Gomez was also a programme officer at the International Institute for Democracy and Electoral Assistance in Sweden, and a research and project manager for the Friedrich Naumann Foundation.

In between May 2009 to end May 2011 Gomez was the deputy associate dean (international) and head of public relations at the School of Humanities, Communications and Social Sciences at Monash University.

During 2015, Gomez co-founded the Asia Centre, an educational enterprise based in Bangkok that seeks to connect peoples and regions through collaborative partnerships.

He was a member of the Workers' Party team which attempted to contest the Aljunied Group Representation Constituency at the 2001 general election, but were disqualified because their nomination papers were incomplete.

The following day, the Elections Department confirmed that their closed-circuit television footage had revealed that Gomez had in fact put the form in his bag and left the building without submitting it.

PAP candidate Inderjit Singh speculated that Gomez's non-submission of the form may have been an intentional ploy to try to gain publicity and cause confusion.

On the eve of polling day, the Workers' Party leader, Low Thia Khiang, backed Gomez and stated that "the incident was merely an unintentional omission, a mistake made while busy".

On 8 May, two days after the election, Gomez was stopped by police at Changi Airport and prevented from boarding a flight to Stockholm (where he worked at the time for the International Institute for Democracy and Electoral Assistance).

However the public prosecutor stated that the willingness of Gomez to co-operate with the police and his lack of a previous criminal record led to the decision.

[15][16] Following this, former Prime Minister Lee Kuan Yew said that the decision not to prosecute did not make Gomez any less dishonest and called him a "bad egg".

His father, Thomas Vincent Gomez, was a founder and prominent member of the Singapore Manual and Mercantile Worker's Union (SMMWU).
