The Medical Council's fitness to practise committee has found a 40-year-old doctor guilty on one count of professional misconduct.
It said Dr Said Zia's failure to disclose his suspension by the General Medical Council in Britain was a substantial breach of trust and a failure in the standard expected of a doctor.
The committee said he had also failed to engage with the Medical Council in dealing with the complaint, factual matters were not disputed by Dr Zia and he gave no evidence in mitigation.
A decision on sanction will be made at a later stage by the full Medical Council.
The committee commended the fact that details of his GMC suspension had been communicated by the Health Service Executive to Sligo General Hospital during the process to recruit a paediatric doctor.
The 40-year-old doctor with an address in Ballincollig in Cork, who was a registrar, had applied to work at the hospital in September 2008.
However, it was alleged that he failed to disclose that he was the subject of an investigation by the GMC at the time and that his registration in the UK was suspended.
Today's inquiry heard that in correspondence previously to the Medical Council, after an inquiry was set up, Dr Zia said the position of the Irish Medical Council was of "no value" to him and the inquiry could do what it wished to do.
The last contact with the Medical Council was in December 2010.
The inquiry heard that it appears Dr Zia has not worked in Ireland.
Dr Zia is a German citizen, who was born in Afghanistan.
His interim suspension in the UK in July 2008, pending investigation, related to his alleged deficient performance in the care of two children.
Louise Beirne, barrister for the Irish Medical Council's Chief Executive, told today's inquiry that Dr Zia qualified in Germany and had excelled as a student.
She said that in his application to Sligo General Hospital in September 2008, Dr Zia said there was nothing in his conduct, character or personal background to adversely affect his ability to take the post.
