Hindley was born in Dulwich, London to Charles Hugh Hindley, a carpet salesman and his wife Mary. Clement received an education from Dulwich College before studying mechanical sciences at Trinity College, Cambridge from which he graduated with a Bachelor of Arts degree in 1896.

East Indian Railway
Hindley visited the United States and Canada in 1904 on behalf of the Institution of Civil Engineers, returning to India in 1905 as personal assistant to the chief engineer of the East Indian railway. He was put in charge of the technical section of the agent's office in 1906, responsible for checking all plans and estimates for engineering works, before becoming the manager for the Delhi district of the railway. He became the secretary of the company in 1914, deputy general manager in 1918 and the general manager in 1920.
Chief Commissioner of Railways
Hindley left the company in 1921 for a position as chairman of the commissioner for the Port of Calcutta before becoming the first Chief Commissioner of Railways for India the next year. This latter role made him the chief advisor to the Indian government on railways and he used this to institute a reform of the railway sector including the opening of the Railway Staff College, the reorganisation of the Railway Department and the bringing of the East Indian and Great Indian Peninsular railways into public ownership. He brought the railways back to an efficient state following the decline of investment during the First World War and constructed more than 4000 miles of new routes before his retirement in 1928. In recognition of his services to India he was knighted in the 1925 Birthday Honours and was appointed a Knight Commander of the Order of the Indian Empire in 1929. He was also made a commander of the BelgianOrder of Leopold.

Hindley was a keen member of the Institution of Civil Engineers and in 1935 was made chairman of the new research committee before serving as vice president of the institution for the 1938-9 session and as president for 1939-40.
War work
Following the outbreak of the Second World War Hindley's position as president of the ICE made him useful to the war effort and he was employed as a works advisor to the London civil defence region committee and as chairman of the Air Raid Precautions committee to limit damage to structures and enginineering works for the Home Office. In 1940 he appointed as chair of the committee to consider post war reconstruction for the Ministry of Works and Buildings.
