He’s not Clueless Joe when it comes to the Mets.

Joe Girardi began asking friends and former colleagues about the organization in recent weeks, according to an industry source, well aware a managerial change could be coming. A vacancy was created with Mickey Callaway’s firing on Thursday, leaving the Mets among seven teams searching for a new manager.

The former Yankees manager is perhaps the biggest name on general manager Brodie Van Wagenen’s list of potential candidates for the job. Girardi’s résumé isn’t in question — he guided the Yankees to their last World Series title in 2009 and enjoyed 10 straight winning seasons in The Bronx — but the former catcher also departed the job amid questions of whether he could coexist with the front office.

A well-respected tactician, Girardi might have to convince Van Wagenen and Mets COO Jeff Wilpon he’s flexible enough to collaborate with the front office, while at the same time emphasizing that he’s nobody’s pushover.

“Joe doesn’t have to work, but Joe wants to work,” a former colleague of Girardi’s told The Post on Friday. “But he’s not just going to take anything, he wants to go where it’s the right fit for him. Is that the Mets? I don’t think he will know unless he interviews with them.

“He’s got to be able to mesh with the front office. I am sure Joe is going to say, ‘If I take this job it has to be this way.’ ”

Buck Showalter, Joe Maddon and Dusty Baker are other marquee names the Mets could potentially interview. Internally, quality control coach Luis Rojas is well-respected, and names such as Joe McEwing, Joey Cora and Joe Espada all have ties to the front office and await their first big league managing jobs.

“It’s an honor to be considered for a job,” Showalter told The Post’s Joel Sherman. “There’s a lot of quality people out there. We’ll see where it takes us.”

Girardi, who is working the ALDS between the Astros and Rays for Fox, will interview for the Cubs’ opening next week, according to multiple reports. Other managerial vacancies exist with the Giants, Padres, Pirates, Royals and Angels, but Girardi hasn’t been linked to any of those openings.

Girardi has studied the Mets, according to the former colleague, and sees a team capable of contending for the postseason, albeit with questions about the bullpen and outfield defense, in particular. The former colleague took exception to the notion Girardi is “tightly wound” — a description that has followed the manager throughout his career.

“Joe is passionate and he’s competitive and he’s going to do what he believes needs to be done,” the former colleague said. “I know one thing: There will never be an issue in the clubhouse, in the dugout with the accountability and that is what this game is losing now. You are losing accountability. Guys need to be told the truth. They don’t need to be told how great they are all the time.

“They need to be challenged — in the right way, not in a derogatory way — and that is what [Girardi] will do. He has the players’ backs, but if there is an issue he addresses it. I don’t think Joe is wound too tight.”
