The thing you want, low stakes low effort programming, doesn’t really exist. The reason Google can survive building everything themselves — and thus giving you and many others endless code to write — is because they have exceptionally deep pockets and army’s of people.
Outside of Google-type companies, people write code to serve a direct business need which means the impressive software engineers are not the people who write good code but rather the software engineers who can use technology to benefit the business — which sometimes means writing code, but often does not.
If you go to a smaller company, even in a software engineering role, even as an individual contributor, expect to spend a lot less time having fun programming and a lot more time solving business problems.
You can absolutely coast in a low stakes environment at a smaller company, but don’t expect that being able to write Google-quality code will impress anyone. At a pragmatic company, people are more impressed by whatever benefits the bottom line. If you’re not a natural at the business side of things, it’ll be much more challenging to impress at a small company than it would be to impress at Google.
