If you like what we do, see our offer — maybe it is you we will have the pleasure to meet! :)

You will work on a complete node-to-cloud architecture, designing cloud-native services and scalable communication patterns that connect embedded devices, cloud platforms, and management applications. A key part of the project involves building secure device identity and provisioning mechanisms based on X.509 certificates, TLS/mTLS, and modern authentication frameworks. Working closely with embedded engineers, you will help develop a new Network Management System (NMS) responsible for device registration, heartbeat monitoring, telemetry ingestion, configuration deployment, device state management, and command execution. The platform leverages MQTT, REST APIs, and event-driven architectures to support reliable device communication, configuration versioning, rollback mechanisms, and secure OTA update workflows.

This is a unique opportunity to work at the intersection of Cloud Engineering, IoT, Security, Networking, and Distributed Systems, while helping shape a scalable platform from the ground up.
