the.com/coordinator

means A person whose job is to organize people, schedules, and moving parts so that a group effort actually comes together.

from Traces back to Latin co- ('together') plus ordinare ('to put in order,' itself from ordo, 'row, rank, arrangement' — the same root that gives us 'order' and 'ordain'). 'Coordinate' entered English around the 17th century meaning 'of the same rank,' then grew a verb sense of 'bring into proper relation.' The job-title 'coordinator' is the newer, more modern layer — someone hired specifically to do the ordering-together that the Latin roots already promised.
