Scale, skills and the workforce behind Ireland’s engineering economy – a data-led analysis drawing on Eurostat, the Royal Academy of Engineering, and Higher Education Authority sources.
Engineering is not one of Ireland’s economic stories – it is the foundation beneath most of them. From pharmaceutical manufacturing and medical technology to digital infrastructure and energy systems, engineering skills are the common thread. Yet the workforce behind this economy is rarely examined as a whole. This article brings together validated data from three primary sources to set out what Ireland’s engineering workforce actually looks like in scale, composition, and pipeline.
Measuring engineering employment requires care about definitions. Two distinct frameworks are in use, and they produce very different headline numbers – both of which are valid, depending on what question is being asked.
The first is the occupational lens, used by Eurostat in its Labour Force Survey. This counts people employed in engineering and science occupations, using the ISCO classification system. It captures engineers regardless of which sector or firm they work in, but excludes non-engineering roles within engineering-led industries.
The second is the economic footprint lens, developed by the Royal Academy of Engineering in its Engineering Economy and Place study. This estimates the total employment supported by engineering-driven industries – including both direct engineering roles and supporting roles in operations, logistics, finance, administration and commercial functions that exist because of engineering activity.
This article reports both, drawing on Eurostat Labour Force Survey data, the Royal Academy of Engineering / Irish Academy of Engineering Engineering Economy and Place: Ireland report, and the Higher Education Authority’s graduate output statistics.
Eurostat’s Labour Force Survey provides the most consistent international benchmark. It measures employment in scientists and engineers occupations (ISCO-08 groups 21 and 31), which includes engineers across all sectors – manufacturing, construction, energy, information technology, and scientific research. On this measure:
Eurostat’s Labour Force Survey records approximately 343,000 people in scientist and engineer occupations in Ireland. In the same series, Ireland has one of the highest shares of employment in knowledge-intensive and science and technology occupations in the European Union – in 2024, the HRST-core group (tertiary-educated people in science and technology occupations) made up 31.9% of Ireland’s labour force, the fourth-highest share in the EU after Luxembourg, Sweden and Belgium.
Across the European Union as a whole, Eurostat records broadly similar headline magnitudes: in 2024, women alone accounted for around 7.9 million scientists and engineers in the EU, representing 40.5% of the total, which implies an EU-wide total of roughly 19.5 million. Ireland’s position within this EU total is small in absolute terms but distinctive in composition, particularly on the gender dimension explored below.

The Eurostat data highlight a distinctive feature of Ireland’s engineering workforce: Its relatively high female participation rate. In 2024, women accounted for 47.3% of scientists and engineers in Ireland, compared with 40.5% across the EU as a whole and 34.6% in Germany.
| Country | Women’s share | Context |
|---|---|---|
| Ireland | 47.3% | Top-quartile in EU |
| EU Average | 40.5% | Eurostat composite |
| Germany | 34.6% | Below EU average |

This places Ireland among the top-performing EU member states on gender participation in engineering-related professions. The structural reasons are not fully established in public data, but are likely linked to the sectoral composition of Irish engineering employment – heavier in pharmaceutical sciences and life sciences, which have historically attracted more women than civil or mechanical engineering, relative to the EU average.
Eurostat’s “scientists and engineers” category uses ISCO-08 major groups 21 (Science and engineering professionals) and 31 (Science and engineering associate professionals). This is a broad definition that includes physicists, chemists, geologists, architects and IT professionals alongside engineers in the conventional sense. Country-level figures should be compared with this scope in mind. The Irish figure reflects the high concentration of pharmaceutical, biotechnology and technology sector employment.
The Royal Academy of Engineering, in its Engineering Economy and Place: Ireland study (published 2025, drawing on 2022 Census data) conducted jointly with the Irish Academy of Engineering, applies a broader, place-based definition. Rather than counting only people in engineering occupations, it combines two lenses: engineers working in any industry, and all workers (engineer or not) employed within engineering businesses. The study estimates that Ireland has approximately 42,700 engineering businesses, representing 12% of the country’s total business base.
The RAEng / IAE study estimates that Ireland’s engineering economy employed around 725,000 people in 2022, equivalent to 31% of total employment. Of this total, 513,000 are in engineering occupations, of which 330,000 work in engineering businesses and 183,000 in non-engineering businesses. A further 212,000 non-engineers are employed within engineering businesses, giving 542,000 in total employed across engineering businesses of all kinds.
A notable finding is that approximately 40% of Ireland’s engineers work in companies outside traditional engineering sectors – for example, software engineers in financial services or process engineers in consumer goods. This points to engineering capability being diffused across the whole economy rather than concentrated in a narrow set of industries.

