We just promoted a Senior Engineer who hasn't built a single new microservice in three years.
He didn't introduce Kafka. He didn't migrate us to Kubernetes. He definitely didn't implement a "GenAI Vector Database."
A Junior Dev asked me: "What exactly did he do to get promoted?"
I pulled up the repository.
Over the last 36 months, he deleted 45,000 lines of legacy code. He replaced a highly complex, failing Redis caching layer with a boring, properly indexed Postgres table. He automated a deployment script that used to require three engineers on standby.
The best engineers in our company are the ones no one talks about.
They don't build flashy things that get mentioned in tech blogs. They build invisible things that just work.
Amateurs add complexity to prove they are smart. Professionals remove complexity to prove they are seasoned.
