Job postings on e-recruitment platform IrishJobs.ie were up 34% in the first quarter of the year, compared to the final quarter of 2020.
The data suggests the Irish jobs market is steadily recovering from the impact of the Covid-19 pandemic.
Overall, vacancies increased by 5%, when compared to the same period last year.
The most resilient sectors include pharmaceuticals, healthcare, and IT. Hospitality and retail remain among the most subdued industries.
The construction sector also experienced significant levels of growth in the first three months of the year, where job listings within the sector grew by 45% compared to the previous quarter.
This growth comes as the Irish construction sector began a phased reopening last week, resulting in a 7% increase in job postings within the sector, when compared to 2020.
Regarding job vacancies by location, Ireland's main cities have proven to be particularly resilient in the face of the third imposition of Level 5 Covid-19 restrictions, with all experiencing a rise in vacancy numbers quarter-on-quarter - Dublin (+47%), Limerick (+45%), Waterford (+35%), Galway (+21%), Cork (+8%).
Looking to the year ahead, General Manager of IrishJobs.ie Orla Moran said the anticipated reopening of sectors such as hospitality and retail will play a significant role in the country's recovery.
"It gives us reason to believe that there will be continued growth within the employment market over the next 12-month period.
"However, this will be a challenging process and one that remains entirely dependent on the course of the vaccine roll-out and the evolution of the virus, which we know are highly changeable," she said.
