Probably one of your main considerations should be how you are left if the startup dies. There's plenty of good advice here about how to pick a startup that might succeed.

So there's a few considerations:

- Have you got some savings, in case it dies suddenly? You need to be able to pay rent until you find another job. Hopefully the startup is located near these other jobs.

- Does it allow you to build on existing experience? If you can claim you're in the same industry, you're not losing much (perceived) seniority by trying your luck for a bit.

- Does it give you an easy promotion? This is probably one of the main things a startup can offer. Just being able to add "Senior" to your name or "Team Lead" a few years before you would in BigCo might be worth it.

- Do you get to work with the tech that you want for your CV? You probably have an idea of what's hot to have on a CV, and a startup is relatively new, so maybe you can direct things that way?
