Moore is understood to have already left the company while Fawcett is set to leave at the end of the month.
According to a source close to the situation, Fawcett is in discussions to move to a similar brand led role at a new company, but is "is open to approach, but is weighing up options from several interested parties."
He was recently involved in the Sony Ericsson sponsorship of the UEFA Champions League. It is not clear if Moore is involved in broaching similar opportunities.
A further senior member of the Sony Europe Giles Morrison, pan-European brand director at Sony is also believed to be in consultation regarding his role.
Moore joined Sony in 2007 and prior to that was head of marketing communications at global sportswear manufacturer Nike. He is also a former head of account management at creative agency Lowe and Partners.
Fawcett was previously worldwide strategy director at PHD and prior to that was managing partner at Mindshare Worldwide, primarily working on the agency’s Nike account.
Morrison joined Sony in 2008 and was formerly business director at creative agency BBH London working on accounts including Unilever Oral Care and Diageo.
In April, Sony Europe admitted that its sales and marketing teams had entered consultation, but had not provided specific names or job titles at risk.
A Sony spokesperson confirmed at the time that the official 90-day consultation was likely to heavily impact on sales and marketing-related roles as Sony seeks to cut-out "duplication".
In the same month Sony was subject to scrutiny from investors when it announced a quarterly loss of almost £1bn. It bought Ericsson’s share of Sony Ericsson in October 2011 for £0.84bn taking control of the company.
A spokeswoman for Sony Europe said the electronics giant would not comment on the departures.
