ECG blood pressure monitor testing kit

We develop a ECG and blood pressure monitor combo + mobile app. For this purpose, we require to work with an experienced firmware developer for the long term (several testing iterations, testing of algorithm viability, enhancing product). The minimal experience requirements are:
1. Have knowledge about STM32 microcontroller
2. Skill in Keil/STM32Cube
3. Have knowledge about Bluetooth communication because our device need to communicate with app
Our device will be used for medical testing purpose.
The core components:
1. STM32F405
2. ADS1293 ECG IC
3. CC2541 Bluetooth chip
4. Analog circuitry for BP rate test
Note: As a developer you have to capable to write code for STM32F405 and the ECG IC. You will write the code and send to us, we will test the device at our end, remote desktop setup also can be available.
