The market right now
Alion currently lists 298 open Data Scientist jobs in London from 167 companies. 35 of them were posted or refreshed in the last seven days. 145 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary.
What these roles pay
47 of these Data Scientist jobs in London state pay directly. Across them the middle half of the market sits between $108K and $172K a year, with a median of $158K. By level, the median runs senior at $135K and lead at $172K. The step from senior to lead is worth about 1.3x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable.
Where the work is
The largest concentrations of these roles are United Kingdom (7), Sweden (6), Poland (3), Germany (3), and Netherlands (2). 27% of the listings are fully remote and a further 24% are hybrid, so a large part of this market is open to you regardless of where you live.

Each company page on Alion carries its size, funding stage, tech stack and every other position it has open, so you can judge the employer before you spend an evening on the application.
What employers ask for
Reading across the current listings, the tools that come up most often are Python (246), SQL (166), AWS (86), Spark (72), Azure (63), CI/CD (63), Databricks (60), and ETL/ELT (56). The counts are how many of these openings name each one, which is a better guide to what is actually being hired for than a generic skills list.
Relocation, visas and equity
Of the current Data Scientist jobs in London, 15 state visa sponsorship, 12 offer a relocation package, and 31 include equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you.
