My job title is Marketing and Program Developer. It's pretty meaningless.
I work for a not-for-profit Canadian ebook digital service provider. We do things like digital distribution, book conversion to ebooks, marketing initiatives, and professional development. I started there as an intern a year ago and now I have moved from the more boring side of digital distribution/conversion to the much more interesting marketing and professional development side.
My day to day is split between helping publishers get their books promoted on Kobo, Amazon, etc. and putting on events, webinars, and writing tutorials on topics related to ebook production and marketing. I also am in charge of the social media and updating/maintaining our website.
I like my job, but I am not getting paid near-enough. As a result I've been actively looking for something else. I came close to working at Simon and Schuster doing digital marketing for them, but it didn't materialize. My current employer is also in danger of losing its funding (we're largely government funded) so I really should be spending more time looking for something else.
I also moonlight as a book designer. My current project is a scifi novel cover for both print and electronic editions.
