Role Description

• Develop, customize, and maintain firmware for the Senseceiver 4-20mA, Modbus hardware
• Interface with 4–20mA/ Modbus industrial sensors, ADCs, and embedded peripherals
• Handle cloud connectivity: integrate with AWS IoT and Cumulocity IoT using MQTT over LTE/CAT-M
• Configure and manage sensor thresholds, local actions, and digital output triggers
• Implement firmware OTA updates, USB configuration tools, and MQTT messaging formats
• Manage edge logic to trigger alerts based on sensor readings and send structured cloud payloads

Develop firmware and embedded Linux applications for Gateworks SBCs (NXP i.MX8-based)

Integrate with robotic control systems and sensors over industrial interfaces (CAN, UART, GPIO, Ethernet)

Design real-time communication modules between sensors, actuators, and the robot’s control systems

Build robust API or data communication layers to sync with higher-level robot applications

Ensure reliable, secure boot and OTA mechanisms on embedded Linux systems

Assist with rugged field testing, deployment, and system hardening for railway environments

Requirements:

• Bachelor's degree in Electronics, Computer Engineering, Mechatronics, or related field
