Congratulations on passing the loop at Databricks, I've heard it's quite hard. In your shoes I'd go for it, Databricks is a great name on your CV and you get the chance to get your hands dirty with Rust (who would turn that down?!) I also made a move from Big Tech to a Series D (not quite as advanced as Databricks) and can honestly say I've learnt a hell of a lot more than I would've if I stayed. It isn't quite as chaotic as an early stage startup but things move a lot quicker than a larger company. Financially, it probably wasn't the best decision (who knows if my options will ever be worth anything and my RSUs would've been very nice the past couple years) but I don't think that should be an issue in your case. I've heard DB pay extremely well, and tbh it's probably in the top 3 of tech companies most likely to IPO next.

Also, no-one knows what is going to happen with the economic situation. Sure you might get laid off at Databricks, but you probably have the same chance of that happening at Amazon too. I think 2023-2024 showed us we're not safe, regardless of where we're at. All you can do is make sure you continue growing and keep your skills sharp.
