Originally a specialist in Nordic Combined, Alois Moser was selected for the national team of his native Austria at the age of 15, but never had an opportunity to compete at a major international tournament in this discipline. After World War II he moved to Canada with his family and soon took an interest in ski jumping, a sport that earned him a spot on the Canadian national squad in 1959. He competed at the Winter Olympics the following year, but finished 44th in a field of 45 competitors. His only other major international appearance came at the 1959-1960 Four Hills Tournament, where he was ranked 43rd overall. He retired from active competition shortly thereafter and eventually returned to Austria, where he spent the remainder of his life working as a dentist.
