Congratulations on your senior year! I think timing really varies across the board - at my company, we start recruiting May graduates in September and run through April. A lot of companies tend to recruit heavily on-campus in both the fall and the spring, so I would begin preparing your resume and your short "elevator pitch" as soon as you're comfortable. In terms of titles, they tend to vary from company to company, so I would pay more attention to the requirements of the job and less to the title. Many companies' careers sites allow you to set up job alerts based on a set of qualifications or criteria that you set, and that can be a great way to keep on top of new potential opportunities.
Congratulations again, and best of luck in your search!
