The 27-year-old has announced his ski jumping career is over and is now working at the Dartmouth Hitchcock Medical Centre in Lebanon, New Hampshire.

The double Winter Olympian will be repairing broken or malfunctioning equipment in his role as a clinical engineer.

"I have moved on from the sport of ski jumping," Alexander posted in a statement on Facebook.

"There were a lot of things that lead to my decision but the simple fact was that I wasn't happy with the direction that I was moving in; the progress I had been working hard for wasn't happening.

"It was time for a change. 

"The work is challenging but so far I'm really enjoying it."

Alexander had been competing in the International Ski Federation (FIS) Ski Jumping World Cup since 2009, with his best result a 27th place finish in Willingen last year. 

During his career he achieved one podium result in the Continental Cup, as well as various top ten finishes in Grand Prix competitions.

At Vancouver 2010, Alexander managed 41st place in the normal hill individual event, and he then finished 34th in the same event at Sochi 2014. 

He also came 10th in the team event with his US colleagues in Sochi.
