Company Overview
Teraco Data Environments Location: Isando, Gauteng Teraco is the heart of Africa’s internet. They house the servers for global giants like Google, Amazon, and Microsoft. Because servers generate massive amounts of heat, cooling (HVAC) is the most critical part of their infrastructure. A failure in cooling means the internet goes down.
Location: Isando, Kempton Park.
About the Job
As a Graduate Engineer, you will work on large-scale industrial cooling systems that must run 24/7/365. This isn’t just about office air conditioning; it’s about precision environmental control.
Key Responsibilities:
- System Design & Modeling: Using CAD (AutoCAD/SolidWorks) to design and modify cooling layouts.
- Thermal Management: Monitoring heat loads and airflow within “data halls” to prevent server overheating.
- Maintenance & Projects: Assisting with the installation of chillers, cooling towers, and CRAC (Computer Room Air Conditioning) units.
- Efficiency Analysis: Helping the team find ways to reduce energy consumption (Power Usage Effectiveness – PUE).
Career Advice: Why Data Centers?
- The “Cooling” Specialty: HVAC is often a small part of Mechanical Engineering degrees, but at Teraco, it is the main event. If you specialize here, you become highly valuable to any tech firm globally.
- Competitive Salary: At R20,000+ per month, this is a top-tier graduate salary, reflecting the high responsibility of the role.
- Professional Growth: Teraco is known for its world-class facilities. Use this 18-month contract to work toward your Pr.Eng (Professional Engineer) registration by documenting your design and site experience.
Possible Interview Questions
- Technical: “What is the difference between sensible heat and latent heat in the context of a data center environment?”
- Design: “How would you use CAD to optimize airflow to prevent ‘hot spots’ in a server room?”
- Problem Solving: “If a cooling unit fails, what are the first three things you would check to troubleshoot the system?”
- Innovation: “Data centers use a lot of power. What are some modern HVAC trends that could help a facility become more energy-efficient?”
Quick Requirements Checklist
- Education: BEng or BSc in Mechanical Engineering (Focus on Thermodynamics/HVAC is a major plus).
- Software: Proficiency in AutoCAD or SolidWorks.
- Attributes: A “zero-failure” mindset—accuracy is everything in a data center.
