In your field, I don't think it will be too hard. It's just figuring out the steps.
I would check out the UKBA website. There is the Tier 1 (post-study) option and the Tier 1 (general). The post-study option will give you permission to remain and find a job, especially as an engineering graduate through the SEGS. However, you will be expected to transfer to another Tier 1 permit as soon as you are able.
I don't know much about the post-study option, but I'm sure someone on here does. If you have work experience and have enough points for the Tier 1 (general), I would try to go for that. That is just my opinion since you will eventually have to switch over anyway. However, someone more knowledgeable may see it differently. The Tier 1 (general) consists of the Highly Skilled and Sponsor Skilled options. The former allowing you to go to the UK without a job offer. However, you will have to show funds to support yourself.
I would suggest checking out the site below. Also, there are the forums for the Tier 1 (post-study) and the Tier 1 (general). You may find those more beneficial, especially once you have more specific questions.
