Former Transport Minister Lui Tuck Yew has been appointed an independent director at Chip Eng Seng Corporation.
The construction and property firm told the Singapore Exchange that it would arrange for Mr Lui to receive relevant training to familiarise himself with the role and responsibilities of a director.
Mr Lui, 54, shocked observers when he resigned last August before the general election was called. He told Chinese daily Lianhe Zaobao then that his decision was a personal choice and had nothing to do with family or health reasons.
Mr Lui, who was formerly the chief executive of the Housing Board, entered politics in 2006, and rose quickly to become a Cabinet minister in 2010.
He was the Minister for Information, Communications and the Arts before taking on the role of Transport Minister in 2011. He later held a second portfolio as Second Defence Minister.
Prior to his political career, he had been chief executive officer of the Maritime and Port Authority of Singapore. He was a Singapore Armed Forces scholarship holder and the former Chief of Navy.
