Voler Systems vs Droid Technologies: 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.
Droid Technologies
Droid Technologies was founded in 2016 and has grown from 4 to more than 80 employees across offices in Kyiv, Kharkiv, and Vinnytsia. That growth trajectory, roughly 20x headcount in 9 years, signals a team that has been able to hire and retain specialized talent fast, specifically for embedded GUI and HMI work in LVGL, TouchGFX, Qt, and Embedded Wizard. For a hiring buyer whose product needs a strong on-device interface, this is a team where that specialty is the primary hiring focus, not a secondary skill scattered across generalist engineers.
