Are there opportunities for advancement for ge medical aftermarket software system service technicians

Hello, there are opportunities for ge medical aftermarket software system service technicians to be promoted. Generally speaking, the treatment is okay, in 2020 when I resigned from one of the three major medical companies (my work experience is relatively low, belonging to the kind of 0-3 years), a year's salary, allowances plus year-end awards plus travel subsidies, get more than 7000. At the same time, medical after-sales software system service technicians belong to the highly skilled personnel, promotion opportunities are great.