The study also finds that R&D intensity within the engineering economy is more than three times the national average: 22% of engineering-economy workers are in research, development or evaluation roles, compared with 7.5% across the workforce as a whole. R&D intensity is highest in the technology industry workforce (32%) and in manufacturing (18%). Engineering employment grew by 44% between 2011 and 2022, adding over 200,000 jobs, against 29% growth in total employment over the same period. Average earnings in the engineering economy were €59,300 in 2022, 14% above the national average, with occupations specifically titled “engineer” averaging €67,300.
Alongside its national findings, the study groups Ireland’s 31 administrative counties into five typology categories: Tech Heavyweight (the four Dublin counties), Engineering Powerhouse (five counties including Cork, Limerick, Kildare and Meath), Industrial Innovator (four counties including Galway and Waterford), Local Engine (eight counties across the Border and Midlands), and Embedded Engineering (ten counties, largely in the North-West and Midlands). Each category reflects a different combination of scale, value, local significance, industrial specialisation and R&D intensity.
Viewed across the island of Ireland, the figure is larger still. The President of the Irish Academy of Engineering, Sean Finlay, has noted that including Northern Ireland brings total engineering-economy employment to approximately one million people, or around 30% of the combined workforce on the island. This is a supplementary observation from Mr Finlay rather than a figure from the RAEng / IAE report itself, but it is useful context for understanding shared infrastructure, cross-border supply chains, and talent mobility across the labour market.
Engineering skills are deployed across a wide range of industries in Ireland’s economy. Drawing on the sectors listed in the RAEng / Irish Academy of Engineering study and the Eurostat occupational breakdown, several industries account for a disproportionate share of engineering employment and are closely linked to Ireland’s export performance and multinational investment base.
Pharmaceutical manufacturing is a dominant goods export sector for Ireland and a major employer of engineering talent. Engineering roles in this sector span chemical engineering, bioprocessing, quality systems, validation, and process automation. The sector is heavily dependent on the continued supply of qualified engineers, particularly as biologics manufacturing capacity expands.
The concentration of major global technology firms in Ireland – across software, hardware, semiconductors, and data infrastructure – has created demand for software engineers, systems architects, network engineers and data engineers that substantially exceeds what the domestic graduate pipeline can supply in many specialisations. This is reflected in the high share of non-Irish nationals in technology engineering roles.
Medical devices are a significant export sector for Ireland. The medtech cluster employs mechanical, materials, electronic and biomedical engineers, alongside a large quality and regulatory engineering function.
A large and growing domestic infrastructure programme – housing, transport, energy, water and utilities – competes for engineering talent with export-oriented manufacturing. Civil, structural and environmental engineers are in particular demand. This sector is predominantly Irish-owned, which means its engineering employment is structurally different from the export-led sectors: More distributed regionally, more exposed to domestic economic cycles, and more dependent on public procurement capacity.
Offshore wind, grid infrastructure, hydrogen systems, and the engineering required for large-scale data-centre power supply represent an emerging and rapidly growing demand for engineering skills – particularly electrical, mechanical and environmental engineering. This sector is likely to become a more significant engineering employer over the remainder of the decade.
| Sector | Primary engineering disciplines | Export linkage |
|---|---|---|
| Pharmaceuticals & biotech | Chemical, process, biomedical, validation | Very high |
| Technology & digital infrastructure | Software, systems, network, data | Very high |
| Medical technology | Mechanical, materials, electronic, biomedical | Very high |
| Manufacturing & industrial production | Mechanical, automation, process, quality | High |
| Construction & infrastructure | Civil, structural, environmental | Domestic |
| Energy & utilities | Electrical, mechanical, environmental | Mixed |
| Aerospace & advanced materials | Aerospace, materials science, manufacturing | High |
Ireland’s higher education system plays a central role in supplying engineering talent to a demand base that extends well beyond the domestic economy. Data from the Higher Education Authority (HEA) provides the key pipeline metrics, reported at the ISCED broad field level of Engineering, Manufacturing and Construction – a category wider than engineering alone but closely tracked.
In the HEA’s Class of 2024, Engineering, Manufacturing and Construction was the third-largest broad field of study, accounting for 11.3% of the 89,010 graduates from HEA-funded institutions – approximately 10,060 graduates in a single year. Total higher-education enrolment in 2024/25 stood at 278,880 across all fields. These graduates supply sectors including advanced manufacturing, pharmaceuticals, medical technology, energy systems, digital infrastructure, and construction.

Engineering, Manufacturing and Construction is also strongly gendered: It was the second-largest broad field for male graduates in 2024 (19.1% of all male graduates), but a much smaller share of female graduates. New entrants to higher education preferentially choose Business, Administration and Law, followed by Arts and Humanities, Health and Welfare, and then Engineering, Manufacturing and Construction.
Engineering skills are not evenly distributed across economies or industries – they cluster in activities that generate disproportionate economic value. In the Irish context, this concentration is unusually pronounced. The sectors that drive goods exports, attract inward investment, and generate the tax revenue that funds public services are, without exception, engineering-intensive.
As global economies become more technology-intensive, the relationship between engineering capability and economic competitiveness strengthens rather than weakens. Ireland’s unusually high engineering workforce concentration is both an asset and a dependency: It supports exceptional export performance, but it also means that any sustained gap between engineering talent supply and demand carries significant macroeconomic risk.
This article draws on three primary sources, each with distinct methodological scope:
The three figures cited in this article – 343,000 (Eurostat scientists and engineers), 725,000 (RAEng engineering economy, 2022) and approximately 10,060 graduates in a single HEA cohort – are not directly comparable and should not be combined arithmetically. Each reflects a different scope and methodology. Together they provide complementary perspectives on the scale and importance of engineering in the Irish economy; individually they answer specific and distinct questions about the workforce.
Ireland’s engineering workforce is large relative to the size of the economy, exceptionally diverse in its sectoral deployment, and unusually high in its female participation rate by European standards. Eurostat’s Labour Force Survey records approximately 343,000 people in engineering and science occupations, and Ireland ranks among the top EU countries on broader science-and-technology employment shares. The RAEng / IAE study, using a broader place-based definition, puts total engineering economy employment at approximately 725,000 jobs in 2022 – around 31% of total employment.
The graduate pipeline is substantial: In the HEA Class of 2024, Engineering, Manufacturing and Construction accounted for 11.3% of all graduates (approximately 10,060 graduates) and was the third-largest broad field of study. However, effective domestic supply faces structural pressures: Graduate emigration, intense international competition for engineering talent, and a domestic infrastructure investment programme that competes with export-sector employers for the same skill sets.
As the energy transition, infrastructure deficit, and AI-driven productivity shift all accelerate, the question of whether Ireland can continue to supply and attract the engineering talent its economy requires is not a niche workforce planning issue – it is a first-order economic question.
