Linux Software Developer - Kernel

Nielsen

Koper, Slovenia

About the role

We are the hardware engineering group that designs and implements embedded systems (meters) for collecting TV tuning and TV viewing data. Our team’s responsibilities include electrical schematic design, circuit board layout, and enclosure mechanical design. We use contract manufacturers to build prototypes and production meters. Typical meter designs consist of a single main board with a dozen or more integrated circuits (BGA, QFP, TDFN, SOT, etc.) and related passive components. Our designs range in size from rack mount equipment to devices as small as a wrist watch. We design and create automated manufacturing test systems that incorporate various instruments such as optical detectors, power supplies, DVMs, RF generators, and frequency converters. These test systems are used to validate newly manufactured equipment.
