I would need to explore your background further but some options are to do journal/conference review work (this is more available than many people realize) or try to obtain a higher level of membership at IEEE, for example, or other similar organizations.

Would participation in company-internal conferences/technical summits also count, other than the usual internationally reputed journals/conferences? Could you please elaborate on "this is more available than many people realize"? Thank you for doing this AMA.

Internal company stuff doesn't really help other than possibly to bolster that you're playing an "essential role" for your company. If you want me to drill down deeper and get into the specifics, send me your CV.
