ACT Brumbies great Joe Roff has emerged as a leading candidate to replace chief executive Andrew Fagan, who sensationally quit his Super Rugby job on Friday just months after signing a new one-year contract.

Fagan will leave the Brumbies next month after more than a decade at the club, including the past eight as chief executive.

The Brumbies will start their search to replace Fagan in the coming weeks and former Wallabies and Canberra great Roff looms as the front-runner to be the successor.

Roff - the University of Canberra Union boss - is on the Brumbies board and is one of the club's greatest players.

''It's no secret I love the Brumbies, [chief executive] is a great role to drive the direction of the organisation,'' Roff said.

''At the moment I'm enjoying my role at UC and I'm committed, but the Brumbies is something I'd consider.

''It's not a job that turns over often. It's one of the best jobs in sports administration, there will be a significant amount of interest.

''It would be something I'd love to consider, not many people get a chance to work in an area they love.''

Fagan cited the desire for new challenges as one of the major reasons he decided to resign, despite the club making the Super Rugby final in August.

He did not want to discuss if personal reasons were involved.

Fagan is one of only three chief executives in Brumbies history, following on from Mark Sinderberry and Rob Clark.

Fagan has been linked with Brumbies rivals the NSW Waratahs or a cross-code switch to the NRL in Sydney, but said his priority was to ''take a holiday'' before finding a new job. ''This job takes no prisoners, it's been 12 years … it's time to walk away and it's sad, but it's the right decision for me and the right decision and timing for the Brumbies,'' Fagan said.

During Fagan's Brumbies tenure it's estimated he generated $75 million for the club in sponsorship.

Fagan also oversaw the arrival and departure of three head coaches - Laurie Fisher, Andy Friend and Jake White.

Brumbies chairman Sean Hammond said the board would not be rushed into finding a replacement.

''I'd imagine there will be a lot of applicants, we're not ruling anything out and we just want the best person for the job,'' Hammond said.

''It's not a complete shock, we have been discussing it. It's too early to discuss a timeline, we have to put a system in place.

''No timing is perfect … there is a change, but I feel we're in good shape.''
