I think it's because the company lost a Python engineer or Java developer and is looking for a replacement. You could take it as a red flag that it's not a system design position and more of a maintenance role, but then again they're asking for a "developer" and not a "designer" or "architect". So the hiring company is being pretty direct about what they want.
