While at UCLA Crocker taught an extension course on computer programming (for the IBM 7094 mainframe computer). The class was intended to teach digital processing and assembly language programming to high school teachers, so that they could offer such courses in their high schools. A number of high school students were also admitted to the course, to ensure that they would be able to understand this new discipline. Crocker was also active in the newly formed UCLA Computer Club.
Crocker has been a program manager at Defense Advanced Research Projects Agency (DARPA), a senior researcher at USC's Information Sciences Institute, founder and director of the Computer Science Laboratory at The Aerospace Corporation and a vice president at Trusted Information Systems. In 1994, Crocker was one of the founders and chief technology officer of CyberCash, Inc. In 1998, he founded and ran Executive DSL, a DSL-based ISP. In 1999 he cofounded and was CEO of Longitude Systems. He is currently CEO of Shinkuro, a research and development company.
