Technology career
Immediately following his graduation from Cal Poly Pomona, Williamson moved to Silicon Valley. For the next fifteen years, he worked for Advanced Micro Devices in San Jose, California, designing products around its chips. His coworkers never inquired about his earlier career as a rock musician; in a 2010 interview with Uncut, Williamson asserted that many of his colleagues were "nerds and geeks ... they don't listen to The Stooges much."[17] In 1997, he was hired as Sony's vice president of technical standards; in this capacity, he liaised with competitors and helped to codify nascent industry standards, most notably the Blu-ray Disc. During the Great Recession, he accepted an early retirement buyout offer from Sony in 2009.
In 2015, Williamson was selected to receive ANSI's Ronald H. Brown Standards Leadership Award for his contributions to consumer electronics standards development. The award, named after late United States Secretary of Commerce Ron Brown, is presented as part of World Standards Day celebration.
