English to Bulgarian Bus/Financial Management

We ask people to provide some biographical information about themselves when they complete our online questionnaires. One of the things we ask them to specify is their level of responsibility within their organisation. 'Enterprise/corporate manager' is one of the possible options. This role is defined as follows: 'Board member of large, multinational enterprise e.g. Chairperson, Corporate Chief Executive Officer of multinational corporation or enterprise'.

Any suggestions as to how to translate this would be very gratefully received!

Thanks!
