Barr Group vs Voler Systems: overview
Barr Group
Barr Group was founded in 2012 and is headquartered in Gaithersburg, Maryland, with a team in the 51 to 200 employee range. Led by CTO Michael Barr, a former editor-in-chief of Embedded Systems Design magazine and author of multiple embedded software books, the firm's identity centers on training, firmware process and architecture work, and legal technical expert-witness services rather than volume staffing. For an engineering leader deciding who to bring onto a team, working alongside people whose technical writing they've likely already read is a different kind of hiring signal than a generic vendor profile.
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.

Barr Group vs Voler Systems: pros and cons
| Barr Group | |
|---|---|
| + | Michael Barr's public technical writing and books give a prospective client a way to evaluate the team's judgment before ever making contact |
| + | Training as a core business line means the firm's engineers are practiced at explaining their reasoning, not just doing the work silently |
| + | 13 years of operating history built specifically around expert technical judgment rather than headcount growth |
| + | 51 to 200 employees give real bench depth for a firm this specialized |
| - | Volume firmware development capacity is not the firm's stated focus, so a large parallel build program may need a second team |
| - | No published consulting rate or minimum engagement figure |
| - | Expert-witness work is a distinct practice from product engineering; confirm which team a specific inquiry reaches |
| 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 |
