Following trials with RSC Anderlecht, Tromso IL and Bodo/Glimt, Steiring opted to join Rosenborg BK ahead of the 2014 season. He made his senior debut in a friendly match in January 2014, but did not become a fixture in the first team.

In 2016, he again played the first two rounds of the Norwegian Football Cup. In the summer, he was loaned out to Viking FK, and made his Norwegian Premier League debut as a substitute in August 2016, against Rosenborg nonetheless.
