I work at a kids media company that makes books, apps, activity packs and other entertainment media based around teaching kids computer science, tech safety and stuff. My job title is "Creative Associate" because nobody can really pin down a single job title for me, so I describe it as "All-purpose Creative Stuff-doer" and my boss describes me as "A Swiss Army Knife".
I do a mixture of writing, activity or games design, illustration, developmental editing and even sometimes graphic design and art direction... basically whatever's needed.
I worked as a full-time freelance illustrator for a while, but it was exhausting and stressful. I never had creative energy for my own projects and just spent all my time working on other peoples' and doing admin or seeking jobs. This works a lot better for me.
