A UK working VISA is further separated into those who have a job already in the UK, and those who are looking for work.

1. In the first case the UK company who hired you should provide the necessary details for your Work VISA to be issued.

Highly Skilled Migrant Program Point System for Qualifications

2. In the second scenario you would fall under the Highly Skilled Migrant Program. This is not given freely and the applicant must meet certain criteria before such a skilled migrant work VISA can be obtained and this is based on a points system.
Below is an example for the points system requirements for skilled migrant workers VISAS in the UK:
PhD = 50 points
Masters Degree or Professional Level Qualification = 35 points
Bachelors Degree = 30 points
They'll also ask how much you expect to earn and there are points assigned here also.
5 to 45 points depending on your expected earnings (there is also a country of residence factor)
Additional points are awarded if your previous work experience was gained in the UK on a working holiday Travel VISA.
