Executive search firm Odgers Berndtson will assist the FAI in the quest to find a new permanent CEO for Irish soccer's governing body.
Rea Walsh, Noel Mooney, Paul Cooke, and Gary Owens have filled the role in an interim capacity since John Delaney's lengthy rein came to an end last year.
After more than 14 years at the helm, Delaney was initially placed on gardening leave in April 2019, and all ties with the FAI were severed with his resignation as executive vice president in September.
Delaney, who earned a basic salary of €360,000, received a severance settlement of €462,000 when he departed, which included a pension payment.
It also emerged that the Waterford man would have been entitled to a €3m loyalty bonus if he had continued to work for the FAI until 2021, with the payments to be made over 10 years from next year.
Delaney's permanent successor is expected to receive a smaller remuneration package as the beleaguered FAI faces considerable financial woes.
With debts of €62m, the FAI was forced to turn to the Government, UEFA and Bank of Ireland earlier this year as a refinancing deal was put in place to save the organisation.
