JOIN THE GLANUA TEAM

What sets Glanua apart is the freedom and flexibility it offers. I have never felt confined to a specific role or department and have consistently been encouraged to progress my career within Glanua while simultaneously maintaining a positive work/life balance.

Robert Kearney, Contracts Manager

I joined Glanua through the CIF ‘Return with Confidence’ programme which was a brilliant opportunity to get back into the construction sector after taking time off to raise a family. It has given me a huge confidence boost and Glanua has been really accommodating and flexible to suit my current needs while also inspiring me to further my career in the company when the time is right for me.
