Ideas for volunteering as an EMT in or around Seattle?

So, I live in Ballard and am employed full-time in tech (working from home 9-5, M-F), but I got my NREMT certification last May in Oregon while in the throes an existential crisis about not making any meaningful contribution to society. I have no intention of leaving my cushy tech job in this market, so I’m just looking to volunteer or work very part time by the end of May because that’s when my eligibility to get a Washington license ends.

I’ve looked everywhere for options, from researching rural fire departments to hunting for part-time work as an ER tech in the city, but most of them require a more regular/substantial time commitment than I can reasonably manage with my current job/life schedule.

Does anyone know of any nearby volunteer or (very) part-time EMT opportunities I could check out? I’m hoping to find something that’s down for a bit of irregularity in my availability. I’ve heard of people volunteering at concerts or with youth sports leagues, but I haven’t been able to actually find any solid info on things like that yet.

Thanks!
