My concern is that given the brevity of a logline, every word should count, relate to something that is absolutely necessary to the conflict and outcome of the plot.
The general rule is that a character description in a logline should refer to a character flaw that is pivotal to the outcome of the plot; the character must overcome it in order to succeed. Or alternately, a character description could be a character strength or ability that is absolutely essential for the character to have in order to succeed.
If his being an architectural engineer is not pivotal to his success or failure in the story -- if he could just as well succeed (or fail) if he were a web designer or a musician or a plumber-- then that description is extraneous to a logline. Use it in your plot if that's the way you want to go, but I don't think it needs to be stated in a logline.
