 from 1992–2000, and at Pemstar Pacific Consultants from 2001 - 2005. All other times he has worked either as a free-lance consulting designer or for his own design firm.

Many of his designs were leaders in reducing the costs of computer technologies for the purpose of making them available to large markets. His work featured a concern for the social impact of technology. The Community Memory project, begun as a project of Resource One, Inc. in 1972 and later incorporated in 1977 by Lee with Efrem Lipkin and Ken Colstad, was one of the earliest attempts to place networked computer terminals in such places as Berkeley supermarkets to attract casual use by persons from all walks of life passing through and facilitate social interactions among non-technical individuals, in the era before the Internet.

Lee was influenced in his philosophy by the works of Ivan Illich, particularly "Tools for Conviviality" (Harper and Row, 1973). This book advocated a "convivial" approach to design which allowed users of technologies to learn about the technology by encouraging exploration, tinkering, and modification. Lee had learned about electronics in much the same fashion, and summarized his conclusions in one of several aphorisms, to wit - "In order to survive in a public-access environment, a computer must grow a computer club around itself." Others were - "To change the rules, change the tools," and "If work is to become play, then tools must become toys."
