"We have developed a custom PCB with a Bluetooth 4.1 module, WiFi, flash memory, and custom power supply and are looking for an experienced embedded systems developer to program the firmware and API. We need the custom board to interface with our backend server which will present commands via the WiFi module to manage the Bluetooth module (ex. change UUID, tx rate, power, etc)
Details on the specific Bluetooth and WiFi modules will be sent upon application and review of credentials.
The board will also need to communicate with an iOS application that is not built yet and might become part of the project if relevant experience is displayed.
Please apply with relevant background experience highlighted in the application"
