I am seeking an experienced PCB design and embedded systems engineer to help design a secure, industrial wireless pump shutdown system intended for remote oilfield, irrigation, and water applications.
This is a prototype / product-development project, not a hobby or consumer IoT device.
Project Overview
The system consists of:
A Master radio that monitors digital inputs (e.g., high fluid)
One or more Slave radios that actuate a relay to shut down pumps or engines
License-free 900 MHz wireless communication (long range 3-5 Miles with Proper Antennas)
2 Power Options 1) AC Power Module and 2) DC Power Module with Solar Charger & Battery Connections
Cellular alerting for monitoring and supervision
Key Technical Requirements
902–928 MHz ISM band (FCC Part 15)
Secure pairing and encrypted RF messaging
Point-to-multipoint communication (Master → multiple Slaves)
Industrial relay outputs
Heartbeat supervision and fail-safe behavior
Two power variants:
12/24 VDC with integrated solar charging (AGM battery)
120 VAC using isolated AC/DC module
LTE-M or LTE Cat-1 cellular module for SMS alerts
Ideal Background
PCB design for industrial or embedded products
RF module integration (900 MHz ISM preferred)
Power electronics (DC/DC, solar charging, battery systems)
Industrial I/O (relays, surge protection, grounding)
Experience with KiCad, Altium, or Eagle
Oil & gas, water, or remote telemetry experience is a strong plus
Deliverables
Schematics
PCB layout (Gerbers + native files)
BOM with part numbers
Bring-up and test notes
Power and RF design documentation
