Data Science
Data Engineer
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.
