Can I move to another job despite of the non confidentiality agreement all of us in the company are required to signed?

You should definitely talk to an employment attorney before making any decisions about separating from this employer. Covenants not to compete are lawful in Florida, and disputes over non-competes usually wind up getting resolved in favor of the employer. Depending on the wording of your particular agreement, it might be possible to continue to work in your field but not in the same capacity. Anyone giving advice would need to read the entire agreement; but, based solely on what you quoted in your question, I already see one potential problem with it. I cannot envision a court saying that you could not go to work at another company in competition with your current employer as, say, a receptionist or a janitor, positions that have nothing inherently to do with interior design. Granted, you might not ever want to take such positions; but, the language you quoted says it's not possible. Other parts of your agreement might have other problems. Go show it to an attorney to find out your options.
