Responds to situations where first-line product support has failed to isolate or fix problems in malfunctioning equipment or software. Reports design, reliability and maintenance problems or bugs to design engineering/software engineering. May be involved in customer installation and training.

In a less sophisticated environment, as with many applications products where the user is nontechnical, this position would generally interact with product support personnel and potentially the customer when the customer’s problem cannot be resolved directly by first-level resources.
