Many people get to know of jobs before the job is posted to the web. This is what you need to do.

But it's important to register, just a few basic details, so they can put you forward for jobs and receive their email alerts for jobs. Submit a dummy cv or resume to get into the system and get daily jobs emails .

You could set up a free email. Which you can abandon later. Use an alias. Tell them that you will submit your cv or resume to the employer or agency yourself by post if you prefare.

Just give basic details job type , engineering experience , location and so on . Leave out the persoanal detail. This way they do the work and the jobs come to you. Work smart!
