Unless you're in a <10 headcount everyone-does-everything startup, by the time work reaches software engineering it's already been determined as having good business value. It's rarely a software engineer's job to challenge that determination unless new information emerges that wasn't factored into the original decision.

Also, maybe my perspective is skewed from only ever working at gigantic companies but what usually grows a career is making your manager's life easy - becoming someone who reliably gets shit done on time and without drama.
