Mansfield served as an apothecary in the U.S. Navy on the USS Vulcan during the Spanish–American War. After working as a pharmacist, Mansfield was admitted to the Massachusetts Bar in 1902; he worked as an attorney.
In 1913, Mansfield was elected treasurer and receiver general of the Commonwealth of Massachusetts serving from 1914 to 1915. In 1914, he lost his bid for re-election to Charles L. Burrill. He was an unsuccessful candidate for Governor of Massachusetts in 1916 and 1917.
Mansfield ran for Mayor of Boston twice. He finished second to James Michael Curley in November 1929, then topped a field of six candidates in November 1933. He served as mayor from 1934 to 1938, and was not eligible to run for re-election, as Massachusetts law at the time did not allow the Mayor of Boston to serve consecutive terms.
