Flexijobs (mummyjobs.co.uk) can have really well paid opportunities depending on experience. Also you can look for WFH/remote on the main jobboards these days as a filter. Most want hybrid rather than fully remote, but they are out there!
I work in the energy sector and they're always recruiting. Pays fantastic and it works perfectly around kids I do it with my kids in tow . If you'd like to message me, I'd be happy to give you more info x
Look at your local authority, they're mostly hybrid now but flexible hours etc 😊
