He was promoted to the Rangers from Hartford on December 15, 2015 after recording 2 goals and 9 assists in 27 games for the Wolf Pack to start the 2015–16 season.[6] Injuries to various New York Rangers' defenseman increased Skjei's ice time, but he failed to score any points in the 7 regular season games he played for the team.

On December 11, 2016 Skjei scored his first NHL goal against the New Jersey Devils. On April 16, 2017 he scored his first career playoff goal against the Montreal Canadiens.

However, he and teammate Brendan Smith were benched during the final 2 minutes of regulation in place of Nick Holden and Marc Staal as the Rangers would go on to lose the game in overtime despite leading 5-3.[7] On June 21, 2017, Skjei was named to the NHL's 2017 All-Rookie team.
Returning for his sophomore 2017–18 season, the Rangers struggled as a team, announcing a team rebuild in February. Skjei would see his points total dip to 25, but also a significant increase in ice time following the trade of team captain Ryan McDonagh.
