What European tech jobs actually require
Every listing we ingest is read by a classifier that separates the skills a role requires from the ones it merely mentions. These pages report what that found — measured, not surveyed, and recomputed every six hours as the corpus moves.
Across 5,599 classified roles right now, the most requested skill is Python at 37% of listings.

Required, not mentioned
A listing that says “nice to have: Kubernetes” is not counted as requiring it. The split comes from the classifier that reads each advert, which is why these shares are lower — and more useful — than a keyword count would be.
Where we stay silent
Below 40 classified listings a role family shows no percentages at all. A share computed from eleven adverts is a number anyone can discredit, and every page here prints its sample size next to its claims for the same reason.
