I am in the exact same boat. All my work experience is gained under NOC 1225 but my education is absolutally different from what I do for a living. I am not an expert but from what I know EE does not require you to have work experience based on your education. You recieve some CRS score for your work experience AND for your level of Eduaction and the subject of your studies.
So, having ECA for bachelor degree gains you some points and having work experience gains you points also. It does not matter if you worked as an engeneer or not. What matters is that 1225 falls under B category which gains you points for work experience. However the subject of studies might or might not gain you points (like, if you studied Law outside of Canada, I do not think it gains you points). So, do not wait anymore and apply for EE. You are eligible!
