What you will do :
- Design, develop, and maintain MQTT APIs and services for real-time telemetry data exchange.
- Build high-throughput data ingestion pipelines integrating MQTT brokers with Azure Data Lake Storage and Microsoft Fabric.
- Integrate telemetry platforms such as Ignition with cloud-based data platforms.
- Optimize APIs and messaging infrastructure for scalability, reliability, and low latency.
- Develop REST APIs and microservices to expose telemetry data to downstream applications.
- Implement authentication, authorization, and secure communication for MQTT services.
- Monitor, troubleshoot, and resolve production issues related to messaging and data pipelines.
- Collaborate with OT, IoT, cloud, and analytics teams to deliver end-to-end solutions.
What you will bring :
- 3 to 6 years of experience in MQTT, API development, or IoT application development.
- Strong hands-on experience with Azure Data Lake Storage, Microsoft Fabric, and telemetry systems such as Ignition.
