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.

Responsibilities:

  • Carry out CFD simulations to assess airflow, thermal performance, wind conditions, smoke movement, and environmental comfort.
  • Work on advanced CFD projects for data centres, wind engineering, and fire safety applications.
  • Translate complex CFD outputs into clear, actionable recommendations for clients, architects, and engineering teams.
  • Collaborate closely with both Ethos and Simstudio engineers to integrate CFD findings into overall design strategies.
  • Prepare detailed technical reports, visualisations, and presentations for internal and external stakeholders.
  • Contribute to the development of modelling methodologies, QA/QC procedures, and R&D initiatives within the joint CFD team.

  • Experience using AutoCAD, Revit, and MS Office for supporting workflows.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
