Most jobs in the architecture/modelling/design/verification roles are basically like software roles (in terms of working patterns / work environment). So, fully remote, hybrid and fully on-site are all possibilities. Hybrid (1-3 days per week in-office) is probably the most common arrangement I've come across in the UK.

If you're moving into stuff like physical design then you start to get involved in chip bring-up, in which case you need to be in a lab which you're unlikely to be able to build at home. That's when on-site starts to become a requirement.
