From 1975 to 1976 he taught two original metaphysics courses exploring Immanuel Kant, Arthur Schopenhauer, Ludwig Wittgenstein, and Eastern philosophy in light of theories of philosophical reticence. Jungleib then pursued graduate work in philosophy at the University of Rochester, advised by Richard Taylor and Lewis White Beck. As a Graduate Fellow, he taught undergraduates Introductory, Modern, and Eastern philosophy courses while focusing on Plato, Metaphysics, and the Philosophy of Language. He began his Silicon Valley technical career in 1977, as a trainer for Deterline Corporation. Here he behaviorally revised radar and other non-ordinance instruction for the U.S. Army Intelligence Center and U.S. Navy. Next he edited and wrote for AMPEX corporation, creating documentation for broadcast audio and video recorders. While studying emerging mini- and micro-computers at Stanford University and Foothill College he created a publications department for clinical chemistry analyzer maker Chemetrics. In 1979 Jungleib joined Sequential Circuits Inc., a prominent synthesizer company, where he managed publications for the company's musical instruments such as the Prophet-5, and other Engineering programs. His detailed documentation helped solidify the company's success among music's most influential artists of the 1970s and '80s. Jungleib's tenure at Sequential also evolved into over 30 years of leadership in music synthesis, including coordinating MIDI (1983), General MIDI (1990), and ultimately, inventing real-time processor-based synthesis (1993) and its means of distribution (1997). After Yamaha Corporation's KORG division absorbed Sequential, Jungleib consulted as Product Planner to finish the Wavestation and develop Sondius® physically-modeled sounds. Now independent, he consulted on MIDI tools for Silicon Graphics, further exploring multi-media design by becoming an early Macromind Director certified developer. Director synchronization problems motivated his first patent (#5,286,908), which forged bi-directional linkage between graphics and music programs. He employed this technology to implement California Recording Institute's visual virtual mixing system. In 1991, while serving as MIDI and Audio Curriculum Director for Cogswell Polytechnical College, semiconductor giant Intel approached Jungleib to invent an unprecedented real-time software music synthesizer—within the limits of personal computing. At first the project targeted a DSP chip, but by mid-1992 the platform had become the 486 CPU itself. To achieve this paradigm shift, Jungleib tuned the specification, selected the development team, and founded Seer Systems.
