The map
IT careers are a graph, not a ladder.
Every role on this site, joined by the moves people genuinely make between them. There is no top and no bottom — just a lot of doors, most of which lead to more doors. The circles with a second ring are the 10 you can reach with no experience at all.
Open a role to see what it pays to start, what it leads to and why, then ask the map for a route: pick where you are now and where you want to end up, and it shows the moves between them in the direction people actually make them. The layout is computed from the connections themselves, so roles that share a lot of ground end up near each other — which is why the fields form clumps without anyone drawing boundaries around them.
Don't know where you'd start?
A map is only useful once you know roughly where you are. The scenarios show you the problems rather than describing them, and tell you which ones you keep reaching for.
Two of these look the same?
Neighbouring circles are often near-identical jobs with different titles. The comparisons put any two of them side by side on the same dimensions.
