Hi,
are you funded? you need to check with the regulations, normally you can't do more than 20 hours per week.
Do you have the time to work? In my second year I had to do the case studies, so it would have been impossible....
Check with your university services, as they can help you with the cv. There are different CVs for industry and academia. In many jobs you will need to write a cover letter, which takes up sooo much time (and is boring).
You can search for Research assistant jobs in your department, some students are offered teaching jobs (but not getting paid).
