The scale of engineering problems is real: you get exposure to systems operating at a size most companies never reach, and that's genuinely valuable for a resume and for learning distributed systems. Ownership is high, teams are small, and you can end up owning a service end to end, including on-call, rather than being one of fifty people on a monolith. Internal mobility is easier than at most companies if a team or org isn't working out. Exit opportunities are excellent, Amazon alumni are everywhere, and the brand carries weight.

The Leadership Principles aren't just a poster on the wall; they're baked into performance reviews, promotion documents, and even everyday phrasing in meetings, and a lot of engineers find that culture forced or exhausting after a while.

Work-life balance is genuinely team-dependent, and the variance is wide. Some teams are calm nine-to-five operations, while others have brutal on-call rotations, especially around retail's peak season, like Prime Day and the holiday quarter, when code freezes and long hours become the norm regardless of your team.
