Service integrations - Connecting platform capabilities to shared services including identity and access management, weather data, utility tariff data, notification delivery, and audit logging
Real-time telemetry pipeline - Processing industrial telemetry from MQTT/Sparkplug B message streams via Azure Event Hub, including message decoding, metric normalization, knowledge-graph-based enrichment, and downstream publishing
Command and control path - Implementing the outbound command path to industrial equipment with acknowledgement verification
Data persistence and query - Working with time-series databases, graph databases, and object storage to support operational and analytical workloads
Infrastructure and deployment - Containerized services running on Azure Kubernetes Service (AKS), with CI/CD pipelines and infrastructure-as-code

Requirements

Familiarity with event-driven architectures and message brokers (Kafka, Event Hub, MQTT)
Experience with containerization (Docker, Kubernetes, Helm)
Working knowledge of CI/CD pipelines (GitHub Actions or Azure DevOps Pipelines)
Comfort with infrastructure-as-code (Terraform, Bicep, or Pulumi)

Preferred skills:

Experience with industrial protocols (Sparkplug B, OPC-UA, Modbus, BACnet, SNMP)
Background in energy management, SCADA, or building management systems
Familiarity with graph databases or RDF triple stores
Experience with time-series data at scale (Azure Data Explorer / Kusto, InfluxDB, TimescaleDB)
