Business Development Manager – Off-Site Manufacturing (OSM) | Driving Modern Construction Methods | Construction & Engineering Specialist

Kilkenny, County Kilkenny, Ireland

About

I started my career as a metal fabricator and worked my way up through production and account management into business development, so I’ve seen the industry from the ground up. That hands-on experience has given me a strong understanding of how projects actually run — from drawings and fabrication right through to site and delivery — as well as the commercial side of building and maintaining customer relationships. In my current role with Hilti, I’m focused on developing Off-Site Manufacturing (OSM) across Ireland, working with contractors and fabricators in sectors like pharma, data centres and energy. A big part of what I do is helping customers look at more efficient ways of building and supporting them with practical, engineered solutions. I’ve always enjoyed developing new business and building long-term relationships, and I’ve been fortunate to deliver strong growth in previous roles. I’m particularly interested in where construction is heading over the next number of years, especially around modern methods of construction, and being part of that shift.
