He was a member of the National Guard from 1921 to 1924. His father, J.N.O. Thomson, was a jeweler and prominent citizen of Ellensburg.

Thomson began his career in 1930 as a transitman with Land Cruise of Kittitas County, Washington.

He was promoted to project manager for Western Idaho and Oregon; regional training officer; and soils surveyor for Washington, Oregon, and Idaho. He conducted surveys and investigations of soils, land use, and dam sites, and did geologic mapping and groundwater surveys in Alaska, Washington, Idaho, Oregon, and South Dakota.

In 1954, Thomson became a member of the first Washington State University-Pakistan Exchange Program and with two others established the Department of Geology and Mining at the University of the Punjab, Lahore, West Pakistan.

Returning to the United States in 1956, Thomson joined the U.S. Bureau of Land Management in Spokane, Washington, as a land examiner until 1964. In this capacity he engaged in state mineral exams, mineral resource surveys, mining claim validity determinations, and did geological reporting on the Colville Indian Reservation. In 1966, he was employed as a geologist for the BLM Boundary Dam Project in Pend Oreille County, Washington. He later became an independent consulting geologist on topics such as ground water geology and small mine examination in Alaska and the northwestern states. Over the course of his career he authored several magazine and newspaper articles related to geology.
