Data Scientist
Znane również jako: Applied Scientist · Advanced Analytics Specialist
Develops statistical and learning models on business data, tests their reliability and translates outcomes into usable conclusions.
The data scientist frames a research question, chooses a method and substantiates how certain an outcome is before decisions rest on it. Unlike the machine learning engineer, the task largely ends with a demonstrably working model rather than keeping it running in production. Selection targets algorithms and programming language, while the real bottleneck is explainability: a model the client neither understands nor can check is either not used or used without anyone knowing the assumptions.
