We are seeking a visionary Senior Backend Engineer with deep expertise in IoT ecosystems and M2M connectivity to lead the development of our next‑generation smart platform from scratch. In this role, you will architect the nervous system of our product, bridging the gap between physical hardware—such as telematics units and smart meters—and scalable cloud logic.

• Architect from Scratch: Design and implement a greenfield, microservice‑based backend architecture optimized for high-throughput IoT data ingestion.
• Hardware & SIM Integration: Directly integrate diverse hardware (Telematics, Smart Meters) and manage the M2M SIM lifecycle (provisioning, activation, and data limit orchestration) via telco APIs.
• Protocol Implementation: Develop handlers for IoT protocols including MQTT, CoAP, HTTP/2, WebSockets, and LwM2M.
• Connectivity Management: Implement logic to monitor signal strength (RSSI), manage APN con...
