Hi,
I would not be too concerned about the job title- it is far more important to show progression via the letters and the rest of the application package.
As an aside, I would consider UCLA part of the "top 10" or "elite" cluster. For those who read BW, UCLA was 9 in 1994 and 10 in 1990. Its lowest ranking in BW was #16, better than the lowest ranking of many other elite schools such as Yale, Berkeley, and NYU. The acceptance rate was about the same as or lower than the acceptance rates of many other elite schools including NYU, Yale, VA, Cornell, Michigan, and Duke. Likewise, the yield equalled or exceeded the yield of several other elite schools including Dartmouth.
