The error is the verb "are emerging".
Explanation:
The subject of the sentence is "A class" (singular) requiring a verb for a singular subject:
"A class of engineers, called 'knowledge engineers', is emerging to support the experts who are employed as independent consultants."
The verb in the relative clause is correct:
"...who are employed as independent consultants."
The relative pronoun "who" refers to the plural noun "experts".
