The former director of information services may be in line for a highly paid post after her secondment to Tung Chee-hwa's office ends at the handover.
Irene Yau Lee Che-yun is understood to have been offered a number of jobs including general manager of corporate affairs at the Kowloon-Canton Railway Corporation (KCRC).
The post, which carries a salary package worth between $2.5 million and $3 million a year, became vacant when Barry Choi Ku-keung decided to emigrate to New Zealand.
Mrs Yau, 54, would have received about $2.4 million in salary and housing benefit at the Government Information Services, where she was director for 10 years.
If she decides to accept the offer, she would be the third senior official to join the KCRC recently.
The former secretary for transport, Yeung Kai-yin, 56, joined as chairman at the end of last year with annual remuneration estimated at about $5.5 million, twice the value of his package as a policy secretary.
The former secretary for works, James Blake, 63, joined this year in a newly created post as senior director (capital projects).
