cnewby@cimarronsystems.biz
Charles F. Newby, founder and principle systems engineer, is a skilled executive with broad experience successfully developing lines of business based on new technologies for the categories of interactive television, high-speed data, and telephony services delivered via broadband cable, satellite, and wireless networks deployed by commercial and governmental customers. A key factor in that success is the use of a rigorous, realistic product development process that begins and ends with the needs of the end user.
Before founding Cimarron Systems, Mr. Newby held key business development, program management, and engineering positions at several major corporations including AT&T Broadband, PrimeStar, M/A-COM Linkabit, Megatek, and General Dynamics. During his tenure at these companies, Mr. Newby led a number of interdisciplinary teams with annual budgets in excess of $10M through the development of advanced products for applications that included multi-channel interactive television, high-speed data, and telephony services utilizing hybrid fiber/coax, satellite, and wireless transmission networks; special application DoD satellite and wireless networks delivering voice, data, and fax; avionics for DoD missile systems; and high-performance graphics processing systems used in the electronic design automation industry.
