It depends on the company's product. At a very large company you might find the odd team that's building some interesting new, internal framework or infrastructure. If you want to stay away from CRUD your best bet though might be a company where the CRUD isn't the core of what provides user value. Examples that come to mind immediately (since that's where I work right now) are data offerings. Lots of interesting new and existing data stores these days and unless you end up on the, likely very small GUI team, it's all hardcore coding. I would expect similar from some ML products.
