The first specialty chosen by an Engineer should be ‘Basic Engineering’, which corresponds to large carts and water/wind power.
Next should be ‘Mechanics’, which corresponds to the age of steam and steam powered vehicles and generators.
Then ‘Oil Drilling’ and the first oil wells, kicking off production of oil as a fuel and eventually leading to the invention of plastics.
Next should come the ‘Electricity and Electronics’ specialty with the harnessing of electric power and eventually electronic components.
Finally, ‘Advanced Industry’ would be unlocked as a marriage of electronics and mass production, allowing things like the robotic assembly line.
I'm assuming the main work needed to make this happen is recipe alterations and other tech tree changes to when engineers get access to what, in addition to the re-names.
