At an organization as large as DoorDash, that simply isn't true for IC engineers. Their job is to implement the product requirements. It might be more sensible to provide the option to do deliveries, to the engineers who are interested. Their voluntary interest in improving the product is a positive sign that they may develop beyond their current role. Edit: I meant to add, as others mentioned, there are other departments who would more benefit from this program. As I suggested above, the product requirements come from a long line of bureaucrats: the product designers and business analysts are primed to make the most of this program.
