We are looking for an LoMT Engineer to join our team in India! Key responsibilities are: Design, develop, and maintain C++ and C# components for secure device-to-cloud and device-to-gateway communication. Implement MQTT 5based messaging between devices and gateways, including topic management, QoS handling, and retained messages. Integrate Event Grid publishing and subscription mechanisms for cloud event propagation and telemetry ingestion. Develop modules for device provisioning, certificate lifecycle management, and secure onboarding in alignment with PKI policies (e.g., DigiCert Trust Lifecycle Manager).

Collaborate closely with cloud, edge, and cybersecurity teams to ensure robust, compliant, and scalable device connectivity. Support debugging and diagnostics for deployed agents, including MQTT communication traces, Event Grid delivery, and certificate renewals.

58 years of professional experience in software engineering with strong expertise in modern C++ (C++17 / C++20) and solid proficiency in C#. Proven experience with MQTT 5 and event-driven communication systems. Solid understanding of network protocols (TCP/IP, HTTPS, gRPC) and asynchronous I/O.
