Project Description:
NEONPULSE is a modular IoT ecosystem that establishes connectivity between any metering technology (electricity meters, gas meters, water meters, heat meters, multimeters, IoT sensors, etc.) and any target applications (energy portal, Optimum, Thingsboard, etc.). It organizes data flows and ensures data integrity. NEONPULSE enables all client units to implement IoT use cases in critical and non-critical infrastructure, buildings, or areas.

Tasks:

• Implementation of IEC 60870-5-104 communication according to customer requirements for the NEONPULSE remote control device
• Establishing IPSec VPN encryption between the remote control device and the SmartM2M router
• Implementing secure boot based on TPM for i.MX8 architecture
• Integration of trusted chain boot process
• Signing firmware via GitLab pipeline
• Signature validation via TPM platform
• Static code analysis using SonarQube

Skills:
Must Have:

• Programming languages: C/C++, Go, Python
• Strong knowledge of IEC 60870-5-104 (telecontrol TCP/IP-based)
• IPSec (IKE, ESP, AH)
• Operating system: Linux
• Embedded systems: Linux (x86/ARM), Yocto, Buildroot

Nice to Have:

• Security: i.MX8 HAB (SecureBoot)
• Bus systems: Modbus RTU/TCP
• Microcontrollers: ARM cores (NXP, STM32)
• CI/CD: GitLab
