I've worked part-time for the past 10+ years now, at Google, Makani, and Elemeno Health [60%, 80%, and 40% duty cycle respectively]. It's awesome for work-life balance if you can swing it, and a lot more productive than many people would think.
When I came back from paternity leave with my first child, I told my boss I really wanted to go part time, and he supported me. Google had a standard easy of doing it, so it was just a matter of getting approval up to VP level, which went pretty smoothly.
When I applied to transfer to Makani, we negotiated a bit, and decided that I'd go up to 80% because I really wanted the job and they apparently really wanted me.
With Elemeno, I was already advising the company when I left Makani. I got a layoff package and didn't need paying for a while, and they couldn't afford me anyway. So we decided I'd help them temporarily until they could afford a full time engineer, and they paid me in stock and minimum wage. After about 18 months our agreement expired just as my COBRA was running out. I helped them draft a requisition for my replacement, but it didn't really make sense. For a bit more than they were paying me for 2 days a week, they'd maybe have been able to hire someone with a year's experience who'd be getting less done in their 5 days a week. So I switched to salary+benefits (some of the salary going to pay the other 60% of the health insurance) and that's worked great ever since, even now that we've been able to afford more full time engineers.
Incidentally, we're hiring for a number of areas right now, including engineering. We're aiming for full time, but it is a very flexible, diverse, and family friendly workplace.
I'm not the hiring manager for any of our open positions, so I can't make any promises. But we're a flexible place, so I wouldn't be surprised if some of the positions were part-time-friendly.
Oh, and outside of work I spend a lot of time co-parenting 2 kids, cooking (especially since covid), doing personal projects, practicing guitar, exercising, etc.
