How much does a Data Scientist earn in Poland?
Data Scientist pay in Poland depends on seniority (Junior, Regular, Senior, Lead), the technology stack and the form of employment. Up-to-date medians and pay ranges (employment contract and B2B) are available in the full Curioz report, updated monthly from real data.
Which technology pays best for a Data Scientist?
According to Curioz data, the highest median salaries for the Data Scientist role are reached with PyTorch. The full breakdown of rates by technology and seniority is available in the report.
Does a Data Scientist earn more on B2B or on an employment contract?
B2B (hourly) rates and employment-contract (monthly) salaries follow different tax and risk logic. Curioz shows both separately for each seniority level and technology.
