How large is this company? If it's a small- seed/series A startup, I think it's expected you give 100% if not 130%. If you want something more laid back, perhaps you should focus on larger companies with 1000s of employees.

With that said, I do believe you should "care" about your work. Even if one task isn't the most exciting you should still care about the quality of code you contribute. After all, you will be judged by that, more than your time management skills.
