In 2003, Philbin joined the Green Bay Packers coaching staff. He spent nine years in Green Bay. During his tenure as offensive coordinator, the Packers offense ranked in the top 10 in the NFL for points scored and total yards every year, including their 2010 Super Bowl-winning season.
Miami Dolphins
In January 2012, Philbin was named the tenth head coach of the Miami Dolphins, beating out interim coach Todd Bowles and Denver Broncos offensive coordinator Mike McCoy, who were the other two finalists for the job. Philbin praised the Dolphins as a team with a "strong nucleus to build around," and the "passion" of the fans, players and management. Dolphins owner Stephen M. Ross stated that Philbin has all of the attributes that he was looking for in a head coach. Philbin guided the team to a 24–28 record during his time as the Dolphins head coach, unable to lead it to a winning record or make the playoffs. Through his first three seasons, the offense improved from a ranking of 27 to 11, but the defense slid from 7th to 20th. Philbin was fired by the Dolphins after a 1–3 start to the 2015 season. Reaction about the end of Philbin's tenure was met favorably by most fans and media alike. Tight ends coachDan Campbell replaced Philbin as the team's interim head coach.
Indianapolis Colts
Philbin was hired by the Colts as offensive line and assistant head coach ahead of the 2016 season. He replaced Hal Hunter, who was let go following the 2015 campaign.
Return to Packers
On January 10, 2018, Philbin was hired by the Green Bay Packers to once again serve as offensive coordinator, which he previously did from 2007 until 2011 when he was hired as the Dolphins head coach. On December 2, 2018, after a 17–20 Packers home loss to the 2–9 Arizona Cardinals, Philbin was named interim head coach of the Packers, after Mike McCarthy was fired. He was released at the conclusion of the 2018 season, along with most of McCarthy's staff.
On January 9, 2020, Philbin was hired by the Dallas Cowboys as their new offensive line coach. The move reunited Philbin with new Cowboys head coach Mike McCarthy, whom Philbin served as an assistant to with the Green Bay Packers from 2006 to 2012.
