Data Scientist hiring in London: what the data shows
Compared with most AI hiring, this market is relatively open to earlier-career candidates — 74% of listings are mid-level or below, including 13% explicitly junior.
Demand is spread broadly across 21 employers rather than dominated by one — NRF, WTW, Hackajob are the most active this week, but no single company holds more than 9% of the roles.
Among the 10 cities HireIndex tracks for data scientists, London is the largest market by open-role count, making it one of the strongest hubs for this skill we track.
