Got a PSE offer from Google. Should I join?

Please help me make a decision... I recently landed a Product Support Engineer role at Google, and obviously, they are paying well (RSUs, sign-on bonus etc.). However, being from an SDE background with 3 yoe, I'm a bit concerned that making this switch to a support profile might affect my long-term career goals as an SDE. Should I go ahead with the offer or not?
