I'm considering joining a startup that has raised a few million in Series A funding and I'd be the second developer joining the team. I've been out of college for 4 years and am looking for a senior developer role somewhere, either at a startup or a more established company. For better established companies, I've got an idea of the compensation to look for. For the startup, I have no idea. I'm not that concerned about compensation, but at the same time I know I'm going to have a big impact at this startup if I sign on and want to make sure I'm "fairly" compensated. I appreciate the risks of working at a startup and am willing (maybe even excited) to roll the dice. I just want to make sure I'm getting a fair deal.
With this little information, what should I be looking for? What percent of my non-startup salary should I be looking for? What kind of equity? How do I evaluate whether it's a good deal?
I've searched on Google and found the basic VentureHacks articles. Honestly, I know it's an "it depends" kind of question, but I just want to make sure I'm evaluating the offer I have fairly. So how should I go about this?
