Need some tips to make my resume stand out

Hi

I'm trying to find a way to make my resume captivating because I want to find a new job. The thing is I have a Bachelors in Computer Engineering and my work experience has been in three somewhat unrelated fields.I first worked as a technical/helpdesk support senior analyst for a year.I then worked as a network communication analyst for 3 months and then I worked as an electro-mechanical engineer on site in the middle east for a year. My work experience looks diverse and I don't know if the fact I've switched jobs within this short time is good or bad.So basically I do have basic experience in those fields as I only spent a year in each job but it may not be to my advantage. I don't really know. I want to find a way to put my work experience in way that is captivating to companies.Again,I'm confused about what kind of companies are going to look for people who worked in different fields for a very limited time.What kind of info shall I put or omit in my resume?

I'm so confused about that.Any advice or help is appreciated.

Thanks in advance
