After he graduated with a law degree from the École des sciences politiques, he began his career as diplomat with the French Ministry for Foreign Affairs. He first served as embassy attaché in the minister's office in June 1910 before transferring to the French Embassy at London in March 1911. By the time of his 1919 wedding, he was counselor of the Embassy there, eventually spending a total of years seventeen years with the London Embassy and was said to have developed a "genuine fondness for Britain".
From until 1938, he served as the French Envoy to Greece. From 1936 to 1940, he served as the French Ambassador to Romania in Bucharest, succeeding André d'Ormesson.
In June 1940, he was among a caravan of automobiles fleeing to Spain, which included Empress Zita, her brother Prince Francisco and sister Princess Isabel, Charlotte, Grand Duchess of Luxembourg (who was married to the Empress's brother, Prince Felix), Elisabeth, Philippine and Eugène von Rothschild, and the Polish pianist Stanislas Niedzielski.

On 7 August 1919, Thierry was married to Baroness "Nadine" Charlotte Thérèse Jeanne Mathilde de Rothschild (1898–1958), the only daughter of Baron Henri de Rothschild. She continued her father's philanthropic works with the French Hospital, and, upon his 1947 death, inherited a number of his paintings, including by Jean Siméon Chardin. Her younger brother, Philippe de Rothschild, was the father of Philippine de Rothschild, who inherited the family's French winery Château Mouton Rothschild. Together, they were the parents of three children, including:
His wife Nadine died at Villa Sansovino, her home in Cannes, on 22 October 1958.
