The number of professional job vacancies in Ireland rose by 7% between March and April, according to the latest Morgan McKinley Employment Monitor.
The study also shows the number of professionals seeking new roles fell by 15% during the same period.
This reflects improving economic conditions and the country's falling unemployment rate, which has dropped to a nine-year low of 6.2%.
The employment monitor indicates the biggest gains in the professional jobs market are in the financial services and professional services sectors.
It attributes much of this growth to companies making Brexit contingency planning as well as getting ready for the introduction of the European Union's General Data Protection Regulation next year.
Demand for professional candidates in the IT sector remains particularly strong, while German and Nordic language skills are the most sought after.
The study notes businesses are increasingly prepared to recruit internally and cross-train where skills shortages are becoming difficult to source, as well as offering higher salaries and more attractive benefits packages.
Commenting on the results of its employment monitor, Director of Inward Investment at Morgan McKinley Ireland Trayc Keevans said: "The continuing improvement in economic circumstances is feeding into a buoyant professional services recruitment market.
"We are seeing a strong pipeline of interest from abroad as potential inward investment projects seek information and guidance on skills availability in Ireland.
"This is a mixture of standard FDI interest and Brexit related concern on the part of international companies.
"We are also seeing strong organic growth in the Irish professional jobs market where companies have a positive outlook and are resourcing their requirements accordingly."
