He was a district judge on the 15th Judicial District of Colorado from 1949 to 1957.
On July 2, 1957, Arraj was nominated by President Dwight D. Eisenhower to a seat on the United States District Court for the District of Colorado vacated by Jean S. Breitenstein. Arraj was confirmed by the United States Senate on August 5, 1957, and received his commission on August 6, 1957.
