Pros
If you are self-driven and are able to constantly motivate yourself to go above and beyond, you should thrive in this environment. It is on you to get work done. There are mentors and engineers willing to help you and hold your hand, but ultimately you have to be able to carry your own weight. It is your responsibility to take charge of your learning and improving your troubleshooting skills. This is a good position for a recent graduate or someone switching over to the tech field because you're expected to start on a clean slate. The main pros are very good pay, control of your learning (you won't have someone constantly checking over you), and exposure to AWS services in a deep level. No matter what, you're going to learn.
Cons
Can be overwhelming the first few weeks because it is fast paced. The learning curve is steep, things will go 0-100 and there will be moments where you doubt you can handle this. Don't be surprised if you have to put in extra hours here and there in order to be up to speed with expectations. Easy to get burned out if you do not set work/life balance. It is difficult to build connections if you WFH and you're introverted but this is obvious.
