Role Summary

This profile is for the engineer(s) responsible for developing, implementing, and maintaining a
HiveMQ deployment in production — covering broker configuration and clustering, security
setup, protocol/data integrations, and ongoing operations.

Key Responsibilities
- Design and configure the HiveMQ broker/cluster topology (sizing, high availability, failover) for the target environment (on-prem, cloud, or hybrid).
- Implement authentication and authorization (TLS/mTLS, client certificates, JWT/OAuth, LDAP) using the HiveMQ Enterprise Security Extension or equivalent.
- Build and maintain topic structures, Data Hub policies/transformations, and any custom extensions needed for the use case.
- Stand up and operate integrations (Kafka/Confluent, cloud pub/sub, databases, MES/ERP/SCADA where relevant).
- Deploy, monitor, and troubleshoot the platform in production (logging, metrics, alerting, capacity planning).
- Own day-2 operations: upgrades, backups, incident response, and performance tuning.

Core Technical Skills

MQTT & Messaging Fundamentals




- Solid working knowledge of MQTT 3.1.1 and MQTT 5: QoS levels, session handling, retained messages, shared subscriptions, last will, and topic design best practices.
- Understanding of publish/subscribe architecture and event-driven design patterns.

HiveMQ Platform Depth
- Broker and cluster architecture, replication, and failover behavior.
- Enterprise Security Extension (ESE): realms, authentication/authorization managers, X.509/JWT/LDAP preprocessors, RBAC.
- Data Hub: data validation, policies, and transformations for governing message streams.
- Bridge and Kafka extensions for connecting HiveMQ to downstream systems.
- Edge protocol adapters if the deployment involves OT/industrial data sources (OPC UA, Modbus, Sparkplug B).
- HiveMQ Control Center for monitoring, client management, and diagnostics.
- Comfort reading/writing or extending a HiveMQ extension when a custom integration or business rule is re
