Gearbox Protocol is transparent both in code and processes. On the Team: Contributors & Initiatives page (and then in Monthly Spending Reports) you can gauge the relative USD(C) salaries and GEAR bonuses on top of that for different positions. Your concrete offer will depend on your experience and skills, but the pages will give you a rough estimate of the numbers.

Good luck!
