I am an infra SWE with a decade of experience (34 years old), the last few years focused on distributed systems (think Kafka, Kubernetes, etc).
I have mostly an individual contributor role but I also work as tech lead for a few projects, planning and splitting the work for more junior engineers, and being ultimately responsible for the technical choices of the team.
I would define myself as absolutely average, I am not a brilliant developer and most times I find it hard to dig into a codebase and understand it, or entirely follow technical conversations with my peers. I have no “popular” work in the public to my name, if you googled me nothing substantial would show up, just a few sparse messages in open source mailing lists.
I am at a hedge fund. My role at FAANG would be paid around ~$600k/y (had actual offers at hand in that range).
