Embedded OS Engineer Intermediate/Senior (with Linux)

For more than 30 years, our client has partnered with leading quick service and fast-casual restaurants in employing best-of-breed restaurant technologies to grow their businesses. Through one powerful platform, it delivers an end-to-end suite of purpose-built solutions for quick service and fast-casual brands, franchisees and restaurant managers to effectively manage, control and standardize their processes, while capturing the data insights needed to drive continuous improvement and greater profitability.

The project we need your help with concerns the digital menu boards installed in over 25,000 locations worldwide. Digital Menu Boards as a product consists of 2 main devices in different configurations: one is the display screen (usually from 3 to 8 in one location) responsible for displaying the dynamic menu of a restaurant (for instance, the breakfast menu with animated coffee cup and donuts), and the other is a media player where cron jobs are running to retrieve content and configurations from web portal, process these files, and deliver them to the display screen.

Firmware is based on Yocto project and build to meet requirements of Chromium-based environment of the restaurant menu visual presentation.
