MQTT Architect - IoT

Job Description :

We are looking for an experienced MQTT Architect with 12 - 18 years of experience in designing and implementing scalable, secure, and high-performance IoT integration solutions.

The ideal candidate will have strong expertise in MQTT broker and cluster architecture, MQTT v3/v5, IoT integration, networking, cloud platforms, event streaming, security, and edge protocols.

The candidate will be responsible for translating high-level architecture concepts into practical implementation designs and driving the development of robust MQTT-based solutions for OT/IoT and Industry 4.0 environments.

Key Responsibilities :

• Design and architect scalable, highly available, and secure MQTT-based solutions for IoT and enterprise integration.

• Provide strong technical expertise in MQTT broker and cluster architecture, including publisher, subscriber, applications, IoT devices, and data integration components.

• Design and implement solutions using MQTT versions 3.x and 5.

• Work hands-on with MQTT broker products such as HiveMQ and EMQX.

• Define MQTT architecture, communication patterns, topic structures, QoS strategies, authentication, authorization, and security mechanisms.

• Design MQTT solutions for real-time IoT data ingestion, device communication, and event-driven integration.

• Enable integration between MQTT platforms and IoT/OT systems, enterprise applications, and cloud services.

• Design and implement integrations with event-streaming platforms such as Kafka and Azure Event Hub.

• Work with cloud platforms such as AWS, Azure, and other cloud environments to build scalable IoT solutions.

• Ensure high availability, fault tolerance, scalability, and performance of MQTT broker clusters and associated integrations.

• Develop integration strategies across devices, edge systems, MQTT brokers, applications, and data platforms.

• Collaborate with networking and security teams to define secure communication and network architecture.

• Address security and encryption requirements across MQTT and IoT environments.

• Analyze and troubleshoot connectivity, networking, protocol, performance, and integration issues.

• Provide technical leadership in translating high-level architecture designs into detailed implementation solutions.

• Work with engineering teams to establish architecture standards, development practices, and implementation guidelines.

• Support the integration of OT and IoT systems with enterprise and cloud platforms.

• Evaluate and recommend appropriate technologies, protocols, and architectural approaches for IoT use cases.

• Contribute to Industry 4.0 initiatives and connected-device transformation programs.

Required Technical Skills :

• Strong knowledge of MQTT (Message Queuing Telemetry Transport).

• In-depth knowledge of MQTT v3 and MQTT v5.

• Hands-on experience with MQTT brokers such as HiveMQ and EMQX.

• Strong understanding of MQTT broker and cluster concepts.

• Experience implementing MQTT for IoT-based integration.

• Strong understanding of integration architecture and enterprise integration concepts.

• Strong knowledge of networking concepts, protocols, and connectivity.

• Familiarity with event-streaming technologies such as Apache Kafka and Azure Event Hubs.

• Understanding of cloud concepts and cloud-based architectures, preferably AWS/Azure.

• Proficiency in scripting or programming languages such as Python and JavaScript.

• Strong understanding of security, authentication, authorization, and encryption.

• Knowledge of OT and IoT systems and their integration requirements.

• Understanding of Industry 4.0 standards and architectures.

• Knowledge of low-level communication protocols and edge/network protocols.

Preferred Skills :

• Experience designing enterprise-grade IoT and MQTT platforms.

• Experience with MQTT cluster scalability and high-availability architectures.

• Knowledge of MQTT security mechanisms, including TLS/SSL, authentication, authorization, and certificate-based security.

• Experience integrating MQTT with Kafka, Azure Event Hub, cloud platforms, and downstream applications.

• Understanding of edge computing and edge-to-cloud architectures.

• Experience working with industrial/OT environments and connected devices.

• Knowledge of industrial communication protocols and edge technologies.

• Experience with performance tuning and capacity planning for distributed IoT platforms.

• Strong understanding of API and event-driven integration patterns.

What You Will Do :

• Architect scalable and secure MQTT solutions for enterprise IoT environments.

• Enable real-time IoT integration and reliable data flow between devices, edge systems, applications, and cloud platforms.

• Ensure high availability, scalability, security, and performance of MQTT-based platforms.

• Drive innovation across IoT and Industry 4.0 initiatives.

• Collaborate with cloud, networking, security, application, and engineering teams to deliver end-to-end solutions.

• Bridge the gap between high-level architecture and ground-level implementation details.

Ideal Candidate Profile :

• The ideal candidate is a senior technology professional with strong MQTT, IoT, integration, networking, and cloud architecture expertise.

• They should be comfortable working at both the architecture and implementation levels, with hands-on experience in MQTT brokers such as HiveMQ or EMQX.

• Strong knowledge of MQTT v3/v5, IoT/OT integration, Kafka/Azure Event Hub, cloud platforms, security, networking, scripting, and edge protocols is essential.

• The candidate should also be capable of providing technical leadership and designing reliable solutions aligned with Industry 4.0 requirements.
