You might see it in:
* Academic contexts: like "Engg. degree" or "Engg. student".
* Professional titles: like "Engg. Manager" or "Engg. Consultant".
* Company names: like "Engg. Solutions" or "Engg. Services".
However, it's important to note that "engg" is not a widely accepted abbreviation in formal writing or professional settings. In those contexts, it's best to use the full word "engineering".
