Most jobs (at least, the senior roles) are still concentrated in US (New York and Bay Area), but some places are catching up fast: Singapore, Spain, Ireland, and London. Below is a list of companies with the largest numbers of data scientists, based on Data Science Central internal data. The list is based on the author’s 10,000+ LinkedIn connections, broken down per company, and ordered by number of connections. Note that there are many ties outside the top 15. Only companies with at least 5 connections are listed here.The top 20 companies represent about 10% of all data scientists, but the distribution has a very long, unusually heavy tail."
