Can you break a rental lease because you're voluntarily transfering for your job?

No, you may NOT break your rental lease without penalty because you are transferring for a job. A lease is a contract; in entering into the lease, you entered into a contract with your landlord. Your contractual obligations are not affected by changes in your life, or that it would be better for you to move. In a case like this, the landlord may hold you accountable for the rent you would owe for the rest of the lease term.
