George is currently working as a maintenance and reliability engineer at the W. M. Keck Observatory on the island of Hawai'i.

From 2004 to 2017 George was a NASA engineer at the Kennedy Space Center in Cape Canaveral, Florida, specializing in avionics. George helped repair, upgrade, test, integrate and launch space shuttles from 2004 until the orbiters were retired in 2011, working his way up to Lead Guidance, Navigation and Flight Controls engineer for Space Shuttle Endeavour. In 2009 George was promoted to Flight Program System Engineer and assisted with the GNC design of NASA's Orion spacecraft concurrently with his shuttle work. For three years George worked in the Launch Services Program, consulting on flight computers for launch vehicles such as Falcon 9, Pegasus, and Antares. He also lent his avionics expertise to next-generation commercial space activities and advanced technology demonstrations, like small-scale orbital class launch vehicles as well as nanosats and drill-mounted fiber optic sensors for asteroid and planetary characterization and prospecting.

During his time at the Cape, George worked extensively to promote NASA, serving as a VIP escort for launches, a tour guide for educators and students of all ages, and a resident rocket expert for visiting schoolchildren and educational programs online and on NASA TV. He represented NASA as a judge for statewide science fairs and two Swarmathon competitions, which challenged university students to develop bio-mimicking software for controlling swarms of robots designed to collect resources on other planets.

George has bachelor's and master's degrees in aerospace engineering from the University of Tennessee. For five years he split time between NASA and the University of Central Florida as a Kennedy Graduate Fellow, pursuing a PhD in Planetary Science, before being called back to avionics engineering full time. While working on his PhD, George spent seven months on a work detail to KSC's Swamp Works helping to develop a simulated asteroid regolith from a mixture of processed minerals available on Earth.

George and his wife Lorenia have four children: Rafael, Io, Leonardo, and Andromeda.

He is an active member of the Bahá'í Faith.
