Zone7 Engineering vs EES: overview
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.
EES
Embedded Engineering Solutions (EES) was launched in 2012 and is based in Tempe, Arizona, with reported headcount varying across sources from roughly 3 to 50 employees, most consistently described as a small, senior-led firm. The company specializes in contract firmware, embedded systems, and hardware design engineering for the industrial sector, and its own positioning leans on being senior-led rather than layered with junior staff. For a hiring buyer specifically avoiding a large delivery organization, that's the stated value proposition, not an incidental trait.
