Teraco, Africa’s largest neutral data centre and interconnection hub provider, is officially recruiting a Graduate Data Scientist for their Gauteng operations. This is a high-level entry role within the infrastructure that powers the continent’s internet, offering a unique opportunity to work where “big data” actually lives.
At Teraco, you won’t just be analyzing spreadsheets; you will be building the intelligent systems that monitor and optimize massive data centre environments. This role bridges the gap between raw infrastructure and advanced predictive analytics.
The Role: The Triple-Threat Data Scientist
Teraco is looking for a graduate who can navigate three critical pillars of modern data science:
1. Data Engineering (The Foundation)
You will design and build the pipelines that move data from sensors and systems into analytical environments. This involves managing the “3 Vs” of Big Data: Volume (massive amounts), Velocity (real-time speed), and Variety (different formats).
2. Artificial Intelligence & MLOps (The Brain)
Beyond just building models, you will learn MLOps. This means managing the entire lifecycle—from feature selection and model training to deployment and continuous monitoring to ensure the AI stays accurate over time.
3. Business Intelligence (The Impact)
You will translate complex mathematical findings into actionable insights. This involves building high-level data visualizations that help executives make multi-million rand decisions about data centre operations.
Minimum Requirements
- Education: A Degree in Data Science, Statistics, Computer Science, or a related quantitative field.
- Technical Skills: * Coding: Strong proficiency in Python (preferred) or R.
- Databases: Solid experience with SQL for complex querying.
- Concepts: Practical understanding of machine learning algorithms and data engineering principles.
- Attributes: A problem-solving mindset and the ability to simplify complex technical concepts for non-technical stakeholders.
Interview Prep: Possible Questions
- “Teraco operates data centres. How can Data Science be used to improve a data centre’s efficiency?”
- Tip: “Predictive maintenance is key. We can use sensor data (temperature, power loads, humidity) to build models that predict when a cooling unit or generator might fail before it actually does, preventing costly downtime.”
- “Explain the concept of MLOps to someone who isn’t a coder.”
- Tip: “Think of an AI model like a high-performance car. Building the model is like building the engine. MLOps is the entire pit crew and garage—it’s the system that keeps the car fueled, changes the tires when they wear out (model drift), and ensures it’s always running at top speed in a real race.”
- “What is your preferred Python library for data manipulation and why?”
- Tip: “I primarily use Pandas for data structures and NumPy for numerical operations. For the engineering side, I’m interested in how these integrate with tools like PySpark to handle the high-volume ‘Big Data’ environments that Teraco manages.”
Career Advice for Teraco Applicants
- Understand the Environment: Teraco is an infrastructure company. Research PUE (Power Usage Effectiveness)—it is a critical metric in data centres that data scientists help optimize.
- Highlight “Big Data”: If you have worked with large datasets (e.g., millions of rows) in your university projects, emphasize how you managed the “Velocity” and “Volume.”
- Communication is Key: The ad explicitly mentions “Excellent communication skills.” Be prepared to explain your most complex project in a way that a business manager would understand.
- Portfolio: If you have a GitHub repository, ensure your Python code is clean, well-commented, and follows PEP 8 standards.
