Black & White Engineering has officially launched in Dublin Ireland marking the completion of our first European acquisition and a new chapter in our global growth.
The rebrand follows the acquisition of Homan O’Brien in May 2025 and an integration period that has seen the Dublin team fully aligned into Black & White’s One Global Team model.
To celebrate this milestone, more than 200 clients and colleagues from across Ireland and Europe joined the Black & White global team and at a launch event on 18 September in The Crypt at Christchurch Cathedral, Dublin. The event brought together industry leaders, clients and partners to mark the occasion and look ahead to the future of engineering in Ireland and beyond.
Creating Opportunities in Ireland
The Dublin office is set to play a central role in Black & White’s European growth strategy, with plans to create 60 new high-tech engineering jobs over the next three years. This expansion builds on Homan O’Brien’s legacy of more than 65 years delivering engineering excellence across healthcare, education, laboratories, commercial, residential, industrial and mission-critical sectors.
Simon O’Brien, Country Director, Ireland, said:
“We’re currently 32 people in Dublin with plans to grow the team to around 90. That’s 60 new high-tech engineering jobs and a real investment in Irish talent and skills. For our clients, it means continuity and stability with the same level of service we’ve always provided, while giving us the scale and support of a global network.”
Steven Horn, Managing Director, Europe added:
“Creating 60 new high-tech engineering roles in Dublin is a major step in building our European capability. These jobs represent real opportunities for talented engineers in Ireland to work on projects that have both a local and international impact. Expanding the team in Dublin also strengthens our ability to support clients across Europe with the depth of expertise and resources they need.”
A Strategic Step in European Growth
The acquisition and expansion in Dublin reflects the importance of Ireland as both a hub for multinational clients and a centre of engineering expertise.
Mick Cairns, CEO and Founder of Black & White Engineering, said:
“Dublin is a strategic hub for many of our global clients and having a strong presence here means we can be closer to them while creating significant new opportunities for engineers in Ireland. This is an exciting step in our growth journey, and we’re delighted to invest in the future of the Irish engineering sector.”
Black & White now operates in more than 18 cities worldwide with a team of over 1,000 people, recognised for technical excellence, data centre expertise, and sustainable design solutions.
As Black & White Engineering in Ireland, the Dublin team is already delivering projects across Ireland and mainland Europe, strengthening our ability to support clients and creating new opportunities for engineers at every stage of their career.
