This is what I found in the FAQs of the program
http://www.albertacanada.com/immigration/media/h1b_FAQ.pdf"I don't see my job title on the Regional Occupations
Under Pressure list, am I eligible?
We do not assess your application by your job title, but rather
by your job description. To determine whether a Candidate's
occupation is under pressure in Alberta, a Candidate should
first reference the National Occupational Classification
(NOC) website to determine the four digit NOC code that best
matches their current job description. The Candidate should
then consult the AINP Occupations Under Pressure List
for the Strategic Recruitment Stream – U.S. Visa Holder
Category to find out if their four digit NOC code is on the list.
Please provide all of the supporting documentation requested
on the application form to assist us in determining if you are on
the above mentioned list."
In my case I am a software engineer... but when I applied in Jul/08 the only NOC available was 2171... I remember I sent a letter along with my application explaining why some of my current duties matched 2171... At the end I received my Nomination as a Software Engineer or at least that is what the approval letter stated....
I hope this helps...
