These are the engineers in the Zelcast network and the profiles run through the Eng Scorer, not Amazon Web Services (AWS)'s headcount: 1,035 people on a map of 26,572, the No. 6 company on it by people. Updated August 20, 2026. Amazon Web Services (AWS) sits inside Amazon. The map keeps the two apart because each hires under its own name, and marks every move between them rather than counting it as a change of employer.

Came from, went to
Ribbon width is the number of people who made the move. Most arrive from Microsoft. Most leave for Meta (7% of recorded departures). Amazon Web Services (AWS) and Amazon are one company kept apart here, so the ribbon between them is a transfer inside it, not a move to another employer.

Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.

1,034 of the 1,035 people here carry an Eng Scorer tier.
Exceptional and strong are the top two of the five tiers. 179 of the 1,034 people here with a read sit in them, 17%. A tier is the band an Eng Scorer caliber score falls in, so this is the same measurement as the median on the caliber card, opened up.
Whether a title rose here
The level of the first title recorded here, against the last.

819 of the 1,035 people here had a title that could be placed on the ladder before and after.
A title rose when the last title recorded here sits higher on the ladder than the first; for someone who recorded one title here and then left, it is measured against the first title of their next role. The ladder runs intern, junior, mid, senior, staff or manager, principal, director, VP, then founder or C-level. A title that matches no rung is left out rather than guessed, and product, program and project managers are left out entirely, being a different ladder. That leaves 819 of the 1,035 people here classified, and it leans towards people who have left: someone still here on a single recorded title has nothing to be measured against.
