Findlay, 31, was with Solbakken at FC Copenhagen and will split his time with Norway for the remainder of the season before taking the job fulltime.
Findlay was an analyst at Manchester City's academy for two years, then worked as an analyst for Manchester United's first team under David Moyes, Louis van Gaal and José Mourinho, before eventually being headhunted by Wolves, where he worked under manager Nuno Espírito Santo - becoming part of the club's most successful season ever.
"He is exceptional on his computer and a damn nice guy. He will be planted in a glass cage at Ullevaal. No matter what we ask for or call for, he can find it in no time," Solbakken told VG.
"And then he's a service person. He has the English gene and works 12-14 hours every day. He will not be indignant if he is told that a player needs some video clips at 10pm in the evening, if someone in the team gets a whim about it."
