Zone7 Engineering vs Ripcord Designs: 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.

Ripcord Designs

Ripcord Designs is a UK-based electronic and embedded software design consultancy operating from the London and Cambridge area, founded around 2015 by Adam, previously Engineering Director at Broadcast Sports. That career move, from managing engineering at a larger company to building a smaller hands-on practice, is a specific signal about the kind of team a hiring buyer would be working with: senior technical judgment applied directly, not delegated down through management layers. The firm spans MedTech, IVD and lab devices, robotics and industrial, and consumer electronics work.
