Ah! A fellow holder of the belief that time travel stories are better when they are internally consistent! I hate e.g. Looper for having time travel that makes no goddamn sense. It takes me out of the story when the characters are literally watching the timeline change before them as it magically radiates out from one point. And then our protagonists somehow remember the original timeline... Bah.
...So I must ask - have you seen Primer? If not, maybe you'd like it!
I worked in AWS for four years. While there I worked for two different teams.
The first team was the worst job I've ever had. I broke four molars in a year, grinding my jaw in my sleep.
The second team I had a great boss. Still one of the best I've ever had. But even at its best - I would never consider working for Amazon again.
I have a whole rant if you want one, but suffice to say that in Seattle - where Amazon, Microsoft, Meta and Google all have campuses - Amazon is widely considered the worst of the lot.
Amazon: Worst life balance. Worst dev equipment. Burns people out and uses golden handcuffs to trap new hires. But hey, sometimes the desks are made of actual doors and 4x4s.
Microsoft: boring and political AF, but you can get a private office.
Google: restaurants and best dev equipment, but the work is largely dull - they have enough world-class experts in X that you probably won't get to do anything interesting.
Meta: is contributing to the erosion of our civil society. But a lot of cutting edge VR/AR stuff is happening out here, so that's cool.
If you want stability and comp, I'd recommend applying to Meta or Microsoft. Both pay as well or better than Amazon and have a harder time with recruiting, making them slightly slower to churn through employees.
Alternately, if you pursue Amazon, note the following:
Finally, there's nothing special about the "Big Leagues" - 99% of the job is still glorified string manipulation. Don't let that idea intimidate you. Most of the best engineers I've worked with were at small companies (5 out of the 6 or so that come to mind - only 1 was an Amazonian engineer). I saw plenty of bad code inside the walls of Amazon - the industry skill level really is a lot more flat than companies like to pretend.
