I'll make a guess to get the conversation going, but I'm interested in what others have to say. I'd guess a new PhD would get $150k and a bonus between $50-100k. After a while, it will be more clear what contribution his/her research has made to the PnL, and the bonus will rise accordingly.If you are asking for yourself, I wouldn't even worry about it. Just take the job. If you get the opportunity to contribute to trading models, your career will take off. Your base salary is only intended to give you enough stability to pay your rent, but the potential bonus upside is huge. So don't pass up an amazing opportunity just because another job/field has offered a higher starting salary.
