How to find less-competitive faculty positions in the US universities?
Although (see my comments), I cannot recommend this sort of career path, here are two ways for an outsider to determine which positions will be less competitive: 


Teaching load and pay. If the pay is poor, and the teaching load is high (say, 4/4 or higher), then the position will be less competitive. 
Look up the average SAT scores (easy to find via Google) of American schools to which you are applying. This is a reasonable (although not perfect) guide for the quality of the undergraduates that these schools enroll. Schools with lower averages will have less competition for faculty positions.


That said, all faculty jobs are highly competitive.
