revenge on the boss of the company, who was the reason why his first girlfriend Shannon left him)
