Senior Data Scientist

Apify is built in Prague, but clients come from around the world - mostly the US. From nonprofits and Y Combinator startups to Fortune 500 companies like Microsoft and Samsung, plus government projects for the EU. We help clients improve their products, marketing, and business decisions using structured web data and automating repetitive tasks.
