To me, the only benefit of joining a startup is in startups you're usually given tasks for which you're not qualified for. But I wouldn't join a startup if startup doesn't offer me compensation package (salary + stock option) at least at market average.

Engineers generally have worse data about market averages. It's better to get some offers and get a feel for what that engineer can reasonably expect. Then at the negotiation table, she can either argue for market average or provide anecdata that they are are an above average engineer as far as market rates are concerned.
