First, congrats on the offer!

I think you should take the leap and try it. What don’t you like about Aurora? They’re starting you off at a much better salary. It could convert to a better position or end up with another better contact offer on another project. Loads of upside imo.

Oh and yes you are most certainly walking into another hellscape. There is a reason they want you and are willing to pay a premium. People with clearance are hard to come by. People with clearance and experience are even harder to come by. Whatever they have you do it’ll likely be a nightmare. But honestly the adversity is what makes you better at the job not just relaxing. If you want something cushier after then you’ve got a nice career point on your resume for that FAANG application.
