I'm a software engineer. I recently started a new position with a new company and have been with the company about 5 months.
In this short time I have shown myself to be a technical expert, as I came in with extensive experience in various technologies they use, and I have become a subject matter expert as I have shipped multiple completely new services that I developed in their entirety.
I feel I am outperforming my role and I would like to be promoted to a more appropriate level (and pay grade), but I fear that my short tenure would lead them to immediately shut down the conversation.
How soon is too soon to ask for a promotion? Would it be inappropriate this early?
