No, its not. It does expand out to have a repeated word, but the reference is different (the HR resources -- Human Resources resources -- are resources dedicated to the Human Resources function.)
Let alone the other answer ("HR" == "other engineers"), which is brilliant, the HR department is the greatest weapon a large firm can deploy. Do you want insurance in case your kids get sick? Do you want days off to relax after a month of hard work? Do you want to ensure your boss ain't making inappropriate advances?
Why on earth would a smart people want to be burdened with all of those works? Why on earth would a smart people hitch non-core work onto main work hour? Why on earth would a smart person refuse to delegate?
"HR resources" is redundant. Such arrogance.
