RMB Consulting vs Zone7 Engineering: overview
RMB Consulting
RMB Consulting has operated in embedded systems design and consulting since 1995, run by founder and chief engineer Nigel Jones, who brings more than 30 years of professional embedded systems engineering experience and a long-running record of public technical writing on firmware design. For a client hiring a small team, working directly with a single named, 30-year-tenured engineer, rather than being assigned whichever staff member is available, is close to the smallest and most direct version of an engineering-hire relationship this list offers.
Zone7 Engineering
Zone7 Engineering is a Portland, Oregon electronics engineering practice founded and run by David Ashman, a senior electronics engineer with extensive experience designing digital and analog circuitry around various microprocessors and DSPs alongside embedded C/C++ firmware development. For a client evaluating the smallest possible version of an engineering-hire relationship, this is a firm where the person quoting the project, designing the architecture, and writing the firmware are the same single named individual.
