Embedded System Designer - Analogue measurement module

******PLEASE DO NOT BID IF YOU DO NOT UNDERSTAND THE REQUIREMENTS.******

We are looking for an embedded system engineer to work with us on developing analog-to-digital measurement modules.
The job requires developing 8 channel input board for measuring 50/60Hz current and voltages with a microcontroller having CAN bus.

+++ Measurement channels:
4 x current input 1 A
4x voltage input – 100 VAC
Current inputs are designed for nominal current In=1 A (AC) and voltage for the nominal voltage of 100 VAC.

+++ Overloads
Current inputs - possible overload up to 100 A for 1 second.
Voltage inputs overload up to 500VAC for 1 second.

++++ Accuracy Class
Inputs measurment class 0.5.

+++ Sampling rate and resolution
ADC sampling to be at LEAST 6kHz with a resolution better than 18-bit resolution.

+++ Digital filtering
Filtering of the digital signal with a digital low pass filter for frequencies of up to 500Hz.

+++ Communication
Board has to have a CAN FD bus (5Mbit).

***************** Design work includes : *********************************
- block diagram and working principle
-current is measured by a small PCB-mounted current-sensing transformer
- selection of principal components (ADC's, filters, shunts, CTs, OpAmps, filters, MCU, CAN transceivers, etc.)
- schematic and PCB layout in KiCAD with micro USB port for programming and also debugging
- BOM with all details and components
