Job Title: Mechanical Support Engineer (JuniorMid)
Location: Dublin, Ireland
Type: Contract (6-9 months initially)
Sector: Data Center Engineering / Mechanical Engineering

About the Role

Join Our Infrastructure Services as a junior-to-mid-level Mechanical Support Engineer and play a key part in supporting global data centre cooling and airflow modelling. Working within the mechanical engineering team, you'll collaborate with senior engineers. You will also work with stakeholders across design, construction, and sustainability. Together, you will enhance the efficiency and sustainability of global infrastructure.

Key Responsibilities

• CFD Analysis: Support computational fluid dynamics (CFD) analysis for airflow and cooling in data centres using tools such as HELYX, OpenFOAM, or similar.
• Simulation & Reporting: Post-process simulation results and prepare clear, visual summaries for senior engineering teams.
• Model Validation: Assist in validating CFD models against operational benchmarks and real world data.
• Collaboration: Work with design and sustainability teams to assess cooling performance and water usage impacts.
• Tool Development: Contribute to the development and improvement of in house airflow and water use modelling tools.
• Documentation: Help document simulation assumptions, inputs, and interpretations for internal knowledge sharing.
• Learning & Knowledge Sharing: Engage in specific training and participate in team knowledge sharing initiatives.
• Innovation Support: Occasionally assist with thermal/water modelling for experimental or emerging technologies.

Candidate Profile Basic Requirements

• Bachelors degree (or in final year) in Mechanical Engineering, Aerospace, or a related field.
• Strong grasp of fluid dynamics and heat transfer principles.
• Hands on experience with CFD tools (e.g., HELYX, OpenFOAM, ANSYS, SimScale, etc.).
• Basic Python scripting and data analysis in Excel.
• Excellent written and verbal communication skills.Eagerness to learn specific design standards and CFD workflows.

Preferred Experience

• 13 years experience in HVAC, data centre cooling, electronics cooling, or building services.
• Familiarity with psychometrics, airside economizers, or evaporative cooling systems.
• Experience scripting or automating CFD workflows (Python, bash, macros).Awareness of sustainability metrics (e.g., PUE, WUE).
• Passion for sustainable, scalable, high performance infrastructure.

Whats on Offer

• Opportunity to work on global, large-scale CFD projects in a leading edge environment.
• Flexible, part time hours with full access to resources, tools, and mentorship.
• Direct involvement in building and supporting world class infrastructure systems.
• Career development and learning opportunities in computational engineering and sustainability.
