About the Job

This is an exciting opportunity for a CFD Engineer to join the Sustainability & Building Physics team in Dublin, working exclusively on Simstudio CFD projects.

Simstudio is a specialist CFD company based in Zoetermeer, the Netherlands, focusing on airflow, heat transfer, and smoke control studies for data centres, wind engineering, and fire safety. As part of the Ethos group, Simstudio collaborates closely with the Sustainability team in Dublin on international projects across Europe and the Middle East.

In this role, you will be an integral member of both teams — embedded in the Dublin office while working daily with the Simstudio CFD team in the Netherlands. Together, you will deliver advanced CFD simulations that inform the design and optimisation of high-performance, sustainable environments.

The position is hybrid, based in Ireland, with attendance at our Dublin office as determined by project needs.
