Data Science

Data Scientist

Somewhere between a researcher and a software engineer sits the data scientist, the person who answers questions a company didn't quite know how to ask. The work blends statistics, programming, and a stubborn refusal to accept easy explanations.

One week you might design an experiment to measure whether a new feature actually causes more usage, the next you might build a forecasting model that shapes next year's hiring plan. Students who enjoyed both math class and writing essays tend to thrive.

Tools like Python and PyMC become daily companions, but the deeper skill is asking the right question. Excellence looks like a recommendation that holds up six months later because the underlying causal reasoning was sound.

Problem framing + experimental design + defending methodology to non-technical audiences are exactly the parts of the role AI augments but doesn't replace.

Data Science
Data Engineer
US$119,658
Every clever dashboard, every machine-learning model, every executive report rests on plumbing that someone built and maintains. Data engineers build that plumbing. They design the pipelines that move information from production systems into warehouses where analysts and scientists can use it, and they keep those pipelines reliable as data volumes grow. The role suits students who enjoy systems thinking and care about how things actually work under load. Days involve writing transformations in dbt, scheduling jobs in Airflow, and quietly catching bad data before it reaches a decision maker. Excellence shows as pipelines nobody notices because they never break. You grow into this by writing a lot of SQL, picking up Python, and learning one cloud platform deeply.
