After working at Lawrence Livermore National Laboratory, IBM Research Division in San Jose, and Hewlett-Packard Laboratories in Palo Alto, Brobst founded multiple start-up companies focused on data management products and services. He founded Strategic Technologies & Systems in 1983 while he was a graduate student at MIT. STS was acquired by NCR Corporation in 1999. From 1993 through 2000 he was co-founder and chief technology officer at Tanning Technology Corporation, a services firm focusing primarily on the implementation of Oracle databases for transaction processing. Tanning executed an initial public offering in 1999 and was later acquired by Platinum Technologies. He co-founded NexTek Software in 1994, a firm that created a software product for workload management for relational database management systems, as a spinoff from Tanning Technology Corporation. IBM acquired technology from NexTek in 1998 which provided the software foundation for early versions of the DB2 Query Patroller. Brobst was involved in the creation of eHealthDirect, a software start-up for automated claims adjudication using rule-based systems for the health care industry, between 1999 and 2002. eHealthDirect was acquired by HealthEdge in 2003.
Simultaneous with the acquisition of Strategic Technologies & Systems in 1999, NCR Corporation created a separate division for the Teradata relational database management system. Brobst was appointed as Chief Technology Officer for the newly formed Teradata Division and continues to serve in this capacity today. Teradata was spun off as a separate company and went public on the New York Stock Exchange on October 1, 2007.
Brobst lectured at Boston University in the computer science department between 1984 and 1992 while working toward his PhD at MIT. He taught undergraduate courses in operating system design, data structures and algorithms. He taught graduate courses in advanced database design as well as parallel computer architecture. Brobst has taught at the Data Warehouse Institute since 1996. In 2001 Brobst worked with a team of academics in Pakistan to develop a course curriculum for database design and analytics. He participates in the Girls Who Code initiative, teaching computer science concepts to high school girls.
