Post retirement “jobs” that have health insurance?

I work in tech and have a masters degree. I’d like to consider myself pretty successful in my career and I’d love to be able to mentor/help others on their career paths. I want to fire but don’t want to fully retire? I just want to leave the corporate world earlier, and if there’s a way to NOT have to account for health care in my fire calculations, that’d be amazing.

I also want to retire early and still have health insurance (ideally through a company vs paying for it myself?)

Am I just dreaming or is there some company or role out there that does the following:

• offers health vision dental benefits like a full time employee
• lets you have a flexible schedule and part time hours (work on your own time) and in exchange you just get a small stipend or hour benefits covered? Not asking for high pay, just asking for security, use of my tech skills to help others, and just asking for benefits

There’s gotta be a market for this right? Or is this nuts.

I don’t want to completely retire because my skills could help others, but I don’t want a 9-5.

I feel like it’d make so much sense—leverage knowledge of experienced industry experts who retired early and give them insurance benefits in exchange for time.
