Would you identify as a junior

[Jonnybmac]

When is a junior role is it correct to identify as a junior engineer?
Should i title my email footer as junior mechanical engineer and introduce myself as a junior face to face or just a mechanical engineer?

For me it doesn't bother me to know my place but is the title as well as the position entry level?

Thank you for the help. As stated it doesn't bother me to show who I am if anything I would rather come under my job position than people have expectations that I'm better than I am I just didn't want to look silly if nobody puts it in their email etc.
