Role Summary :

RedRaven is Flowserve’s complete end-to-end solution for the industrial space to monitor and optimize flow control equipment performance and proactively identify and address issues before they cause downtime and disruptions. 

We are looking for a Senior IoT Engineer with deep expertise in PTC ThingWorx and the surrounding IoT ecosystem (Azure, MQTT, databases, and data historians). The candidate will architect, develop, and optimize ThingWorx-based IoT solutions for device connectivity, real-time analytics, visualization, and system integration. 
 

This role also requires hands-on experience in developing custom ThingWorx Java Extensions and strong problem-solving skills in distributed, data-heavy environments. 

Responsibilities :

ThingWorx Platform Development 

• Design and develop complex ThingWorx services, DataShapes, ThingTemplates, and Mashups for large-scale industrial IoT solutions. 

• Implement scalable logic for data ingestion, transformation, visualization, and event-based analytics. 

• Optimize ThingWorx services for performance, memory usage, and large InfoTable handling. 

• Configure and manage Value Streams, Data Tables, and persistence providers (PostgreSQL, InfluxDB, etc.). 

• Build dynamic UI dashboards and KPI visualizations aligned with asset hierarchies and customer-specific contexts. 

Custom Extension Development (Java SDK) 

• Develop ThingWorx Java Extensions using the ThingWorx SDK for custom functionalities beyond platform capabilities. 

• Implement reusable Java-based services, event handlers, or connectivity modules. 

• Manage extension lifecycle: design, build, sign, package, and deploy via the ThingWorx Composer. 

• Integrate with external systems (e.g., MQTT, Kafka, RabbitMQ, PI Web API, REST, SOAP) through secure and performant extension code. 

• Follow best practices for logging, exception handling, threading, and resource management in extensions. 

Integration & Data Handling 

• Work with Azure IoT Hub/Event Hub, RabbitMQ, or MQTT brokers for large-scale device communication. 

• Design and implement data pipelines between ThingWorx, external databases (Postgres, InfluxDB), and cloud storage systems. 

• Integrate time-series historians (e.g., OSI PI Web API, AVEVA Historian, etc.) for historical and batch analytics. 

• Implement efficient batch APIs, JSON parsing, and bulk processing mechanisms 

Architecture & System Design 

• Define and document ThingWorx architecture, entity design standards, and naming conventions. 

• Evaluate and improve scalability, security, and maintainability of IoT deployments. 

• Collaborate with IT teams for infrastructure activities. 

• Support CI/CD integration, version control (Git), and automated deployments for ThingWorx artifacts. 

Requirements :

• Bachelor's or Master's degree in Computer Science, Electronics, or related engineering field. 

Preferred Experience / Skills :

• Strong problem-solving and debugging mindset for complex multi-system IoT issues. 

• Excellent documentation, design, and communication skills. 

• Ownership-driven attitude with a focus on scalable and sustainable design. 

• Experience vibration monitoring systems. 

• Exposure to Edge device integration (LoRaWAN, Modbus, OPC-UA, etc.). 

• Knowledge of Docker-based ThingWorx deployments or Kubernetes.
