I've never felt able to use "engineer" for myself, but I don't perceive this badly. My official title is "software architect" though most of my day is not spent on architecture.
It's a bit postmodern of me but does anyone's title mean much? Short of very specialized work, one must have multiple skillsets for the different roles they are cast in on a daily basis.
I have to do the following, fairly regularly:
1. Write Code
2. Write Specs
3. Customer Service
5. Write Proposals
I'm owning up to a lot of stuff, particulary #7, that I would never admit to for the sake of saying that most jobs these days require multiple intelligences.
Think Santiago Calatrava: engineer, architect, artist. And he deals with clients, too.
