Part time work is possible.

I initially dropped to 4 days/week in lieu of a payrise (comp remained the same). Did that for a while and since then I've been working 2-4 days/week (3 right now)

It helped that it was a small company and I had been working there for 5+ years, not sure how I'd go about finding a part time software job otherwise. Everything is negotiable though.

I would second this and add that moving to part time is a path that your manager can help you talk to HR about. They may ask why since its not common and just be honest about it. If its medical related - taking care of spouse, parents, or kids then in the US there is FMLA which can be up to 12 weeks, pay depends on banked time off and insurance, etc.

In the US there are likely medical benefit and retirement account requirements for working X hours per week, I think its 32 typically but check with HR or if your place has an employee manual it should be clearly spelled out. To phrase that another way - you may lose medical coverage and/or 401k match depending on the "hours" you work. Scary quotes is because you are likely still salary and not hourly.
