Ng, who served as chief of Singapore's air force between 2006 and 2009, will be a member of SIA Engineering's audit committee and the technology advisory committee.
Ng Chee Khern, permanent secretary at the Ministry of Manpower, has taken up a second listed company board role in less than a month.
SIA Engineering says 59-year-old Ng has been named a non-executive, independent director. The appointment of Ng, a retired two-star major general, will take effect on Feb 1.
