Voler Systems vs Zone7 Engineering: overview
Voler Systems
Voler Systems has operated from Sunnyvale, California since 1979, a 46-year run that means most of its roughly 22 engineers have deep, overlapping tenure rather than a constantly rotating bench. The firm combines analog circuit design, FPGA programming, and embedded firmware, with a specific focus on ultra-low-power wearable and biomedical sensor products. For a client evaluating team stability, a firm that has retained its identity and core expertise for over four decades signals something different than a firm assembled quickly to staff up for a hiring surge.
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.

Voler Systems vs Zone7 Engineering: pros and cons
| Voler Systems | |
|---|---|
| + | 46 years of continuous operation suggests a team with deep institutional knowledge, not high turnover |
| + | Combines analog, FPGA, and firmware disciplines in one small team, reducing the number of specialists a client has to coordinate |
| + | Ultra-low-power design expertise built up over decades of the same core focus area |
| + | 22-person size means direct access to senior engineers, not junior staff routed through a larger organization |
| - | 22 engineers means a client needing several concurrent teams should confirm capacity before committing |
| - | Public case study volume is thinner than its tenure would suggest, worth a direct reference conversation |
| - | No published pricing or minimum engagement figure |
| Zone7 Engineering | |
|---|---|
| + | Founder-led model means the person quoting a project is the same person who designs and builds it, with no account-management layer |
| + | Covers project planning through PCB design, firmware, prototyping, and production readiness in one continuous process |
| + | Analog and digital circuit design experience alongside firmware covers mixed-signal product requirements |
| + | 15 years of practice predates many boutique competitors on this list |
| - | Solo or near-solo team size severely limits capacity for a project requiring multiple concurrent workstreams |
| - | Public case study detail and named client references are very limited |
| - | No published pricing or minimum engagement figure |
