This is the Gearford system, many major cities in Antiford use this template including Argenstrath, Astam Junction, and White Haven. Smaller towns will often combine responsibilities down to a single individual or do other adjustments to minimize as the town's size calls for.
The highest position in Antiford's metropolitan government is the position of Mayor, known as the Mayoral Chair. This is a holdover from pre-technocratic days and not outlined by any technocratic philosopher of the past.
The mayor has the power to organize councils as they see fit within their city.
These councils are lead by a Chair, which the members vote for amongst themselves to decide.
They also elect others in their fields to represent them in the national House of Engineers, which must be approved by the mayor.
There are a set of typical councils expected of a mayor to organize, or they come under federal scrutiny, and in extreme cases, investigation.
