He has previously played for the Atlanta Thrashers, Winnipeg Jets, Buffalo Sabres, Tampa Bay Lightning and Toronto Maple Leafs.

Nicknamed "Bogo", Bogosian was regarded as a complete, physical defenseman who could contribute on both offense and defense; he was rated as one of the top players heading into the 2008 NHL Entry Draft, where the Atlanta Thrashers selected him third overall.

[10] He was noted by his coach in Peterborough, Vince Malette, to be a "very physical defenseman who is a complete player" and defensively solid who could skate well with the puck and not lose speed.

Thrashers general manager Don Waddell liked the physical aspect Bogosian brought to a game, as well as his ability to help score goals while at the same time stop other teams' top players.

[14] He was named to the team's opening day lineup, and made his NHL debut in the first game of the season on October 10 against the Washington Capitals.

Twenty-four seconds into his first shift, Bogosian was called for a holding penalty,[15] while later in the contest, he had a fight with Capitals enforcer Donald Brashear.

After playing five games with the Wolves, including scoring his first professional goal on January 3, 2009, against the Rockford IceHogs, Bogosian rejoined the Thrashers for the remainder of the season.

[20] Though he did not miss any time from the injury, it had an effect on his offensive play; Bogosian was perceived to be more hesitant with the puck, choosing to pass it more often than shooting.

After he recovered, Bogosian admitted he did not play at his full capacity, but had decided not to disclose the injury to the team until the season finished in April 2010.

[22] The 10 goals he scored tied a team record for most by a defenseman in a season, first set by Yannick Tremblay in 1999–2000, the Thrashers' inaugural year.

[24] During the 2014–15 season, his seventh with the Thrashers/Jets franchise, Bogosian was traded alongside Evander Kane and the rights to Jason Kasdorf, to the Buffalo Sabres in exchange for Tyler Myers, Drew Stafford, Brendan Lemieux, Joel Armia, and a conditional first-round pick (Jack Roslovic) in the 2015 NHL Entry Draft.

[27] As a free agent, Bogosian drew league interest before signing a one-year, $1.3 million contract with the Tampa Bay Lightning on February 23, 2020.

[33][34] As a free agent from the Maple Leafs, Bogosian opted to return to the two time defending champion Tampa Bay Lightning in agreeing to a three-year, $2.55 million contract on July 28, 2021.

[38][39] During the 2009–10 season he was mentioned as a candidate to join the American team at the 2010 Winter Olympics in Vancouver, but a wrist and thumb injury led to a decrease in performance and he was ultimately not selected.

[44][45] In his senior season at Syracuse Ike was co-captain of the team with future New York Giants running back Joe Morris.

Aaron was also a professional ice hockey player who attended St. Lawrence University where he played four seasons with the Saints and served as team captain.
