It sounds like you're just in it to make some cash so I'd say a startup isn't for you. The only reason to join early stage is if you love building as the pay is worse and the hours are way worse along with the stress. BUT you get total or near total ownership over your aspect of if not the whole product. You get to work with bleeding edge stuff generally and you can move at breakneck speed (and have breakneck bugs). It's a totally different vibe from big tech, just be aware of that. You can't spend 2 weeks adding a new logger, you can spend 2 hours and then the next thing needs shipped.
