Anthony Weiner won't be out of work for long -- TMZ has learned "Hustler" kingpin Larry Flynt has personally reached out to Weiner to offer the former Congressman a "serious" job with his company.

Flynt fired off a letter to Weiner moments after the politician resigned from Congress earlier today saying, "After having learned of your sudden and compelled resignation from your Congressional post, I would like to make you an offer of employment at Flynt Management Group, LLC in our internet group."

Flynt insists, "This offer is not made in jest" and says he is "willing to pay twenty percent more than your former Congressional salary, ensuring that your medical benefits would be equal to what you were previously receiving."

Flynt -- an iconic figure in the free speech movement -- adds, "I feel that your unfortunate resignation is a prime example of unfounded political pressure and the hypocrisy that has invaded democracy in Washington D.C."
