Shortly after graduation, Jay was employed as an Analysis Group Manager with VertexRSI in Kilgore, Texas. Jay oversaw the stress analysis of large-aperture satellite antennas, supported the manufacturing department optical tooling program, and conceived a light weight trussed subreflector support assembly for a high frequency 20.1 meter satellite antenna. This design resulted in a 60% stiffer and 50% lighter assembly than its predecessor. In 1995, Jay took a position with CommScope (formerly known as Andrews Corporation) in Denton, Texas, as a Mechanical Design Team Facilitator for the Earth Station Antenna Group. During this period, Jay developed a mobile lightweight satellite antenna structure and drive system. The resulting design was 35% lighter and a 40% lower stowed height than the previous model. In 1997, Jay was promoted to R&D Manager for the Tower Division. Jay was able to reduce tower bid turnaround time by 30% through the utilization of statistical data in conjunction with spreadsheets. Jay left CommScope and became the Senior Staff Structural Engineer for Metricom in Plano, Texas.
