Data Scientist

A Data Scientist often works on predictive modelling, complex data problems, advanced analytics, and ML or AI applications. The role may also involve experimentation and translating findings into decisions. This makes it a hybrid role that sits between analytics and technical modeling.

Data Analyst

A Data Analyst usually focuses on metrics, data interpretation, visualisation, and business insights. The work is often tied to reporting and decision support. This is the most business-facing of the three paths.

Machine Learning Engineer

A Machine Learning Engineer usually focuses on machine learning systems, technical implementation, and engineering-oriented tasks. The role often involves making models usable in production settings. That makes it the most technical and systems-heavy path of the three.

Which Skills Are Shared Across All Three Careers?

Even though the careers are different, they overlap in important ways. That is why a broad MAS in Data Science can be useful for multiple career directions.
