That title should be reserved for those that have the same credentials as an ME, EE, etc. Someone who is a CS degree holder or a self taught comp dev have in no way the same training as someone with a CE degree.
Engineers are able to take their PE exam in either CE or SE. https://ncees.org/engineering/pe/
Provided you have a PE credentialed coworker who can vouch for you. That is a chicken and egg problem for most people in an organization with no PEs.
