Is there a service that fires when Mautic runs that I can use to start my process?

I have a process (plugin) that needs to run a couple of times a day, but not at a specific time. For example it needs to run this afternoon and sometime in the early morning. Is there some hook that everytime Mautic runs, our process can quickly check the system time, and run if it is appropriate?

Sure, I can use a cron job, but I am really trying to make this as easy on the end user as possible. Since so many other cron jobs are running, I thought when those fire throughout the day, I could have that fire my process as well.

I am technical, but not on symfony. I am trying to direct my team that are good with symfony, but not Mautic.

Let me know if I need to explain in more detail.
