We are definitely looking for product managers, along with software engineers (e.g. backend, frontend, SRE, data science, security, cloud, API design) and designers (e.g. UX research, service design).
For product marketing, the closest role to that might be content strategy, which has proven quite useful.
We don't really end up building many apps, so you're probably better off finding a closer match to your interests/skills. Sorry to be the bearer of bad news!
